COYOTE HILLS

A floater in San Francisco Bay keys up a tough case in this fifth Clay Edison thriller.

Adam Valois, 33, floated ashore a year ago at Coyote Hills, a park on the edge of the Bay. Not a homicide, say the coroner and police, but Adam’s parents are suspicious and hire PI partners Clay Edison and Regina Klein to investigate further. You’re wasting your time, the cops tell Clay, himself an ex-coroner. Officially, Adam wasn’t a homicide victim at all, but a drug user deemed responsible for his own death. But other bodies wash up, and the PIs look for common drug profiles. They even enlist a scientist to write a computer program to analyze the Bay’s complex tidal currents and try to find a common dumping ground for the bodies, if one exists. And it turns out they are homicides after all. There’d been bad blood between the troubled Adam and his successful attorney sister, Kirsten, and she becomes one of several suspects. On a par with the solid plot are some of the character relationships. Regina has a sharp tongue and loves to tease Clay, calling him Poirot. She both admires and challenges him. There’s no obvious sexual chemistry between them; she has another man in her life, and Clay is happily married with two kids who love “Auntie Regina.” Even his brother, Luke, who’d once done time for vehicular homicide, seems to be getting his act together. So Clay lives his life on two levels—other people’s troubles and his own happy family. He and Regina uncover computer messages that cause Regina to exclaim “Sweet baby Moses on a motorbike,” but then Luke visits Clay and teaches his kids how to become pancake ninjas. Like their PI partners, Jonathan Kellerman and his son Jesse make a great team.

Dead bodies and pancakes—who could ask for anything more?
