Young lawyer Nicholas Turner was plagued by financial issues, and when his wife witnessed the incident from the front window, he fell off the roof. When Barnaby and Scott investigated the possibility of a foul, Turner's neighbor and friend Jack Wilmot mysteriously disappeared. Wilmot's two eccentric friends, an infatuated wine snob and an unsuccessful game show host, were questioned when Barnaby began exposing the details of a carefully planned scam involving four men. Not long after, DCI Barnaby had two bizarre murder cases in his hands, caused by a pile of broken empty wine bottles.
