In Double, the “Nameless Detective” and Sharon McCone — reunited at a private eye convention in sunny San Diego — team up to tangle with kinky lifestyles, double dealing and multiple murder. When Elaine Picard, head of security at the posh Casa del Rey hotel and an old friend of Sharon’s, falls to her death from a hotel tower, “Nameless” is a distant witness. And when McCone’s zealous pursuit of clues lands her in jail, it’s “Nameless” who posts bail. While Sharon continues to risk her life trying to unravel the mystery of Elaine’s death, “Nameless” puts his own on the line investigating the odd disappearance of a little boy and his mother who’ve vanished from the Casa del Rey without a trace. The two detectives are swiftly drawn into a treacherous maze of past duplicity and present danger. The action races from the Casa del Rey to an ominous menagerie in the hills outside of town, a pornographic curio shop, a political campaign headquarters, a villa on the Mexican seacoast, and an isolated desert mansion with a strange history that belies its even more bizarre current goings on. Double is a crackling and complex thriller from two premier mystery writers
