Turnabout Memories - Part 14

Broadway Malady
Note to self: typing with just one hand because of a broken elbow is time consuming. That is why this post is a bit shorter than usual.
Detective Conan volume 106 was released in October 2024, about six months after the 2024 film Detective Conan: The Million-Dollar Pentagram, but it's main story is closely related to that film's plot and functions as a kind of epilogue, so it is worth it to first watch the film before reading this volume to get the intended effect. However, the volume itself starts with a fairly normal story: The SOS Message Delivered by Torakage started in the previous volume and has Conan and the gang notice a neighborhood playing with a piece of paper, on which someone called Saori asks for help. Meanwhile, Inspector Sato and Takagi are chasing after a kidnapper, who manages to escape, get rid of his jacket and disappear in a restaurant in the Yokohama Red Brick Warehouse. Because the kidnapper saw Sato, it's Takagi and Shinagawa traffic police officer Chihaya who enter the restaurant (posing as a couple) to find the kidnapper.
As you can guess, this story develops on two fronts: Conan and the Detective Boys found a note signed by the kidnapped Saori, meaning she should be nearby, while the plot set in the Yokohama Red Brick Warehouse is a classic "which of the three suspects" set-up. I have to admit nether side really managed to impress me: the ultimate step to determine who the kidnapper is, is something the reader can't predict (any of the three could have been the kidnapper even with the decisive clue obtained), so it doesn't really feel fair, while the plot about the search for the kidnapped girl rvolves a lot around coded messages, and those often feel just like trivia storiees, like it did here.
The Enamoto Azusa Abduction Case starts in Cafe Poirot, where Ran, Sonoko, Sera and Conan are having a drink while watching Azusa and Amuro helping the other customers, When they run out of a certained herb-infused salt, Conan says he knows a shop in the neighboring district that stocks it, so he and Azusa go out for groceries, but they soon realize they're being followed. They try to make it back to Poirot, but are abducted right in front of Amuro and the others. A bystander overheard Conan and Azusa cry out the kidnapper was someone with a cough who was just now in the cafe: three men appear the main suspects: one who seemed intent on getting the recipe for Poirot's beef stew, another customer who asked Azusa to keep something secret and a man who was having coffee at the counter. Meanwhile, Azusa wakes up to find herself and Conan chained in a dark room and to her great surprise.... she sees a decapitated head in a glass jar. Have they been kidnapped by the notorious serial killer who's been terrorizing the city lately?
This was a simple, but okay story, considering its limited space. When Azusa wakes up, she uses Conan's Detective Boys badge to contact the people at Poirot, just as the abductors enter the room. Amuro and Sera overhear the culprits mentioning they will get rid of Azusa and Conan in four hours, once it's midnight, but then the kidnappers notice the badge and destroy it. However, this does allow for the story to do some The Nine-Mile Walk-esque deductions about what's so special about midnight and how it could pertain to the three suspects. Ultimately, the story is not that grand and many may easily guess where it's going, but I liked it. I wonder if the story's plot came from sonething Aoyama himself experienced....
The Curse of The Demon Puppeteer is a long story and the sequel to volume 102's Kyoto Sweets and Poison. The stage play based on Mouri Kogorou and Hattori Heiji has finally been performed, despite the death of the director in the previous story. Kogorou, Ran and Conan, as well as Hattori and Kazuha are of course present in the audience as the show is done in Osaka. After the succesful show however, one of the actresses falls of a building, followed by her phone falling next to her, with a message signed by "the Demon Puppeteer", the nickname of the deceased director because of he controlled his actors. It seems a lot of jealousy is going around backstage among the actors, and soon more deaths follow, all signed by the the Demon Puppeteer...
Oh, and there's of course still that subplot where Hattori is looking for the perfect place to confess his love to Kazuha...
