SILENT PARADE

Physics professor Manabu Yukawa’s fourth round of criminal investigation leads from a discovery of corpses old and new to a series of mind-boggling theories about their connection.

Three years after gifted singer Saori Namiki disappeared from the Tokyo suburb of Kikuno, her parents, Yutaro and Machiko Namiki, must face the news that her body has been found. The circumstances of the discovery are even more disquieting: Saori’s corpse has turned up in the charred skeleton of the house of Yoshie Hasunuma, along with that of the homeowner. Director Mamiya, the head of the Tokyo Metropolitan Police Department’s Homicide Division, instantly senses that he’s in deeper waters because Yoshie’s son, Kanichi Hasunuma, was the leading suspect in the murder of Yuna Motohashi, a schoolgirl whose dismembered remains were discovered in the nearby mountains 23 years ago. Shortly after Hasunuma, who maintains a surly silence when the police question him, puts in an appearance at Namiki-ya, the restaurant the Namikis own, to blame them for the way the police have been pressing him and demand recompense for his inconvenience, he’s smothered to death during the town’s annual civic parade, and most readers will breathe a sigh of relief. Not Chief Inspector Kusanagi’s old friend Detective Galileo, as Yukawa is nicknamed. In a rousing triumph of the scientific method, the supersleuth, insisting, “I’m just a regular physicist,” spins out a series of increasingly intricate hypotheses about this latest murder, tweaking each one when he’s confronted with contrary evidence, then generating newly refined and revised theories that are even more impressive in their ability to cover the sprawling network of new data.

Fans of golden age puzzles will wish this one could go on forever.
