The murder of Carlos Galecci, a kingpin of organized crime, was not unexpected. Only three days earlier, fearing for his life, he'd hired Los Angeles private eye Johnny Merak to discover who was threatening him. Then he's found seated in his private vault with a knife in his back--a vault whose combination only he knows, a vault no one else has entered in the interim. Summoned to the scene, Merak is hired by Gloria, Galecci’s statuesque blonde wife, to discover her husband's killer, and to determine how an impossible crime has been committed. But in accepting the assignment, Merak soon finds himself marked for death as well! The third entry in this exciting hardboiled crime series.
