Think tall, loose limbed, assured and astute Texan, think Saint and you have John Mannering, cattle rancher, international antique dealer who is regularly called in by the secret service to trouble shoot dangerous problems throughout the world (well Elstree Studio actually with bought in stock footage).
Co-starred is Sue Lloyd as Cordelia Winfield, a long legged English rose, quite different to the girls in similar programs, complementing the Baron's character very well and frequently having to be rescued at the last moment by him.
Equal third star is the car, the incomparable 1966 Jensen Chrysler V8 powered "Interceptor" that precisely matched Mannering's personality and is a joy to watch whenever it appears.
The stories are the usual entertainment style thrillers of the late sixties, but there is not a single weak story.
After thirty episodes I wanted more, strongly recommended for lovers of the genre.
