Derek Jacobi played Cadfael but was also Claudius in the BBC's serialisation of "I Claudius".

There was no Iain Petherbridge but Ian Carmichael and Edward Petherbridge both played Lord Peter Wimsey.

Douglas Wilmer was quite a good Sherlock Holmes. The Speckled Band gave me nightmares...

Long before playing Miss Marple, Joan Hickson was the wonderfully louche Brighton landlady at the B&B where John Gregson and Dinah Sheridan spent the night in Genevieve.

And John Nettles was solving murders in Jersey for years as Bergerac before he became Barnaby and moved to Midsomer.

Midsomer has had loads more murders than St Mary Meade - Jane Marple had to travel to distant parts to solve murders in Dilmouth etc.

Has Inspector Frost (David Jason)made it to the USA? And does anyone in England know where Denton is?
