PC Dave Litten is on secondment to CID, and is desperate to impress his boss, DI Roy Galloway. Galloway and Litten are about to have a meal at the local pub when a call comes through that a valuable necklace has been stolen from a local aristocrat, Lord Barstow-Smythe. Traffic problems hold them back as they race across Sun Hill trying to get there before the ""woodentops"". With Galloway and DS Roach busy, Litten talks to a local reporter and ends up mentioned in the local paper. Shortly afterwards, he is contacted by a mysterious stranger who offers to locate the burglers if Litten can convince Barstow-Smythe's insurance company to pay him the reward up-front. The Stranger then sets up two young lads to take the fall for the theft, and Litten proudly arrests them. Galloway recognises the MO of the case as that of a notorious conman, and lambasts Litten for his stupidity.
