For thirty years the fictional crime novelist and detective Paul Temple, together with his Fleet Street journalist wife Steve, solved case after case in one of BBC Radio's most popular series. They inhabited a sophisticated world of chilled cocktails and fast cars, a world where Sir Graham Forbes, of Scotland Yard, usually needed Paul's help with his latest tricky case. This adventure begins with a body on a train, the word 'Alex' scrawled on the compartment window, and the discovery of a visiting card bearing the name 'Mrs Trevelyan'. More bodies follow, and the two names recur on each occasion. Paul's attempts to unravel the mystery take him to a psychiatrist's consulting room, a rendezvous in London's dockland, a hotel in Canterbury, and many other places before the denouement in a deserted mill and the Temples' elegant flat in London.
