When the consignment turns out to be an attractive blond, Jeff concedes that the assignment is to his liking, until doing so takes on murderous implications. 20. Money to Burn Hot money proves a big temptation Randall but it always puts him in a hot spot. He finds himself accused of stealing £500 intended for incineration, and where there smoke there's fire, this time in the shape of a sultry cabaret singer. 21. The Ghost Talks With Jeff confined to a hospital bed, Marty seizes the opportunity to tell his captive partner about a spy drama he handled while he was still alive involving MI-5 and a spy ring, the details of which he had never revealed before. 22. It's supposed to be Thicker Than Water Playing postman to deliver an envelope to an escaped convict strikes Jeff as a simple affair - until he discovers that the envelope contains an invitation to murder and before long, Jeff's own life is on the line.
