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. Episodes 3 to 6 from the cult 1960s series. In 'All Work and No Pay', Jean is convinced that the moving furniture in her flat is her late-husband Marty's (Kenneth Cope) restless spirit, but of course Jeff (Mike Pratt) and the ghostly Marty know better. 'Never Trust a Ghost' sees Marty convinced that a man has been shot dead in his London home after inadvertently witnessing the killing. However, Jeff's attempts to bring the murder to light are thwarted when the dead man turns up... very much alive. In 'That's How Murder Snowballs', Jeff uses Marty to help him form a variety act when he investigates the murder of a mind reader. 'Just for the Record' sees Jeff acting as bodyguard to a beauty contest entrant, but the job is not as simple as it at first seemed.
