From the Collins Crime Club archive, the forgotten second novel by Freeman Wills Crofts, once dubbed 'The King of Detective Story Writers'. When the body of Sir William Ponson is found in the Cranshaw River near his home of Luce Manor, it is assumed to be an accident - until the evidence points to murder. Inspector Tanner of Scotland Yard discovers that those who would benefit most from Sir William's death seem to have unbreakable alibis, and a mysterious fifth man whose footprints were found at the crime scene is nowhere to be found… This Detective Story Club classic is introduced by Dolores Gordon-Smith, author of the Jack Haldean Golden Age mysteries.
