the devotion of suspect X
I read this book (I bought along with the House of Silk in Oxford) over a wee more than a day: it reads fast and it reads well! Really really well. The devotion of suspect X is a Japanese detective story where the reader knows the true murder story from the start and waits for the police to uncover the culprits, except there is a twist in the story. And another twist in the twist. And yet another one…
“That guy might be a genius mathematician, but he’s certainly a novice murderer.”
“They are the same thing,” Yokawa stated simply. “Murder probably comes even easier to him.”
The main characters are three graduates from the Imperial University in Tokyo: one in sociology (who acknowledged only visiting the library twice), one in physics who is still working as a researcher there and one in mathematics, who left the academic system to teach bored high school students—while still working on his free time on the Riemann conjecture. The X in the title is actually related with the mathematician, who handle the murder as a maths equation and the murderer as an unknown X.
“For instance, I give them a question that looks like a geometry problem, but is in fact an algebra problem.”
The book starts somehow sedately but, as the personalities of the mathematician and the physician unfold, it gets more and more gripping, to the point I could not let go (and was glad of my battery giving up during the flight to Montpellier so that I could keep reading!). I also appreciated very much the depiction of the Japanese society in the novel and found myself visualising the characters in some parts of Kyoto I visited last year (although the story takes place in Tokyo). The harsh condition of single women in this society is also well-exposed and central to the story.
“He had calculated that it would take him roughly another twenty years to complete his work on this particular theory. Possibly even longer. It was the kind of insurmountable problem worthy of an entire lifetime’s devotion. And of all the mathematicians in the world, he was in the best position to crack it.”
There are a few imperfections, of course, like the final scene which is both “necessary” and clumsy. Or the uncovering of the (brilliant) last twist by the physicist. But the plot holds solidly as a whole and makes me want tore-read the book again, to reanalyse every situation with the knowledge of the “full” truth. (I also disliked the connection with Stieg Larsson made on the front cover: it differs very very much from Millenium in that the central female character Yasuko remains a victim throughout the book without ever taking over. There is no political perspective to be found in The devotion of suspect X.) The book was adopted into a movie, I wonder how well it translates…
