The Devotion of Suspect X

by Keigo Higashino

Published 1 August 2008
Yasuko Hanaoka is a divorced, single mother who thought she had finally escaped her abusive ex-husband Togashi. When he shows up one day to extort money from her, threatening both her and her teenaged daughter Misato, the situation quickly escalates into violence and Togashi ends up dead on her apartment floor. Overhearing the commotion, Yasuko's next door neighbor, middle-aged high school mathematics teacher Ishigami, offers his help, disposing not only of the body but plotting the cover-up step-by-step.

When the body turns up and is identified, Detective Kusanagi draws the case and Yasuko comes under suspicion. Kusanagi is unable to find any obvious holes in Yasuko's manufactured alibi and yet is still sure that there's something wrong. Kusanagi brings in Dr. Manabu Yukawa, a physicist and college friend who frequently consults with the police. Yukawa, known to the police by the nickname Professor Galileo, went to college with Ishigami. After meeting up with him again, Yukawa is convinced that Ishigami had something to do with the murder. What ensues is a high level battle of wits, as Ishigami tries to protect Yasuko by outmaneuvering and outthinking Yukawa, who faces his most clever and determined opponent yet.

by Keigo Higashino

Published 10 April 2012
A man about to leave his marriage is poisoned to death while his wife, the logical suspect, is hundreds of miles away. Tokyo Police Detective Kusanagi and his assistant agree to disagree about the guilty party: was it his wife, his girlfriend, his business associate, or a random crime? They call on physics professor Manubu Yukawa, and even the brilliant mind of "Detective Galileo" is challenged by a crime that is implausible, methodical - and perfect.

Malice

by Keigo Higashino

Published 7 October 2014

Acclaimed bestselling novelist Kunihiko Hidaka is found brutally murdered in his home on the night before he's planning to leave Japan and relocate to Vancouver. His body is found in his office, in a locked room, within his locked house, by his wife and his best friend, both of whom have rock solid alibis. Or so it seems.

Police Detective Kyochiro Kaga recognizes Hidaka's best friend. Years ago when they were both teachers, they were colleagues at the same high school. Kaga went on to join the police force while Osamu Nonoguchi left to become a full-time writer, though with not nearly the success of his friend Hidaka. But Kaga thinks something is a little bit off with Nonoguchi's statement and investigates further, ultimately executing a search warrant on Nonoguchi's apartment. There he finds evidence that shows that the two writers' relationship was very different than the two claimed. Nonoguchi confesses to the murder, but that's only the beginning of the story.

In a brilliantly realized tale of cat and mouse, the detective and the writer battle over the truth of the past and how events that led to the murder really unfolded. Which one of the two writers was ultimately guilty of malice?

A Midsummer's Equation

by Keigo Higashino

Published 23 February 2016

When a man's body is discovered at the base of some cliffs in the small resort town of Hari Cove, the police at first suspect a tragic accident, a misstep that cost the man his life. However, when the victim is found to have been a former policeman and that the cause of death was actually carbon monoxide poisoning, they begin a murder investigation.


Manabu Yukawa, the physicist known as 'Detective Galileo', is in Hari Cove to speak at a conference on a planned underwater mining operation, and finds himself drawn into the case. Did the murder have something to do with the fight of the small community to rebuild itself, or does it have its roots in the town's history?


In a series of twists as complex and surprising as any in Higashino's brilliant, critically acclaimed work, Yukawa uncovers the hidden relationship behind the tragic events that led to this murder.
