This latest adventure involves the hulk of a steam locomotive that comes to the surface of a lake in Montana in 1950. It contains the bodies of three men who died 44 years before. Flash back to 1906 and a two-year crime spree out west. There's a series of bank robberies by an evil person who murders any witnesses. The government brings in a detective to solve the case, but soon the hunter becomes the hunted. As always, Cussler ties everything together in the end. The author's many fans probably know that at the start, but they will want to read the novel anyway.
