It's good to have a ghost on your side in the private eye business, especially in cases when an invisible ally can really turn the tide in your favour. Mike Pratt plays Jeff Randall and Kenneth Cope is his ghostly partner Marty Hopkirk, cursed to wander earth for 100 years.
7. Murder Ain't What It Used To Be? Marty has a ghostly rival, Bugsy, a gangster who met his demise in the Roaring Twenties. Not only does he have a repertoire of better tricks, he is also out to kill one of Jeff's clients. 8. Whoever Heard of a Ghost Dying? A criminal mastermind and his clairvoyant, co-conspirator, discover the reason for Randall's recent success at detection - the late Marty Hopkirk. They plot to make the duo fall guys for robberies and even try to exorcise poor Marty! 9. The House On Haunted Hill It's a case for Marty when Jeff is asked to investigate the mystery of a "haunted house". It's just as well as Jeff is preoccupied with solving a diamond robbery. 10. When Did You Start to Stop Seeing Things? The day Randall and Hopkirk have been dreading has arrived. Jeff can no longer see or hear his ghostly partner. To Marty's consternation Jeff doesn't even appeared to be bothered by this!
