by Colin Morris.
Four stories concerning the lighter side of C.I.D. work in the North of England.
[Starring] John Barrie

A young suspect is detained for questioning. He refuses to reveal his identity and when interrogated by the C.I.D. replies: 'I've been told that detectives always know everything, so, no matter what I say, you will twist it round the other way to suit your own ends. Therefore, the best thing to say is nothing'.
