"Seven Days A Week" (George A. Robertson Jr.)

I usually have a lot of posts scheduled months ahead, so whenever I read a newly released book and decide to push a review early to keep it timely, it messes up the whole schedule...

It is a late July day when Kuroba Uyuu wakes up in a hospital room, looking down at a somewhat familiar person lying in a bed in the ICU. He recognizes the face.... as his own, and when he sees he's floating and he himself is in a semi-transparent state, he starts to realize that he is in fact a ghost. He realizes the nurse can't see him either, and follows her as she reports to the doctor that her patient (Kuroba) has stabilized after a cardiac arrest earlier this morning, but that he's still in a coma. It's then that Kuroba slowly remembers what happened to him. Four months ago, on White Day (March 14), he was out on the roof of his apartment building, when someone pushed him from behind. Kuroba ended shish-kebabed on the statue of a dog holding a toothbrush high up in the sky beneath the building. It is then he recalls he had an appointment for that evening to meet a prospective client and the realization he never made it there annoys him a bit, as trust is an important factor in his line of work. For Kuroba was going to meet his client as The Perfect Crime Contractor: Kuroba has been active in the underworld for almost a decade as someone whom people can turn to if the justice system fails them. He exacts revenge for his clients, usually in a manner that mirrors the way the criminals hurt their victims, like swindling swindlers or putting the police on the trail of the serial Topsy-Turvey Killer and cornering him into a certain death. The Perfect Crime Contractor of course executes his revenge in a way that safeguards both himself and his clients, hence his nickname, and while the police knows of him, they never have been able to prove for example his involvement in certain suspicious deadly "accidents" that happened to some murderers.

Having nothing to do as a ghost, Kuroba floats to the place where he was supposed to meet his clients four months ago: an abandoned house in the outskirts of the city. When he arrives there, he is suddenly attacked by a young girl, or at least, she attempts to, but she walks right through him. It turns out the girl can actually see ghosts and has seen a few before in her life. The girl is Otoha, and she is the daughter of the clients Kuroba was supposed to meet on the fourteenth of March. However, they were found killed in gruesome manners in this abandoned house the following morning: both her father and mother had been poisoned, and her father was then hanged upside-down from the ceiling. However, it was a snowy day, and there were only the footprints of her parents leading into the house, and none out (of the killer), meaning it was a double locked room murder: this is why Otoha has been coming every night to the house, as she learned her parents were going to meet the Perfect Crime Contractor here that night and she believes he killed them with a perfect crime. After Kuroba explains he's the Perfect Crime Contractor, Otoha realizes he can't be the killer of her parents: Kuroba being stabbed on the statue had of course been all over the news, and his fall occured hours before her parent's deaths. Kuroba's fall has been filed as an accident by the police, but Kuroba can't believe his fall, and the murders on Otoha's parents are disconnected as they happened just within hours of each other. Otoha pleads with Kuroba to help her exact revenge on the murderer of her parents, as that's probably also the person who pushed Kuroba off the roof. As a ghost, Kuroba can't directly interact with the physical world, and he also learns from Otoha ghosts can only roam for a maximum of seven days before they fade away completely and reluctantly, Kuroba agrees to help Otoha in tracking the killer and mentoring her so she can take her revenge, but in a way that will keep herself out of harm's way. Can this unlikely duo accomplish their revenge before Kuroba's ghost will disappear in seven days in Houjou Kie's 2024 novel Shoujo ni wa Mukanai Kanzen Hanzai ("An Unsuitable Perfect Crime for a Girl").

Yes, as a Houjou Kie fan since her debut, I of course read her latest book the moment this was released (it was released last week). After debuting via, and writing three excellent novels for publisher Tokyo Sogensha, writing the exciting short story collection Amulet Hotel at Koubunsha, we now have Houjou Kie's first novel via publisher Kodansha (you may remember a few weeks ago I did review a short story she did via Kodansha's Mephisto Readers Club). So a different publisher, but as always, we see Houjou do what she's best at: presenting densily plotted mystery novels featuring a special background setting, in this case, we have the existence of ghosts. Which is funny, because I only read one story by Houjou from when she was still a member of the Kyoto University Mystery Club, which also featured a ghost. Also interesting to note is that the editor of the book was also a former editor-in-chief of the club.

