Blood Will Tell

 "It's in my blood. I can't help it."

"Mrs. McGinty's Dead"

Which such long times between my reviews for both Detective Conan and the Kindaichi Shounen franchise, perhaps I should find a third manga to do regular reviews of...

Hajime's cousin Fumi was a focus character in The Kindaichi Fumi Kidnapping Murder Case, the final case in Kindaichi Shounen no Jikenbo R ("The Young Kindaichi Case Files", 2013-2017), for the moment the last series in this long-running franchise still set in Hajime's teenage years. Part of the fun of the currently running series Kindaichi 37-sai no Jikenbo ("The Case Files of Kindaichi, Age 37"), set many years later, is of course not only seeing how Hajime has changed (or not) in two decades, but also to see what happened to the other main characters, so there were probably quite a few fans who were interested to see what had become of that young, bratty girl who at times would show that she too was one of the talented grandchildren of the legendary detective Kindaichi Kousuke. Fumi finally returned in volume 9 of the series, first released in April 2021. I already wrote a little about the story that started in that volume, but The Ayase Serial Murder Case wouldn't be concluded until volume 11, which was released in October 2021, so it took a while for me to finally be able to write about this rather lengthy story. 

Blood will tell, so should it surprise anyone that the twenty-nine year old Fumi now works at a detective agency? In her spare time though, she's also dabbling with mystery writing, and she's finally making her professional debut by winning in one of the categories of the Osokawa Mystery Awards with her novel The Hinokawa Legend Murder Case, written under the pen name Kaneda Hifumi. Hajime is of course happy for his cousin, but perhaps even happier he managed to secure the organization of the award ceremony for his company. At the venue, Hajime and his assistant Marin meet Osokawa editors, fellow debuting winner Fuyuki Agatha and Fumi's boyfriend Yuuto, an accomplished mystery writer himself. The grand winner of the main award is Setokura Ryou and his The ABC Murders-inspired The Ayase Serial Murder Case, but Setokura disappears during the ceremony, and instead a creepy video is shown on the projector, showing a man being murdered inside an abandoned building in a city block named Ayase. Hajime quickly realizes that this murder is exactly the same as the first murder in The Ayase Serial Murder Case, that's about a series of murders in city blocks called Ayase. Because there's no proof of an actual crime, Fumi and Yuuto decide to go look for the building shown in the video themselves while Hajime tries to convince Inspector Makabe to do something. Fumi and Yuuto, as well as some other interested parties manage to locate the building and find a corpse there. But when a new murder video set in a different Ayase is mailed to Setokura's editor, everyone fears the copy-cat killer will continue with these Ayase murders and it's up to the two grandchildren of Kindaichi Kousuke to catch the murderer.

While Detective Conan has a very irregular publishing schedule nowadays, Kindaichi 37-sai no Jikenbo has been rather consistent in its releases, so you don't get gaps of a year between volumes. Still, the stories in this series seem to take up more chapters than they used to be, so this is not the first time a story has been spread across three volumes. It takes about half a year to release three volumes normally if there's no delay, so still better than the year wait between Detective Conan volumes 98 and 99, but still, three volumes is pretty long for a serialized story and I can't say that I'm a big fan of that. I know a lot of the fans of this series prefer the longer format, one of the defining differences between this series and Detective Conan, but as I'm reading this volumes as they release, it's just so frustrating to see a story cut up in so many volumes...

But that's more a matter about the publication format than the story itself, let's get back to that. After The Poltergeist Manor Murder Case and The New Murders At The Foreigners Hotel, two not very impressive stories, I have to admit I liked The Ayase Serial Murder Case a lot more, even if as a detective story, it's not going to be very surprising or hard to figure out the major mysteries. I still enjoyed it a lot, partially I think because we actually get to see a lot of Fumi doing her own detecting now. The story is not solely focused on Hajime as the only detective, and Fumi, as a detective's assistant, mystery novelist and granddaughter of a rather well-known detective, gets to do a lot too. She's not as smart as Hajime, but that brings a different dynamic to the story we don't usually see in this series: while we'll see rival detective figures at times in the form of people like Superintendent Akechi, Fumi is unique in this series as an ally character, and this allows The Ayase Serial Murder Case to develop as a story from multiple angles and it feels rather fresh. I would love to see this Fumi more in the series: in the original series you'd catch glimpses of her talent in certain stories, but she was really by far the youngest character in the cast, which made usage of her sometimes a bit difficult in stories. Here she's really grown into a fuller character who could support her cousin in more interesting ways than we had seen before in this series.

