George Frobisher in Campion: Case of the Late Pig
Mild mannered Judge George Frobisher (Moray Watson) has a leading role as Sir Leo in this Campion murder mystery. George plays the classic country gent who wants assistance in finding out who murdered an unwelcome guest at his club.
Wikipedia has a current photo up of Moray Watson. He's 81 and looks healthy and well.
I also recently spotted Judge George while watching the first episode of Murder Most English (1977).
