The lack of a satisfying solution to the whodunit at the heart of Tallman's fourth historical set in 19th-century San Francisco (after 2007's The Cliff House Strangler
) is the only real flaw in an otherwise solid read. Idealistic and iconoclastic attorney Sarah Woolson investigates the bludgeoning murder of botanist Nigel Logan, who was at a party with Woolson's judge father only the night before and whose body was found near the Woolson home. Several days later, a friend of Logan's, a church deacon, apparently falls victim to the same killer. When the police latch onto some Chinese immigrants as the culprits, despite the absence of any real evidence, Woolson bravely takes on their defense. Convincing period detail supports an engaging lead who's a more plausible character than, say, Rhys Bowen's Molly Murphy, a PI in early 20th-century New York City. The romantic subplots don't overwhelm the mystery, but the ending will surprise few. (Mar.)