I'm torn on this story! It's not one to be really memorable on its merits of plotting and tricks per se: as a mystery, the elements Aoyama used are likely to feel familiar one way or another and I don't like the clewing that much. On the other hand, I defintely liked how this tale built further on Kyoto Sweets and Poison and introduced an interesting cast (literally) for this series of murders. The story also has some implications for the ongoing story and introduces a new character in a way that is probably not as surprising as intended. So a story I can appreciate for its story/characters, but I had hoped for something grander trick-wise, as lately, a lot of the stories seem to rely too much on trivia or otherwise using the latest fad.
I can't say Detective Conan volume 106 really managed to overturn the trend of somewhat mediocre stories mystery-wise the last two years or so, but I think I liked it better than the previous one on the whole. The next volume has no official release window announced by the way, so I guess it'll release around April when the 2025 film hits the theaters... Really looking forward to that film by the way, so I'll try to review it as soon as I can!

The Vanishing Victim Mystery
I discussed a Komori novel early this year, so why not have one in December too, especially one that has a tie to Christmas? Like Nnwenre no Serdab ("The Sealed Chamber of Nnwenre", 1996), Jesus Christ no Misshitsu has an Egyptian theme as the book mostly revolves around a two-part account of an Egyptian who was in Jerusalem before Jesus arrived there, and who investigated the resurrection of Jesus several months later: this account is book-ended by the tale of the person who stumbled upon the papyrus rolls. As a mystery, the resurrection of Jesus is of course easily reimagined as a locked room mystery: if the tomb where Jesus' body was being kept in was sealed and guarded, how did he escape? Some years ago, I reviewed Kujira Touichirou's Yamataikoku wa Doko Desuka? ("Where is Yamatai-koku?" 1998), which contained the short story Kiseki wa Dono You ni Nasareta no ka? ("How Was The Miracle Accomplished?") where the characters refer to the bible and reinterpret the sources to give a rational explanation to the Biblical resurrection of Jesus. That series is set in contemporary times, with (amateur) scholars using quotes from real-life sources to offer new insights/theories regarding history. In that respect, Komori's book is quite different, as it is portrayed as the story of someone who was there at the time.
The first third/half of the book is set before Jesus arrives in Jerusalem, but the Egyptian interpreter has already heard many rumors about him, so he sets out to interview people from various circles in society to see what they think of Jesus. We get to see a lot of very short portraits of Jesus, with some people thinking very highly of him, while others see Jesus as nothing but a nuisance. Komori quotes a lot from the various bible books, refering to certain episodes that help shape all the different images people have of Jesus. Personally, I found this part a bit boring, as while this may work for say two or three times, I felt Komori was just overdoing it by the time we're reading like the fifteenth different opinion on Jesus. What's more, all of this doesn't have a direct connection to the later mystery: it's just presenting the different views people have of Jesus, and I guess this part is important for people who aren't that familiar with the bible, but even then, I couldn't help but feel like this was just padding (and the book itself is actually already quite short).
In the second half, the Egyptian interpreter returns to Jerusalem only to learn about Jesus' supposed resurrection and about how he disappeared from the tomb. The mystery here is two-fold: there are witnesses who say they saw Jesus after his death, so it appears he did ressurect, but how? And how did he escape the place where his body was being kept after being crucified? While the set-up is interesting (and one many, many people on this world will be familiar with), I have to say there are few times I was so disappointed. For even though Komori referenced the bible extensively in the first part of the boook, the setting for this mystery as painted by Komori is quite dissimilar to what you'd usually associate with the episode of the empty tomb. In this book, Jesus' body wasn't even actually kept in a tomb, but a cave that was sometimes used as a toilet (and now used as a temporary morgue) and there wasn't even a boulder in front of the cave to seal it, but just a door that could be locked! At this point, it felt like there were so many elements that strayed from what I would assume to be the mystery of the empty tomb from the bible, I have to admit I lost my investment in the story. The way the interpreter arrives at his solution to how Jesus could have resurrected, and also how Jesus' body could've disappeared from the tomb even though it was kept locked and there was only one key in possession of someone who would not have any reason to help Jesus and his disciples, actually has clever parts to it, and you can see Komori really did do proper research regarding the bible, the (theological) culture and time period, but so much of it is not part of the commonly known story of the empty tomb, and at that point, it might as well have been not about Jesus Christ. And again, the book is very short, so I feel like a short story, set in this period but not based on the bible, could have worked even better.