As I am writing this, I have to admit I find it difficult to sort my thoughts on this book. Not because it's a chaotic book, but I think I can best explain it by first pointing out that based on her social media, it does appear Houjou very much likes television drama and films and in a way, Shoujo ni wa Mukanai Kanzen Hanzai feels very much like a full season of a mystery drama series. A lot happens in this book, and basically each chapter turns things around or focuses on a different main problem, even if everything is surprisingly neatly connected. We start out with an impossible crime: the murder on Otoha's parents in a house with no footprints in the snow leading to the entrance, but Kuroba and Otoha's investigation lead them to more mysterious crime scenes and events: some might be "classic" crime scenes like the one mentioned above, or a more open crime scene like the rooftop from which Kuroba was pushed, while others focus on other mysteries like an impossible situation where a person manages to conjure a weapon out of nowhere despite security precautions, or "impossible situations" where the young Otoha needs to escape a trap without being detected. The book is crammed full with mysteries upon mysteries, but they all flow into each other in a very natural manner, as part of the duo's investigation, and because of that, it really feels like a complete series, rather than a single novel.

This is also because of the insanely densily-clewed plot. While the story has you following many different situations one after another, Houjou somehow manages to hide all her clues and foreshadowing across the whole novel, rather than compartmentalizing all the clues together with the stiuation they correspond too (as in [part 1 + clues of part 1] -> [part 2 + clues of part 2] etc.). The result is a very satisfying mystery novel, where everything you read can turn out to be a clue that might be relevant to a situation you have already read about.... or about that might still come, and those situations themselves might be completely different mysteries. I can't even imagine how difficult it must have been to keep track of all the clues during the writing process, keeping an eye on when and where each clue was employed or when foreshadowing would be necessary. Houjou has always been a very dense writer when it comes to clues, but due to the set-up of Shoujo ni wa Mukanai Kanzen Hanzai, with a series of mysteries set in motion by different actors occuring across city, rather than a series of murders by the hand of one murderer happening in an isolated setting like in the Ryuuzen series, you become even more aware what an amazing plotter she is, as clewing all of these situations and intertwining all these threads must be hell as a writer.

At this point, I haven't even really mentioned what makes this book truly amazing. So by now, we basically have a television drama season's worth of mysteries, all with intertwined threads of clues and foreshadowing as we follow the unlikely duo of a primary school child and a criminal ghost trying to find a killer and take revenge on them, but... this is also a book that focuses on multiple solutions, in the tradition of Christianna Brand, Ellery Queen and Anthony Berkeley. Otoha, as a young child, is being mentored by Kuroba's ghost and being taught the ropes of how to deduce, a skill extremely important when it comes to planning out perfect revenge plans and soon the two find themselves bouncing off deductions off each other about the various mysteries they encounter during their investigation. In some rare occcassions, we even have other character offer false solutions too, and what makes this so memorable is of course due to the fact I mentioned earlier about how insanely many clues are found throughout the book: all of the false solutions presented in the book, as well as the real solutions, are of course all properly clewed (and the false solutions of course feature clues that will ultimately prove them false). The realization Houjou had to keep track of all of this is honestly just stunning, and the result is an incredily fun mystery novel, as it always keep you guessing, by constantly shifting the mystery you're thinking about and by challenging the reader into finding the real solution among the many false solutions she planted. Some of the major mysteries, like the initial locked room mystery, even have like three or four different false solutions presented, so it's an extremely tricky story.

With so many mysteries going on, it's understandable that some mysteries are less memorable when taken on their own: there's a minor no-footprints-in-the-mud situation halfway through the book for example that has a rather basic solution, and while I like the concept behind the weapon appearing out of nowhere, I feel it needed one more clue to feel truly fair, but that's nitpicking, as the way all of these are put together is impressive enough, and I do really like the solution to the first no-footprints-in-the-snow situation, as well as the great way in which Kuroba and Otoha initially figure out a logical connection between Otoha's parents' murderer and Kuroba's assailant. I also think readers will appreciate the time Houjou allows the reader to spend with both Otoha and Kuroba: they are explored more deeply than any other character in Houjou's earlier work and that is probably also a reason why this book feels so much like a full season of stories, rather than a single installment. I do think personally that the ghost aspect of the story feels less intertwined with the mystery in this book, compared to how Houjou's earlier work utilized their supernatural/unusual elements: Kuroba can't interact with the physical world, so he mostly mentors Otoha and can act as an extra pair of eyes and ears, as well as provide information Otoha can't have, but there's less of the "make super clever use of the rules of this specific supernatural element" we have seen in her previous novels. Oh well, you can't have everything.

Because even with that minor point, I do think Shoujo ni wa Mukanai Kanzen Hanzai is one of the best mystery novels I have read this year, and easily so. It's a very satisfying read as it covers so much ground and throws Otoha, a young, indepedent cheeky girl, and Kuroba, a ghost with a chip on his shoulder, in so many mysterious situations and allows both of them to show both their best and their worst as they try to find the killer and formulate a way to exact revenge on them. A must-read of this year!
