Secret Agent, AKA Danger Man

The Mirror's New (1x9)

: 09, 1965

A British diplomat in Paris goes missing for a day, and claims he can't remember it. Investigating, Drake improvises-- first as a German-Irish encyclopaedia salesman (complete with astrakhan cap) and later as the diplomat's gambling buddy. Tortured by two men (one of them Frank Maher, McGoohan's own stunt double), Drake finds the diplomat's triple life has been financed by a dead man.