So I can't say I really enjoyed Jesus Christ no Misshitsu very much. Mystery-wise, it didn't really make use of the fact it was based on a well-known episode from the bible, introducing all kinds of original elements in order to make the mystery work. While Komori obviously did do his homework before writing this book, it seems like creating a properly clewed locked room mystery based on the New Testament was a bit too tricky, forcing him to add in more elements to flesh the setting out, but by doing so, it feels he strays too far from the basic setting.

Steal Me a Story
The faces on the covers for Mitsuda's books published by Kodansha are always really creepy...
I have read a lot of Mitsuda Shinzou's work in the last few years and have become a great fan of his work, but with a caveat: save for a short story I never reviewed here, all I have read by him is his Toujou Genya series, where he mixes folklore and horror with insanely brilliantly plotted mysteries. I can't overstate how crazy the quality level remains throughout the series, and the books always end up in my favorite reads of the year. Ikan is the first novel I have read by Mitsuda that isn't part of that series and it is also Mitsuda's debut novel: it was originally published with the title Horror Sakka no Sumu Ie (The House Where a Horror Writer Lives), which is now the subtitle of the book, and it is the first entry in a three-part series. Being up-to-date with the Genya series currently, I decided to fan out, and I figured, why not with his debut work?
Ikan is a tale of horror told in a rather complex manner: besides the narrative of Mitsuda finding the titular house and slowly encountering more and more odd situations and people, there is also a narrative-within-a-narrative structure, as we also get to read all the installments of Mitsuda's serialized story as it is published each time: his story is based on his experiences in the house, and tells the story of a core family moving into a British-style house as seen from the POV of the younger son. The younger son soon finds hidden compartments in the house, and even a strangely built doll house that seems to be a copy of the very house they are living in. And oddly enough, Mitsuda too comes across the very things he writes about in his serialized story...
The mystery of how all of this is connected and how both the narrative-within-a-narrative, and the "outside" world narrative will end is suspenseful, but also told in a manner that can at times make it difficult to keep track of everything. Many "puzzle pieces" are constantly being introduced, but often, they don't even feel like from the same set, and so you feel like there's too much chaos in the plot. While things do come together in the end, it is definitely not the "densily clewed mystery with lots of synergy" we've learned to expect from the Genya series. The Genya series features a lot of the
horrendous and mysterious events that are eventually given a rational meaning via either the core mystery plot, or folklore analyses, but in this book, a lot of
the core horror elements remain unexplained, and in that sense, I do feel the book is less satisfying. Especially the events in the narrative-within-a-narrative feature a lot of events that are not explained in detail, and while they may not be directly connected to the core mystery, it leaves you with so many questions that seemingly are only answered by "yes, the supernatural exists": I am not against the supernatural in mystery fiction, but without clear rules, you just have no idea what to expect and not, and here, the horror elements remain shrouded in the shadows. So Ikan is definitely leaning more into the horror
than the Toujou Genya series and the conclusion is more like the twist ending (with foreshadowing) you'll expect from conventional horror mysteries, rather than a dense honkaku puzzle with a surprising, yet convincing twist.
I believe the epilogue is only available in the current version from 2008 (which I read), which tries to flesh out the background a bit more, but don't expect too much of it.
Ikan - Horror Sakka no Sumu Ie can be read as an entertaining horror novel, with a mystery writer slowly being absorbed by his own fictional creation, but I wasn't really looking for that, so in that sense, it's a bit of a disappointment: it is certainly not in any way a proto-Toujou Genya novel in any way. While there are more books in this particular series, Mitsuda Shinzou has many other series available, so I will probably try those out first to see if he has other books that can give me Genya-esque experiences.

