So I got a signed copy of this book, which is cool, though it was a bit disappointing that while I preordered the book to have it signed, it didn't arrive until a few weeks after the book already released, and some bookshops *also* carried copies that were signed.
After his parents passed away, Sakoto Yasuyuki inherited several buildings his parents rented out, and he has continued managed these properties since, meaning frequent visits to his properties to check up on maintenance and if necessary, chat with his tenants. One of the tenants he's got to know fairly well is Mrs Unabara, which is actually quite unusual. While Unabara is known in the block as someone who keeps to herself, she's been quite friendly with Yasuyuki ever since his parents died, checking up with him and occasoinally bringing sweets. Which is why he becomes quite worried when he receives a message on a phone from her saying she's grown tired and that she'll go to another place. After asking around, it turns out Unabara has not been seen by her neighbors for over a week. Because it does sound like Unabara might have ended her own life, Yasuyuki decides to check out Unabara's apartment, where he finds clues that indicate a certain property somewhere in the middle of the Gunma Prefecture mountains that belongs to one of Yasuyuki's parents' friend: because this friend isn't in the country, his parents had been taking care of the property. Curious as to why Unabara would have known about this place, and with have no other clues left, Yasuyuki and his girlfriend Saori decide to combine work with pleasure: they're going on a short road trip, and swing by the property just to see if they can find any trace of Unabara.Following the crudely-drawn map they found in Unabara's room, they eventually find a hidden dirt path that leads into an enclosed opening in the mountains, where the property stands surrounded by cliffs: the only opening into this 'basin' is guarded by a fence, and beyond it, they spot three small buildings. They park their van and check out one of the buildings, when they are suddenly held captive by a group of people, whom unfortunately, they recognize: each of them is a wanted criminal, some for murder, some for arson and other violent crimes. They soon learn that Mrs Unabara, knowing the property's owner wasn't in the country, had taken the property over, offering it as a safe haven to these criminals on the run. For personal reasons, she had been bringing supplies regularly to these people, who now live a secluded life, confined to this property, but at least in freedom. When the criminals learn that Mrs Unabara has disappeared and might even have committed suicide, they become very distressed: she was the only person capable of bringing them food and other supplies, as they can't risk stepping even a step outside their haven. Yasuyuki suggests he and Saori will from now on bring supplies and keep their secret, in exchange for their freedom, but of course, the criminals won't just believe them on his word. Which leads to a horrible compromise: the criminals agree to let Yasuyuki and Saori free and have them supply them with food, if they kill one of the criminals and record their own crime! This proof will act as an insurance that Yasuyuki and Saori will do as promised and not sell them out to the police, as they will all be murderers anyway. The group give Yasuyuki and Saori relative freedom and promise to not move too much as a group, as to allow Yasuyuki and Saori to pick any target they want. Will Yasuyuki and Saori be willing to take someone's life to escape this criminal's paradise in Yuuki Haruo's 2026 novel Rakuen ("Paradise")?
Rakuen is the long-awaited third entry in Yuuki's series of biblically-titled, closed-circle mysteries, following Hakobune ("The Ark") and Jikkai ("The Ten Commandments"). While the events of the three books are not directly connected and you could read them in any order, the books do form one series, with a subtle thread connecting them. As mysteries, the three novels also follow similar set-ups and themes: the books all revolve around closed-circle situations, where a group of people, who mostly don't know each other that well, end up stuck in an isolated location (an underground shelter in Hakobune, an island in The Ten Commandments and a mountain basin). These people are then tasked with an ethical problem, while dealing with murders: in Hakobune, escape from the slowly flooding shelter is only possible if one person sacrifices themselves to open the door for the rest. In Jikkai, the murderer tasks the rest with ten rules that force them to actively not investigate the murderers happening on the island. And in Rakuen, we follow Yasuyuki and Saori, who are given the task to kill someone if they want their freedom: with the "excuse" being that all the potential victims are in fact wanted criminals who are responsible for at least one death.
Of course, that isn't the whole story, as it wouldn't be much of a mystery novel if the problem was just about Yasuyuki and Saori discussing what they should do. The first third/half of the book is a bit slow, as we first get introduced to this initial conundrum, and then Yasuyuki and Saori are given relative freedom: while the gate to get out of the basin is kept locked, they get their own place in the shed and given some tools and a camcorder, and the rest of the group intentionally spend their days mostly seperated from the rest, all so Yasuyuki and Saori can observe them and then pick one of them as a target. Of course, it is not easy to decide to kill another human being, so the first few days, Yasuyuki and Saori just spend their days observing the others, without real intention of killing any of them. They do start to learn more about the people who are staying in this "paradise", and about the circumstances that led each of them to commit the crimes they commited. Some people might even appear sympathetic, though of course, Yasuyuki and Saori are never sure whether it's not just an act just to make them less inclined to pick them as a victim. However, things change when one of the people is indeed murderered... but Yasuyuki and Saori deny having commited the crime! Which of course means that one of the others committed the murder, though everyone denies having committed the crime. Days pass by, and more murders are commited, which only puzzles Yasuyuki more and more, for what reason could a murderer have to be committing these murders now, while Yasuyuki and Saori are also tasked to commit a murder?
While a few murders occur during this tale, don't expect too much surrounding the mystery of how of these deaths: while there are some questions about the individual deaths, like a situation that appears to be a locked room murder, and situations where everyone might have an alibi, what Yuuki does here is adequate, but nothing memorable on their own (i.e. no particularly original locked room or alibi trick being pulled off here). That said, I still immensely enjoyed this book, because the whole book is written around a theme and the conclusion, and here, Yuuki does a great job. As the story unfolds, a nasty thought might slowly start creeping into your mind, and it only grows and grows. By the time you get to the conclusion, you might think you're already mentally braced for what is coming, but then Yuuki far surpasses your expecations/fears, unveiling the horrible truth behind the title of this book and the true meaning of what a safe heaven is for those living there.
Here is where the book shines, as Yuuki unveils his excellent plotting here, with oh-so-many clues and little giveaways planted throughout the story. Whereas a mystery novel, naturally, often focuses on planting clues to explain each individual murder/mystery, in Rakuen, those are not nearly as memorable as the clues/foreshadowing that are used to build up to the conclusion that deals with the overall theme of the book, rather than the seperate murder elements of the story. A book like Hakobune had more interesting murder situations that I could discuss on their own, which is sadly not really the case here, but Rakuen still has a very strong overall story/thee that is properly build-up as a mystery story. I wonder if this is the last book Yuuki will write in this specific series, as it does work wonderful as an ending to the three books.
In general, I think Rakuen might feel smaller in scale in terms of mystery compared to previous two books, but it is a genuine page-turner, initially focusing more on the internal conflict regarding the task set upon Yasuyuki. However, it becomes a truly memorable mystery novel once we get past the individual, less interesting mysteries and we move towards the climatic conclusion that leads to escaping paradise. Thematically, the book is absolutely great, and the actual structuring of the mystery surrounding the overall theme is done as expertly as we can expect from Yuuki, who has been around as a writer for some time by now. So definitely a recommended read, and a no-brainer for those who have already read the previous two books. It quite easily ranks among my favorite reads of this year! And now we see if this ever sees a follow-up or not!
