When Yasuko Hanaoka’s ex-husband shows up to exhort money,
she and her daughter kill him. Her neighbor Tetsuya Ishigami, a high school
math teacher, volunteers to help dispose of the body and divert the police’s
attention. What results is a scheme to deceive the police into solving the
wrong crime.
A dead body whose face is smashed to hide the identity shows
up near the river and Detective Kusanagi must identify the murder and find the
perpetrator. On reaching a dead end, he solicits his friend and schoolmate,
physics professor Dr. Manabu Yukawa, to sift through the clues and red herrings.
Thus, pinning the two masterminds against each other.
In The Devotion of Suspect X, Ishigami and Yukawa try to
outwit each other in this cops and robbers game. What Yukawa couldn’t fathom is
the depth in which Ishigami is willing to devote himself to and ultimately
sacrifice for Yasuko. This mystery is among the handful of mystery novels whose
plots surprise me. And though I wish the key characters have more depth, the
plot more than compensates for that flaw and the sparse prose pushes the plot
along without extraneous verbiage. Smart and powerful. I almost wish Ishigami
could triumph over Yukawa.
