Blood Type is Stephen Greenleaf's eighth mystery featuring hard-drinking, laconic San Francisco detective John Marshall Tanner, who has been called "the long-sought heir of Sam Spade, Marlowe, and Archer" (San Francisco Chronicle). And Tanner will need all his skills and courage to solve a case the reverberations of which could shake the country.Tom Crandall, war hero, social crusader, and Tanner's barroom confidant, lies dead in an abandoned alley in San Francisco's Tenderloin. The police call it suicide, but Tanner suspects that the affair Crandall's wife was having with millionaire corporate raider Richard Sands may have sealed Tom's fate. And as he investigates, Tanner begins to turn up suspicious clues that lead to the city's vulnerable blood supply, and to Crandall's homeless, paranoid brother, whose accusations are so wild and terrifying that even Tanner is shaken with fear.From the velvet-lined nightclubs of the Bay Area to the burned-out porn shops of the Tenderloin, Blood Type is a novel of greed and malevolence, complete with all the Greenleaf hallmarks: literate writing, satisfying characters, and crackling good dialogue. For fans both new and old, Blood Type is a mystery to chill the veins and quicken the heartbeat. Read Less
