Doctor Who star Jon Pertwee is your host in this highly popular, light-hearted panel game where viewers are invited to play detective – pitting their wits against a panel of celebrities to solve a fictitious murder mystery. The shows brilliantly original formula, devised by comedians Lance Percival and Jeremy Lloyd, presented short dramas laden with clues and red herrings to be pieced together by the celebrity panellists, who would then question the characters involved and finally point the finger at the most likely suspect.

Lively repartee was the order of the day and joining Pertwee in this series is a veritable who is who of 1970s television: Richard OSullivan, Patrick Mower, Aimi Macdonald, Anthony Valentine, Harry H. Corbett, Arthur Mullard and Rodney Bewes join up with celebrities Jackie Collins, Henry Cooper and Kingsley Amis to track down whodunnit.
