Randall and Hopkirk (Deceased) (1969)

The Man From Nowhere (1x15)

Air date: Dec 28, 1969

In the bathroom, fresh from her shower, Jean Hopkirk hears a male voice call her name. She finds a strange man lying on the sofa, newspaper in one hand and drink in the other, making himself very much at home. The strange man has an even stranger claim: he is Marty Hopkirk, reincarnated.