Triple Death
The Honkaku Suiri ("Orthodox Deductive Fiction") and Shin Honkaku Suiri ("New Orthodox Deductive Fiction") anthologies were published between 1993 and 2009 by Kobunsha and were conceptualized as a place where amateur writers could send in their short stories to: publisher Tokyo Sogensha currently has the Sogen Mystery Short Story Award (formerly known as the Mysteries! Newcomer Award) as a counterpart to the Ayukawa Tetsuya Award, which focuses on novel, but that didn't exist yet back in 1993. The original series was edited by Ayukawa Tetsuya, and the Shin series by Nikaidou Reito and supervised by Ayukawa Tetsuya (until he passed away in 2002) and in the fifteen or so years the anthology existed, a lot of people were selected who'd later on become well-known mystery writers, like Mitsuda Shinzou, Ooyama Seiichirou, Ookura Takahiro, Kirisha Takumi, Kuroda Kenji, Tsukatou Hajime and more. Interestingly, I don't think most of them consider having their stories published in these anthologies as "their debut moment", even though it'd be their first "formal" publication. In a very far-away past, I read the last Shin Honkaku Suiri anthology, which was actually one of the earliest books I read in Japanese.
Shin Honkaku Suiri 3 ("New Orthodox Deductive Fiction 3") was published in 2003 and features the subtitle The Heirs to Villa Lilac, a reference to one of Ayukawa's novels. This third entry in the Shin series would also be the final volume supervised by Ayukawa, as he passed away a few months before this book was published (I assume his work had already been finished by then). While I usually review all, or at least most, stories in an anthology, I'll only discuss three of the eight stories (+ essays) included in this book this time: not because the others are bad, but because I was borrowing this book and only had time to read three of them before returning it! So I might return to this other stories in this book in the future, but that's no promise, though going by the quality of the stories I did read, I probably really should read them.
This book features the first time Onuki Kazaki was ever selected for the anthology, but interestingly enough, they got selected three times: three of the eight stories in this book are penned by them. The book also opens with one of them: Tomurai Tetsudou ("The Mourning Railway"), a title reminiscent of Oosaka Keikichi's Tomurai Kikansha ("The Mourning Locomotive"). The story opens with Kasuga Karin sitting all alone on a bench at the station of Inone, a small village. Earlier that day, she attended the funeral of an uncle and was now on her way back home, when she fell asleep in the train. When she woke up, she thought she was at the station Noboribou, where she needed to transfer, so she jumped out. Unfortunately, she got out one station too early. Because it was the late afternoon, she figured more trains would follow... only they didn't, and the busses to Noboribou had also stopped. By the time she figured that out, it was already night and rain had started to fall, making it dangerous for her to walk the way to Noboribou and because the village of Inone is so small and surrounded by the forest, no cars pass by to pick her up. A young man approaches her suddenly and quickly guesses why she's sitting with such a hopeless expression on her face at the station. He offers to pay for her stay at the inn where he'll also be staying. She's a bit suspicious of him, but ultimately accepts his offer. She learns he's interested in a terrorist who's been bombing train lines lately that are financially unviable. Rumors have it they might strike on the train line connecting Inone and Noboribou. That evening, Karin notices the young man went out in the night, and returned... with a bomb. What is he exactly and what is his true motive for helping Karin?
Like I mentioned, the title invokes the famous Oosaka story, and in a way, it has a similar set-up in the way there's no clear mystery in this story. The young man acts suspiciously, but Karin can't figure out whether he's the bomber or not, but the story doesn't focus on Karin trying to investigate that: the story continues the next day, when everyone has to take public transport to Noboribou, and it's then the story reveals its true nature. It's a very clever plot, that might remind people of Father Brown stories, A Aiichirou stories or The Nine Mile Walk, where you don't really know what's going on mystery-wise, until it's suddenly revealed something sinister was going on, based on clues that seem very vague at first. The revelation in Tomurai Tetsudou is brilliant, and really dark, and I can definitely see why it was selected for publication. Cleverly plotted, and theme-wise very, very memorable.
