Secret Agent, AKA Danger Man

Don't Nail Him Yet (1x19)

: 22, 1964

British intelligence suspects that Rawson is selling secrets. Drake poses as a wimpy schoolteacher picked on by teenagers, wins Rawson's friendship, and trails him even to a soccer game, but resists simply pulling Rawson in until he can prove the treason. Following the man to a bookstore, Drake sees his quarry bolt, but discovers a lovely accomplice (Sheila Allen) and a sinister spymaster.
