The corpse in private eye Kinsey Millhone’s third adventure (“A” Is for Alibi and “B” Is for Burglar is that of Bobby Callahan, a young man she first meets while both are working out in a local gym. Bobby is convinced the car crash he’d been injured in was really an attempt on his life and, fearful of another assault, persuades Kinsey to investigate. A few days later, Bobby is indeed killed, and Kinsey stays on the case. She is befriended by Bobby’s wealthy mother, his opportunistic stepfather and druggie, anoretic stepsister. She learns Bobby was having an affair with a friend of his mother’s whose first husband had been killed in a suspicious burglary, and whose second is county pathologist. While the almost hard-boiled Kinsey ferrets out the ugly secrets behind Bobby’s death, she’s also trying to save her elderly landlord from the schemes of the scam-operating senior lady he’s smitten with. Kinsey Millhone is nobody’s fool; she’s also sensitive, funny and very likable. Writing with a light, sure touch, Grafton has produced a fast-moving California story about quirky, believable people.