Sonoda Shuuichirou is an author who is featured in several of the (Shin) Honkaku Suiri volumes, but he never made a major debut as a professional writer, nor have his stories been collected in a single collection. I suspect he was a Kyoto University Mystery Club member, but am not 100% sure. I loved the story I read by him in the last Shin Honkaku Suiri anthology, so I was very curious to see what the story in this volume would be about. Dokusha Yo Azamukarurunakare ("Reader, Don't Be Fooled") starts with a segment where the narrator Sonoda discusses Chesterton's The Invisible Man with his friend Kurashina, a huge mystery buff who thinks very little of the trick of that story. When challenging Kurashina to come up with something better himself, Kurashina admits he already has a similar, but better idea in his mind, and soon after, Kurashina presents Sonoda with a whodunnit script with a Challenge to the Reader, explaining his story tackles the same themes of The Invisible Man, and challenging Sonoda to find the culprit.
The story-within-a-story is set at the building of the Engineering faculty of a university. It's the last day of the academic year, so the building is nearly empty, as classes have already ended about a month earlier and there are only a few professors here and students working on projects with those professors. That is why one of the two guards of the building finds it weird when a humanities student enters the building. Shibata Hirotaka has a student ID, so he can walk in freely of course, but he can't shake the feeling something's off, which seems confirmed when his co-worker mentions he didn't see Shibata when making his rounds, even though they have no record of him leaving the building. The guard makes another round, making sure to check who is in what room. He's at the third of the fourth storey, when he hears the alarm that goes off when a window is opened. He realizes it comes from above, but the next moment, he hears a loud crash, and he already knows what's happened: when he arrives at the open window on the fourth floor, he looks down and sees Shibata lying on the ground below. The police come questioning everyone in the building, and three of the students turn out to know Shibata from their theater group, but it appears they have a perfect alibi, so then who is the killer?
Well, I sure give it to Sonoda: this was an interesting take on The Invisible Man, a killer who is visible in the story, but also not. It only works if you make a very rigid assumption regarding how people talk, but I think it works here and it is absolutely fair. If you assume this story is 100% fair to the reader, then the method with which the killer is hidden works absolutely, but if you have even the slightest doubt about that, this story might feel unconvincing. As a whodunnit with a Challenge to the Reader though, it works, and that means I will have to read those other Sonoda stories that were included in these anthologies too, because that's two good stories out of two read now...
The final story I'll discuss this time is by Ooyama Seiichirou, and this is kinda technically his debut work, I guess, as this was the first story by him that got published in a 'proper' publication. His "author introduction" literally just says this is the first time he got selected. Saint Dionysus no Puzzle ("The Puzzle of Saint Dionysus") introduces us to the narrator (a detective writer), who is the Watson to Sakaki Kousuke, a private detective. Sakaki is asked by Kobayakawa Masatsugu to bring his sister back home: she is a member of a cult run by Kurusu Tokuzou, who thinks he's the reincarnation of Saint Dionysus (Saint Denis of Paris). The sister is actually one of his grand disciples and Kobayakawa tells Sakaki Kurusu and his grand disciples are currenlty staying on an island, marking the perfect opportunity to get to her, as she's usually in one of the well-guarded facilities of the cult. He suggest they use an inflatable raft to make their way there and rescue his sister. Sakaki and the narrator do as suggested and make their way to the island, but are immediately found by guards. The sister hysterically cries she has enough of her brother, and that she's here by her own free will. Sakaki and the narrator are thrown in a cell for the night, but the following morning, the grand disciples bring shocking news: Kurusu has been murdered! The head of the cult was found in the Meditation Chamber, with his head cut off and placed in his arms, just like Saint Denis of Paris. The grand disciples ask Sakaki to figure out who the murderer is: it has to be one of the grand disciples, as the lower-rank members all sleep together, there were guards making sure nobody would enter the island, and Sakaki and the narrator were locked up. Meanwhile, the remains of Kurusu are placed in the Heavenly Chamber, a private room for meditation for the head of the cult, set up at the highest point of each of the cult's bases. Sakaki and the narrator interrogate the grand disciples, of which none seem to have a good alibi for the night. The following morning, shocking news arrives again: the body of Kurusu was found in the Meditation Chamber again, holding his own head in his hands. Did he walk out of the Heavenly Chamber after being decapitated, just like Saint Denis of Paris? If not, why was his body moved?