The story starts in a real-time thriller mode, with Hajime, Fumi and the others realizing someone is copying the murders from the novel The Ayase Serial Murder Case, meaning first someone whose name begins with "A" will be killed in a place called Ayase, and then someone whose name starts with (the Japanese kana) "YA" in a different Ayase, etc. and a lot of the story focusing on them actually locating the crime scenes and trying to stop the killer in advance. As the story develops however, Hajime starts to notice little things that seem to not follow the book, and his attention is also drawn to the victims themselves, and it doesn't take long for him to deduce what of course most readers would have guessed: these are not random murders that are "just" copying a novel. By the time Hajime starts looking back at all that has happened and tries to figure out what is hidden beneath the surface of the case however, the story is severely handicapped by the series itself. For most people will be reading this series, because the franchise has always focused on impossible crimes. It's extremely rare for this series to have a story not focusing on an impossible crime, so when you know there's no locked room murder here or some murder without footprints, 99% of the readers will guess that this is one of those stories that focus on the murderer having a perfect alibi. And that means that everyone will at least have an idea who the killer is going to be, because there's basically only one character whose alibi is strong enough to be considered "perfect". And from that point on, all you're going to do is to pay attention to everything they do in each panel and you'll soon get a good idea of how the whole thing was pulled off.

Other series might have gotten way with this, but I'd argue that Kindaichi Shounen is the one mystery manga where it becomes too apparent immediately. While this franchise is never about the whodunnit only, once you know who to watch, a lot of the relevant panels will stand out a lot and because the underlying mystery plot ultimately uses fairly simple tricks (though woven into each other to make the overall picture more complex) to create the seemingly iron-clad alibi, it's rather easy to guess most of what's happening. That said, I have to admit the last act of The Ayase Serial Murder Case did manage to turn my initially somewhat lukewarm views on the story into something more positive. There's a great part in the story where Hajime decides to confront the suspect despite not having found any evidence yet, resulting in a very amusing game of shadows, where Hajime tries to lure the culprit into traps, while they carefully weigh each of their answers and tries to turn things around. The scene is tense and exactly because the reader will also have noticed a lot of the little questions Hajime asks, it's pretty interesting to see the suspect addressing them directly and trying to divert suspicion from themselves in a rather convincing manner. When Hajime finally manages to seal the deal with the support of both Makabe and Fumi, you'll realize the murderer was definitely one of the more trickier ones Hajime has encountered, which makes the moment Hajime reveals they were suspecting them right from the start even more satisfying: this moment is actually quite clever and I had completely missed the clue that set Hajime on the right trail at the start of the story. The story also ties back to the overall storyline of this series about Hajime slowly being drawn back into the life of an amateur detective again and about the incident that had made him stop in the first place, planting seeds for later story developments.

Volume 11 ends with the opening chapter of The Killer with Twenty Faces, about an Edogawa Rampo exhibition and a rather familiar-sounding name, but I'm going to guess that that story will also be spread across three volumes, so I'm guessing I won't be discussing it until the early summer of the northern hemisphere...

So The Ayase Serial Murder Case might not be an exceptional high-point in terms of mystery plotting in Kindaichi 37-sai no Jikenbo, and the execution of the story in fact suffers a bit because it's this specific series, but on the other hand, I think fans of the franchise will enjoy this story exactly because it also feels a bit different in the way it presents the story, with fan-favorites like Fumi returning as an adult, as well as a rather determined murderer who is able to keep up a good fight with two grandchildren of Kindaichi Kousuke. After a story set specifically at the location of an older story, and a story that followed the familiar closed circle trope, the pacing of this story felt refreshing despite the core plot being fairly predictable. And I'm kinda looking forward to seeing The Killer with Twenty Faces unfold: it's been a while since we had a killer who dresssed up in a costume in this series!
