Whodunnit?

A British format invented by Jeremy Lloyd and Lance Percival, in which celebrities deduce the identity of the murderer in a short play. The panellists interview all witnesses before announcing their chief suspect and the clue which game them away. It's rather like an early version of Cluedo. Shaw Taylor hosted a pilot, and the first series in 1972 was fronted by Edward Woodward – not altogether successfully. But Jon Pertwee became most associated with the show in 1974 after he finished Doctor Who, hosting the next five series up until 1978… after which he starred in Worzel Gummidge.