A story with a very cool set-up with the cult and the ties to the story of Saint Denis of Paris, and while it might sound obvious now, but as this was Ooyama's first published story, I guess readers back then couldn't have known Queenian problems would be one of Ooyama's trademarks. And yep, we have that here too. While a tale about a corpse that leaves a room and walks in the night could easily have focused more on the horror or seemingly impossible aspects of the problem, Ooyama here focuses on the conundrum as a logical issue: why was the body and the head moved? The solution is of course brought by a logical process that focuses on the actions the murderer took and the motives behind it, and while the basic idea is pretty simple, it is a deliciously Queenian approach to the set-up, and I like the story a lot. I have a feeling Ooyama "now" would have planted more physical clues to facilitate the trail to the solution, but it's still very solvable while also making clever use of the story behind Saint Denis.
Anyway, these were only three of the eight stories in Shin Honkaku Suiri 3, but I enjoyed all three of them a lot, so I'll try and get around to discussing the remaining five stories in the future. I probably should try read more of the (Shin) Honkaku Suiri anthologies anyway: I have only read about 1.5 volume, but the quality of the plots is generally really high, and if all 20+ volumes of this series retain that level...

Remember to Ring Twice
I always think of white and blue when I think of the covers for the Koigakubo Academy books, even those are not even the primary colors for every cover...
Disclosure: I translated Higashigawa Tokuya's Lending the Key to the Locked Room. If you haven't read it yet... read it!
Higashigawa Tokuya first introduced his readers to the fictional school of Koigakubo Academy, located in Kokubunji, Tokyo, in 2002 with Manabanai Tantei-tachi no Gakuen. In that book, we followed the members of the Koigakubo Academy Detective Club as they tackled a murder case that happened at school. After the first book about the Detective Club, we have seen other books featuring the Detective Club too, but interestingly enough, Higashigawa also started to feature the high school in other books that weren't about the Detective Club exclusively. First we had the Kirigamine Ryou series, which featured the vice-president of the Detective Club who for some reason very seldomly met the characters of the main series, but still often came across mysteries herself. Four years ago, Higashigawa wrote Kimi ni Yomasetai Mystery ga Arunda, a wonderful short story collection about the Second Literature Club of Koigakubo Academy. And 2024, the twentieth anniversary since the first book with the Koigakubo Academy, brought us another new series about the school where so many odd happenings happen, both criminal and not. The binding element between all these series is the school itself, with some characters like the teachers or a delinquent student appearing in several series, while usually the main characters of each series remains in their own 'part' of the world.
