On this day in history : 25th November 1952 – Agatha Christie’s murder mystery play ‘The Mousetrap’ opens at the Ambassadors Theatre, London….
With its original cast, including Richard Attenborough and Sheila Sim, it is to become the longest continuously-running play in history…. Agatha Christie herself thought it would only run for about 8 months….
A radio play entitled ‘Three Blind Mice’ was broadcast on the 30th of May 1947 – from this came a short story – on which The Mousetrap was based…. Agatha Christie asked that the story not be published until after the play had finished its West End run…. To this day the story has still not been published in the UK – (although it has been in the United States)….
Agatha was always very particular in trying to ensure her plots were not revealed…. In true tradition at the end of each plot twisting performance of The Mousetrap the audience is asked not to reveal the identity of the murderer outside of the theatre – so as not to spoil it for future audiences….
