Prediction: Murder

Six little Soldier Boys playing with a hive

"And Then There Were None"

For some reason, after reading the prologue, I thought this book would be difficult to read in terms of writing style, but I ended up finishing it in about a day...

After continued harrassment by his boss led to a suicide attempt which fortunately was foiled by Sousaku's father, Sousaku returns to his hometown to recover. His childhood friend Jun of course tries to help Sousaku, as does the third friend of the group, Haruo. They decide to go on a trip together, and Haruo suggests going to Mukui Island, a remote island in the Seto Inland Sea. Mukui Island advertises itself as having nothing to offer and it's only inhabitated by elderly people, with all the young people having moved away from the inconveniently located island long ago. The reason they decide to go to Mukui Island is because of the psychic Uzuki Yuuko, who was immensely popular in the late nineties. Jun and the others actually once sent a photograph to Yuuko, asking whether that shadow in the background was a ghost, and they got featured in one of her books. The elderly Yuuko passed away after her visit to Mukui Island during a tour along the islands of the Seto Inland Sea, where she and a television crew would seek out paranormal activity. When she arrived on Mukui Island, she sensed an evil spirit on one of the two mountains of the island, and when she visited that mountain in the night, she suddenly collapsed. She died two years later, but she never quite recovered from whatever got to her on Mukui Island. During her lifetime, Yuuko also left several prophecies, and one of them suggest that twenty years after her death, on August the 15th, six people will die on the island where she too fell. 

Intrigued by this story and because of their own link with Yuuko, they travel to the island, arriving late afternoon on the fourteenth. While Haruo had made arrangements before, he's surprised to learn the inn owner suddenly refuses to offer them lodgings, saying the evil spirit will be coming down the mountain soon. They fortunately find another inn, where a few other outsider guests are, some of them also seemingly lured by the prophecy left by Yuuko. That night, they fall asleep, but when they notice Haruo's gone in the early morning, they go looking for him, and find him floating in the harbor. He's obviously dead and the one policeman on the island determines Haruo must have gone out in the night to buy something to drink and fallen into the water. Mainland police is informed, but due to bad weather it might take a while before they can come. One of the other guests, Kazumi, is a nurse, and she points out that despite what the policeman claims, it's clear Haruo was actually murdered before he was thrown into the sea. But as they deal with Haruo's death, they realize the other villagers on the island are being very succesful at avoiding them. Why? Are they involved in Haruo's death? Or are they afraid of the evil spirit which is said to leave the mountains this day? Or has it to do with Yuuko's prophecy six people will die today? Will the prophecy of the six deaths come true on Mukui Island, and is it the work of a human, or something supernatural? Those are the big questions in Sawamura Ichi's Yogen no Shima ("The Island of the Prophecy", 2019).

In a way, the release of this book on its own is pretty creepy. A book about a group of people visiting an isolated location, of which a prophecy has said that on that specific day, people will die? This book was actually released only a month after Imamura Masahiro's Magan no Hako no Satsujin, released in English as Death Within the Evil Eye (disclosure: I translated the book), so it's basically a complete coincidence two mystery novels about prophecies coming true were released within just a month of each other. The funny thing is Sawamura is mainly a horror writer, though this book is touted as him taking on the challenge of writing a proper (horror) mystery story, so it just so happened that on the rare occassion he decides to do focuson mystery, someone else wrote a story with a similar theme. Fortunately, they both do very different things with the theme.

As Sawamura is mainly a horror writer, I had never read anything by him, but I can say Yogen no Shima is a proper mystery novel that is honestly a lot of fun to read. Of course, a lot of mystery stories do rely on horror tropes (or at least, tropes to stir up some tension/excitement), so in a way, it's no wonder Sawamura does a good job at portraying the creepy island of Mukui, without even showing that much of the island/villagers (as the villagers mostly ignore the visitors from outside). The book does a great job at setting atmosphere, especially as it shows you small fragments of local folklore on Mukui Island that seem connected to the villagers' fear of the evil that roams on the mountain, like creepy black idols being placed around houses, supposedly meant to ward off evil. The story also puts the backstory of Yuuko in the interesting context of the boom in popularity in psychics/spirit mediums in the media in the nineties in Japan. We get references to the works of Yokomizo Seishi (the isolated village with its own customs), but also Mitsuda Shinzou and Kyougoku Natsuhiko (local folklore and rituals, and the origins of said folklore) and I was surprised to see this book addressing issues you wouldn't really see in the works of those authors (also has to do with the time period in which this book is set). I really liked some of the points it made regarding this theme, and it worked all really well in the context of this book, both as clues to the main mystery, as well as just painting a surprising background for the prophesized deaths.

As a detective novel, the focus lies not as much on the individual deaths (yes, of course more people than Haruo die), which are committed relatively straightforward, but more on how these deaths tie to a grander mystery, which connects the whole island and the eerie questions about why the villagers are so genuinely afraid of the evil said to lurk in the mountain and the mystery of whether the prophecy will come true or not. A warning here: don't look in the bibliography of this book, because it might tell you more than you want to know in advance, but I do reallly like how Sawamura wrapped up this mystery. I have seen (well, technically listened to) a mystery with a very similar solution before (and with a similar setting and also with ties to folklore...), but the way Sawamura ties this solution convincingly to the unique setting and folklore of Mukui Island, as well as the backstory of the prophecy, and the execution is a lot better than  I had initially expected it to be.

The book sports a marketing slogan stating that the first time you read this book, it's a mystery novel, and the second time it's a horror novel and that honestly really is a great description. While you can read it safely as a straightforward mystery novel, some of the mysteries that are resolved at the end of the book really invite you to read the book a second time, as knowing a certain facts truly changes a lot of the seemingly innocent scenes in the book into something much creepier. Even knowing what is coming.... nay in fact, knowing what is coming really makes this a scary book. In that sense, Yogen no Shima is written and plotted very impressively, being both rewarding as a mystery novel and a horror novel. 

Yogen no Shima is fairly short and could easily have been just a dime a dozen horror novel, but it's a really effective mystery and horror novel, a good example of a piece of simply well executed entertainment media. I believe Sawamura might have written a few more detective stories, so I'll try to find out what the titles are exactly, for this book certainly made me curious to his other mystery output. I don't think this will end up as one of my favorite reads of the whole year, but certain points of this book I will certainly remember for years to come.