Asahina-san to Himitsu no Aibou ("Miss Asahina and the Secret Buddy", 2024) is a short story collection which presents us with another detective character in the school: Asahina Reika is the daughter of the school's chairman, which basically gives her a lot of informal authority. That is why some students sometimes go directly to her to ask for help when nobody else can help them: Asahina is actually quite involved with the school's reputation and how it's run, and basically acts as a 'shadow chairman' under the auspices of her father. That is why Ishibashi Mamoru comes to her when he's accused of theft by his fellow Mystery Club members: one morning, Ishibashi was the first to retrieve the padlock key from the teacher to open the club room. When he noticed one locker door was open and approached it, the harm had been done: the user of that locker saw Mamoru standing in front of it, and it turned out a manuscript for a detective story he was writing, had disappeared from the locker. He had put it in the locker the day before, and other members were present when they all left the club room together, put the padlock on the door and returned the key to the teacher. This means nobody could've gained entry into the club room and stolen the manuscript from the locker, until Ishibashi asked for the club room key this morning. Mamoru swears he's innocent, and wants Asahina's help, who's secretly more than thrilled, because she's a huge mystery buff and realizes she might be dealing with a genuine locked room mystery. Her guesses however are shot down very swiftly, and it seems Mamoru won't be able to escape the shadow of suspicion, until Asahina accidentally slaps Mamoru in the face, and he.... turns into his deceased brother Wataru! For some reason, Wataru's personality takes over each time Mamoru's slapped in the face. Wataru's a lot sharper than Mamoru and Asahina, and he quickly solves the case of the theft, even though Mamoru seems not to be aware of Wataru taking over his body and has no recollection of solving the case (he thinks Asahina did it). Asahina and Mamoru/Wataru's paths cross more often, and their encounters only make Asahina more interested in Mamoru and Wataru's odd relationship.
The first tale, Meitantei, Misshitsu ni Arawaru ("The Great Detective Appears in the Locked Room"), introduces us to the main characters of Asahina, Mamory and Wataru, and also shows a bit of Koigakubo Academy's Mystery Club, which we have seen previously in the second Kirigamine Ryou short story collection. The problem involves a theft from a club room: the club members all saw how the manuscript was left in a locker in the room and they left the room together, saw how the padlock was put on the door and one of them returned the key to the teacher in charge. The key is specially made and can't be copied, and the teachers keep club room keys in a room with camera surveillance, so it appears only Mamoru, who took the key the following day, could've stolen the manuscript in the morning. Asahina presents a few fairly simple theories which are discarded fairly easily, which is perhaps also why the actual solution to the conundrum is also fairly simply: this solution is basically of the same level Asahina could and should have presented herself, and should've been shot down too. So to have the mysterious Wataru appear only to point out a simple solution....
Satsujin ga Misui Datta Hanashi ("A Story About an Attempt at Murder") starts with Asahina hearing the shocking news a student of Koigakubo Academy had been assaulted the previous night. The girl had been to a concert of Tamaranzaka 24 and had been on her way home, crossing a grove near the station, when she was attacked and stabbed in her stomach. She was found by a classmate who quickly called the emergency line. Because the girl's a classmate of Mamoru, Asahina decides to use him as her Watson to learn more about the case. They visit the mother of the victim, and learn the daughter didn't quite get along with the mother's boyfriend, but he has an alibi for when the girl was assaulted. While the actual truth behind why the girl was attacked is not very surprising or original on its own, I love the deduction chain Higashigawa laid out for the reader. The clue that leads to the revelation of how it was done is really good, and expertly hidden, and easily one of my favorite clues of the whole book.
Asahina Reika is the honorary student council president, which means she supervises the board meetings once in a while (when she feels like it), and the other members just have to dance to her tune. the day after another meeting, Asahina visits the board office to use her locker there, when she notices a window was left open. She then realizes someone has moved some of her books in her locker, so she summons Mamoru (and Wataru) to help her find the insolent person who dares go through her stuff in Seitokaiyakuinshitsu no Koubou ("Offence and Defence in the Student Board Office"). After a good slap, we see Wataru's observations of a few clues that ultimately lead Asahina and Wataru to a rather surprising discovery, which shows there was something far more sinister going on in the student board office than just a theft. Not a huge fan of the story to be honest: the first half the mystery-solving is more focused on reverse-engineering Wataru's deductions about the intruder's actions, rather than doing that ourselves and in the second half, we investigate a mysterious message that... probably would have been more interesting in a visual medium, but not in a prose form.
