Man in a Suitcase (1967)

Arguably the finest series ever put out in the 1960s by Lew Grade's ITC stable, MAN IN A SUITCASE features Richard Bradford as McGill, a discredited ex-CIA agent who is reduced to working for hire as a private investigator. Travelling the world, McGill works as a 'gun for hire', often coming into conflict with his employers due to his strong sense of personal integrity and zero tolerance for shady dealings.
