Episode list

Private eyes Randall and Hopkirk are investigating two-timing husband Kenneth Crisby as Marty Hopkirk prepares for his marriage to Jeannie Hurst. Performance artist Gordon Stylus also seeks their help as he believes his wife is suicidal. Marty is killed when a car, apparently driven by Mrs. Stylus, sweeps them both over a cliff. The killer is, in fact, Crisby and Marty's ghost comes to Jeff Randall's aid when Crisby threatens him. However, Marty is destined to remain a ghost with only Jeff being able to see him.

Marty is taught the tricks of the after-life, such as how to levitate objects, by an elderly ghost called Wyvern. Jeannie, meanwhile, who has taken an active role in the agency, is concerned for Jeff when he is overheard talking to Marty. She has him seek psychiatric aid from Dr. Lawyer, but he is a crook who hypnotises his clients into committing crimes for him. When he realises that Jeff is in contact with Marty he erases Marty from Jeff's memory, so Marty impersonates the doctor's voice and advises Jeff on how to thwart the next crime.

Jeannie's young nephew Daniel is troubled by events at his boarding school following the death of a teacher,Mr. Dawkins. Jeff and Jeannie investigate by securing work at the school, respectively as teacher and nurse. The military style headmaster Captain Graves turns out to have a hand in the skulduggery and Jeannie and Jeff are helped by the pupils, as well as Marty, in overcoming him.

Ex-government employee and whistle blower Douglas Milton plans to reveal matters of international security at a forthcoming world conference. He has had a dream in which he foresees his own death and so he hires Jeff and Jeannie as his security. In the event there are several groups out to kill him but they end up killing each other instead. Meanwhile Marty perfects a means of literally raising the wind.

Thirty years previously Marty's father, a policeman, was responsible for the death of a villain called Sidney Crabbe. Now Sidney's ghost has been accidentally re-awakened, and is seeking revenge by going after Marty. In the resultant exchange Jeff is shot and, in his brief time as a ghost, before his revival, he is able to prevent Crabbe from pushing his partner into a flaming pit.

Lauren Dee asks Jeff to locate her husband who went missing in a little village near Preston Storkney called Hadell Wroxted. When Jeff and Marty arrive there they are amazed that everybody can actually see Marty. This is because they are ghosts from a past era and the pair have been led into a trap. Wyvern realises that only Jeannie can save them. . .