Tenshi wa Poolside ni Ukabu ("Angels Floating at the Poolside") is set during a summer evening: students are still around at school because of two events: geography teacher Ikegami is supervising a group to watch the stars (she herself is actually a huge believer of UFOs), while another group of students are playing night baseball on the school grounds. A guard meanwhile is making his rounds, when he senses something's wrong with the school's pool. While the fence is properly locked and barbed wire ensures nobody can climb inside (or as some swimming club members say, it's to prevent members from fleeing training), the guard still can't shake the feeling someone is inside, so he unlocks the pool gate and has a look around. His attention is drawn to one of the diving boards, so he climbs the ladder. He's nearly at the top when he suddenly feels something hard hit his head, and he falls of the ladder, hits his head on the ground and is knocked out. But just before he passes out, he's sure he saw a winged angel flying in the sky above him... The guard is later found by students passing by. Asahina of course can't help herself and decides to investigate herself (with Mamoru/Wataru as her Watson). This is another story where I think it would've been better had it been created in a visual medium. While I think the solution on its own is okay, I think asking the reader to deduce it based on the hints is a bit too much, while it would've been much more natural if the story had been told in a visual format. The attack on the guard (which is kinda impossible because he was hit on the head while climbing up the ladder and he didn't see anyone on the diving board before he was knocked out) is connected well to the guard seeing floating angels, but it's still a story that has trouble feeling really satisfying.
The final story, Chashitsu ni Kieta Shoujo ("The Girl Who Disappeared In the Tea-Ceremony Room"), has Asahina wondering whether he should tell Mamoru about Wataru taking his body over each time he's hit on the head, but before she can make a decision, she and Mamoru stumble upon a new case, and a very personal one too: Asahina sees a brown-haired girl rummaging through her desk in the classroom! Asahina and Mamoru give chase, and they eventually find the girl running into a remote part of the campus, which is walled off and ends in a cul-de-sac where the tea-ceremony room is, a small building used by the tea ceremony club. Mamoru is sent inside the room by Asahina, but it appears there's only a tea ceremony club member inside, who is far too tall to be the girl Asahina saw. A swift look across the room also shows there's no place for the brown-haired girl to hide inside. Asahina then decides to check behind the tea-ceremony room too (she makes sure Mamoru goes the other way around the building), but they only find a delinquent student trying to smoke in secret. But as this part of the campus is completely walled-off, how did the girl escape if she's not in the tea-ceremony room nor behind it? Impossible disappearances are pretty much a staple of the mysteries set at Koigakubo Academy, as other books also feature them (especially the Kirigamine Ryou series), and even with that in mind, I'd say this is a pretty good story. The solution is very simple, but also quite clever: it would have been pretty interesting on its own as it makes good use of the unusual setting, but Higashigawa manages to tie a very unique clue to it too, giving it another level of depth. Just don't come here expecting some real resolution regarding the Mamoru/Wataru plotline.
Overall though, I'll need to be honest and say that Asahina-san to Himitsu no Aibou is probably my least favorite short story collection set at Koigakubo Academy until now. I love the Kirigamine Ryou stories with the overly-enthusiastic Kirigamine and the weird disappearances and other impossible crimes(?) she encounters, and I was really surprised by how fantastically Kimi ni Yomasetai Mystery ga Arunda was set-up with multiple meta-level stories, but in comparison, the plots of Asahina-san to Himitsu no Aibou seemed a lot simpler, with less finesse going on in regards to how the mysteries were planned. And I guess I never got really invested in the Ranma 1/2 / Touch-esque subplot of Mamoru and Wataru (hmm, now I think about it, it does have a Shonen Sunday vibe to it), so that wasn't really something that kept me interested. I'm always in for more stories set at Koigakubo Academy, and it was fun seeing familiar faces pop up in the background, but I guess I did expect something more 'grand' for the twentieth anniversary of the setting. Let's hope the next one is more memorable.
