When Amos Walker grants the last wish of a Detroit madam, he finds himself enmeshed in the mystery of the murders-53 years apart--of a father and son . . . with the same gun, in a place where it should be impossible for a gun to be! Before he can track down the murderer he's accused of the son's murderer, fingered by the mob, and on the spot with the FBI. A wonderfully suspenseful, exciting noir detective thriller by one of the masters of the genre.
