The Baron, John Mannering, was an international crime fighter in the world of fine art and antiques. A Texan living in London, he drove a light brown Jensen CV8 - registered BAR 1 - which featured extensively in the opening credits and in many of the 30 50-minute colour episodes that were screened in 1966 and '67. The car was particularly swish in featuring a radio telephone. Star of the show was the red-haired American actor Steve Forrest (who, in the '70s, turned up in the American series 'SWAT') with Sue Lloyd as his sidekick, fresh from 'The Ipcress File' and yet to feature in 'Crossroads'. She occasionally drove an MG 1100 or a Daf.
