Double indemnity and

Double indemnity: When smalltime insurance salesman Walter Huff meets seductive Phyllis Nirdlinger, the wife of one of his wealthy clients, it takes him only minutes to determine that she wants to get rid of her husband--and not much longer to decide to help her do it. Walter knows that accident insurance pays double indemnity on railroad mishaps, so he and Phyllis plot frantically to get Nirdlinger on--and off--a train without arousing the suspicions of the police, the insurance company, Nirdlinger's dishy daughter, her mysterious boyfriend, or Nirdlinger himself. This brief but complex novel is a perfect example of the ordinary-guy-gone-disastrously-wrong story that Cain always pulls off brilliantly.
