Stef Penney's radio adaptation of James M Cain's DOUBLE INDEMNITY was broadcast this month on Radio 4.
An insurance man comes up with the perfect murder, or so he thinks.
Walter Huff has a good steady job in the insurance business and lives a quiet life, until the day he falls for Phyllis, an unhappily married woman, and decides to help her commit murder.
They come up with a plan in which Phyllis's husband will die an unlikely death, by falling from a moving train. The 'accidental' nature of his demise will trigger the 'double indemnity' clause of the policy, forcing the insurance company to pay the widow twice the normal amount.
The couple carry out their plan but things soon turn sour. The Insurance Investigator is suspicious, and so are Phyllis's daughter and her mysterious boyfriend Nino.
