Fifteen minutes before the curtain was rung down last night on a Wormwood Scrubs Prison production of the Agatha Christie thriller The Mousetrap, it was discovered that two prisoners were missing,

That was despite the governor receiving a warning from the police that an Escape might be planned.

I like this observation:

Derek Blomfleld - he plays the part of a detective sergeant - thanking the prisoners for their reception. said: "Usually, at the end of each performance, I say ... 'do not tell your friends and relations who done it'." The prisoners applauded loudly.
