The body of tramp Billy Blake is discovered in the garage of Amanda Powell, at her luxury Docklands flat. Investigative journalist Mike Deacon learns that Amanda's husband disappeared some time ago, suspected of a £10 million fraud.
Deacon discovers Billy Blake's real name was Peter Fenton, a diplomat who's wife killed herself but he has no connection to Amanda. When DeVriess is also found murdered in her garage, Deacon believes she is only guilty of hiding the truth.
