Ian Carmichael is Lord Peter Wimsey, with Patricia Routledge as his mother, in this BBC radio full-cast dramatization. Wimsey's mother has heard through a friend that Mr. Thipps, a respectable Battersea architect, found a dead man in his bath, wearing nothing but a gold pince-nez. Lord Wimsey makes his way straight over to Mr. Thipps, and a good look at the body raises a number of interesting questions. Why would such an apparantly well-groomed man have filthy black toenails, flea bites and the scent of carbolic soap lingering on his corpse? Then comes the disappearance of oil millionaire Sir Reuben Levy, last seen on the Battersea Park Road. With his beard shaved he would look very similar to the man found in the bath--but is Sir Levy really dead?
