One Saturday night, a masked gunman walks into a jazz club and murders the drummer with a sawn-off shotgun. Shortly afterwards, Detective Chief Inspector Brock and Detective Sergeant Poole find themselves taking an interest in the guests at a party in Surrey's stockbroker belt - a party where naked girls were thrown into the swimming pool by the villains who were with them.

This leads them back to a five-year-old robbery and a series of interviews with a number of armed robbers. Then numerous extra-marital affairs come to light and a bullion van is attacked . . .
