This 1965 series has an excellent theme by Laurie Johnson. Laurie was no newcomer to writing for the screen. In 1959 he had written the theme for the successful British police TV series 'No Hiding Place' and scored 'Tiger Bay', a thriller starring John Mills, his then young daughter Hayley and Horst Buchholz (later to find fleeting fame in 'The Magnificent Seven'). Aside from writing for TV in the sixties he would score 'The First Men in the Moon', Ray Harryhausen and Charles H. Schneer's cinematic working of the H.G. Wells novel, Michael Winner's comedy 'You Must Be Joking', Stanley Kubrick's 'Dr. Strangelove (or How I Learned to Stop Worrying and Love the Bomb)' and 'Hot Millions' featuring a bizarre cast which included Peter Ustinov, Bob Newhart, Dame Maggie Smith, Caesar Romero and Karl Malden. He also composed the themes for the British TV series 'Animal Magic', 'Echo Four-Two', 'Freewheelers', 'Whicker's World' and 'This is Your Life' and most predominantly 'The Avengers', 'Jason King' and 'The Professionals'. The original title of the tune was Latin Quarter, and the original recording can be found on numerous, cheap CD compilations under either of the titles, usually Latin Quarter. They don't write 'em like this anymore!
