American actor Richard Bradford played McGill (we never knew his first name) in this 1967 series about a wrongly discredited CIA man turned bounty-hunter willing to take on any job that paid him $500 a day plus expenses. His work took him around Britain and Europe, and even as far as Africa, with a battered leather suitcase as his only friend. The hunched Bradford was only 30 at the time, but his grey quiff made him look much older. He was an incongruous figure in the light green Hillman Imp that was his regular transport, although he sometimes used a Mk 3 Zephyr. With an eternal roll-up in the side of his mouth, he got beaten up most weeks and was never able to form relationships with his female co-stars because the script demanded that he moved on in the quest to clear his name. Latterly Bradford popped up as Cagney's father in 'Cagney and Lacey' and, these days, seems to specialise in fat, corrupt Irish-American cops.
