The Aosawa Murders

The novel starts in the 1960s when 17 people die of cyanide poisoning at a party given by the owners of a prominent clinic in a town on the coast of the Sea of Japan. The only surviving links to what might have happened are a cryptic verse that could be the killer's, and the physician's bewitching blind daughter, Hisako, the only person spared injury. The youth who emerges as the prime suspect commits suicide that October, effectively sealing his guilt while consigning his motives to mystery.

The police are convinced Hisako had a role in the crime, as are many in the town, including the author of a bestselling book about the murders written a decade after the incident, who was herself a childhood friend of Hisako’ and witness to the discovery of the killings. The truth is revealed through a skilful juggling of testimony by different voices: family members, witnesses and neighbours, police investigators and of course the mesmerizing Hisako herself.

The Aosawa Murders takes the classic elements of the mystery genre but steers away from putting them together in the usual way, instead providing a multi-voiced insight into the psychology of contemporary Japan, with its rituals, pervasive envy and ever so polite hypocrisy. But it’s also about the nature of evil and the resonance and unreliability of memory.
