Randall & Hopkirk (Deceased) S01E15 - The Man From Nowhere

Jeannie is approached by a man who claims to be the reincarnation of Marty. He is very convincing and she is eventually taken in - unlike the real Marty. The impostor takes her to a hotel in the Cotswolds where the Hopkirks spent their honeymoon - shadowed by Marty and Jeff - and two other men. It transpires that the trio are robbers who buried their loot in the vicinity but had a car smash involving the Hopkirks. The false Marty lost his memory in the prang and is hoping that Jeannie can lead him to the spoils. Fortunately the real Marty - and Jeff - intervene, with Jeff claiming the reward.
