Agatha Christie Poirot - taken at the flood

A man returns from the dead, and the body of a mysterious stranger is found in his room.

A few weeks after marrying an attractive young widow, Gordon Cloade is tragically killed by a bomb blast in the London blitz.

Overnight, the former Mrs Underhay finds herself in sole possession of the Cloade family fortune.

Shortly afterwards, Hercule Poirot receives a visit from the dead man's sister-in-law who claims she has been warned by `spirits' that Mrs Underhay's first husband is still alive.

Poirot has his suspicions when he is asked to find a missing person guided only by the spirit world.

Yet what mystifies Poirot most is the woman's true motive for approaching him.
