"MOTAS: Mystery of Time and Space"
Huh, apparently there are a handful of mystery novels in Japan about Escher...
After the Meiji Restoration in 1868, Japan opened up its ports for trade after centuries of closure, but that didn't mean foreign traders were free to go anywhere they wanted. Foreign settlements were opened at select places across Japan, most notably in Yokohama and Kobe. The foreign settlement in Osaka was located in Kawaguchi, and it also provided the home for a certain Dutch civil engineer called George Arnold Esher (who has a son called M.C. Esher...), who was hired by the Japanese government as an advisor, overseeing hydraulic projects like the restoration of the Yodo river in Osaka. One night Escher returns to Osaka after overseeing the harbor in Mikuni, when he is kidnapped and stuffed in a hansom coach. The threats by his assailants make it clear they're actually not after him, but a tradesman called Hans Boemler, but attempts at clearing up the misunderstanding fail. The blinded hansom doesn't allow Escher to see much, but he notices that his kidnappers brought him to the Kawaguchi Foreign Settlement (which is where he was heading anyway), and he's brought into a room, where he finds... the body of Boemler, who apparently had already been found and killed by his kidnappers' boss. With a body on their hand, and a mistaken abductee, the fiends decide to burn the place down, but Escher is miraculously saved from the fire. But in the subsequent investigation, one problem arises: Boemler's body was never found. Escher and his comrades try to figure out what happened exactly that night, but none of their theories work, and Escher would eventually leave Japan.
Morie Shunsaku takes up the case of Mr. Shioji in 2001, who is accused of murdering Udou, a businessman who together with a few other men beat Shioji up at the golf course, after Shioji assaulted them first. Shioji used to be a police officer, but he was basically crippled by Udou and his friends back when they were students and participating in the student riots in the 70s, giving Shioji enough of a motive for murder. Udou had been strangled on the street at night, and with witnesses stating they saw Shioji tailing Udou, and even someone who saw the murder happen from across the street, Shioji's guilt seems clear, but he swears that he never touched the man and that Udou was assaulted by some invisible ghost, as he saw Udou suddenly struggling and falling down on the street even though there was nobody around. This alone sounds like an impossible crime, but Morie also learns that in 1970, Udou's circle of friends was involved with a mysterious murder. The friends had been drinking near the warehouse district, when Hikura headed back home. He made his way through Ajigawa Tunnel (a deep, long tunnel running beneath the Aji River) and at the other end of the tunnel, he discovered the body of Toomi, one of the friends he had been drinking with. While Hikura had not seen Toomi when he left (meaning Toomi could've come here before him), Hikura did see Udou and the others before he left and none of them could've overtaken him to arrive at the tunnel earlier and commit the murder, as there is only one single road to the tunnel. Morie has a nagging feeling that the Ajigawa Tunnel Murder has some similarities with the George Esher case he read about in a pamphlet, and he decides to try to solve these cases too in Ashibe Taku's Toki no Misshitsu ("A Locked Space in Time", 2001).
Toki no Misshitsu is the tenth entry in this series starring the defense attorney Morie Shunsaku, who more often than not ends up amateur sleuthing. And as you can gather from my feeble attempt at a summary, it's also a very ambitious work, that tries to do a lot. I do have to say that the title can be a bit misleading, as while they talk about sealed spaces and locked rooms all the time, most of the situations aren't really locked room mysteries. The 1876 Escher case for example is called a sealed space because the Kawaguchi Foreign Settlement is a "sealed space" (extraterrorial ground) from which Boemler's body disappeared. The Ajigawa Tunnel murder is considered a "locked room murder" because the suspects were all located at one side of the tunnel and none of them could've made it to the other side of the tunnel without being seen by the reliable witness (i.e. the area between the witness and the victim was "a locked space" for the suspects, but the murder was possible for anyone on the other side of the tunnel). There is another problem presented in the prologue, where Morie is riding on the Aqua-Liner aqua-bus with a certain package, but he can't figure out how his opponent is going to retrieve that package and escape from the police, as the canals and rivers of Osaka basically make any quick escape impossible. The only real impossible crime situation is that of the Udou murder, where the defendant says Udou was attacked by a ghost, and a witness says he saw the defendant assault the victim, but even then it's not really a locked room mystery. So the title is rather misleading.
To be honest, the four "sealed space" mysteries are not likely to make much of an impression if taken alone. The solutions for both the Aqualiner mystery and the Udou murder are fairly simple to guess and I wouldn't be surprised if you had seen similar answers elsewhere. The Escher and the Ajigawa Tunnel cases are more interesting, as their underlying trick is the same if the execution is different, and Morie manages to solve the Ajigawa Tunnel case only because he figured out the Escher case. It has to be noted that once again, their base idea is nothing particularly inspiring, but at least the synergy is here between these cases, and it is interesting to see how two completely different situations, set in very different times, are ultimately built around the same notion, and the way it ties back to M.C. Escher (who makes an appearance as a kid) is pretty neat. I actually thought this novel to be packed way too full (besides the four "sealed space" mysteries, there's even a code cracking section, and more), and personally, I think a novel only focused on the Esher and Ajigawa Tunnel cases would've worked better, as the other elements in Toki no Misshitsu feel far less integrated compared to these two parts. There is not that much synergy between the various parts, so at times the novel does feel like a collection of various mysterious events, rather than one cohesive story (especially as there's just so much going on in this novel across various time periods).
I've mentioned in earlier reviews of Ashibe's work that he loves weaving historical and literary research into his stories: the pastiche stories with famous fictional detectives in his The Exhibition of Great Detectives series (Part 1 and Part 2) are excellent examples of how Ashibe not only shows great understanding of the works he imitates, from writing style to publication history, but you also see how he does a tremendous amount of research in world history, as he also makes connections between his fictional tales, and real world events. His work is always brimming with historical references and explanations, which can also backfire a bit: I thought Satsujin Kigeki no Modern City was going a bit overboard with its explanations of basically everything in 1930s Osaka. With a story set in the three distinct time periods (1876, 1970 and 2001), you're sure to find plenty of references and historical explanations in Toki no Misshitsu too, though I didn't find it as intrusive as with Satsujin Kigeki no Modern City. You are sure to learn a lot while reading this book, but the way Ashibe uses the historical A.G. Esher for his mystery for example is pretty neat and a good example of how to do a historical mystery. It's also clear that Ashibe loves the city of Osaka, and as always, you're always seeing a lot of the Water Capital in various forms. The amount of research in the city's history can sometimes a bit overwhelming and distract a bit from the main mystery plot, but readers into atmosphere will definitely love Toki no Misshitsu, and Ashibe's in general, I think.
I might not be the ideal reader of Toki no Misshitsu, as I freely admit I'm a reader who focuses more on the core mystery plot and less on "story". Personally, I think a tale focusing solely on the two most interesting situations, the Escher and Ajigawa Tunnel cases, would've worked better than the way it is now, with a lot going on. The idea of using Escher and the Kawaguchi Foreign Settlement is quite original though and the idea of a "sealed space" mystery with the tunnel is also interesting, even if the "locked room" moniker is a bit misleading. I do think that people who really like to read "an epic story" will like Toki no Misshitsu as Ashibe really went all-out here, with so much mysteries to be solved in the city of Osaka, spanning a period of more than a century.
