On this day

November 25, 1952 — Agatha Christie’s The Mousetrap, starring husband and wife Richard Attenborough and Sheila Sim, opened at London’s Ambassador Theatre – and the play is still going.  It is the longest-running production in history, reaching its 25,000th performance in November, 2012. 

The murder mystery has a twist at the end, which audiences have always been asked not to reveal after leaving the theatre. The idea was not to spoil the play for those who had yet to see it. Agatha Christie asked that the short story on which the play is based – Three Blind Mice – should not be published as long as it ran as a play in London. As a result, it has never been published in the UK. 

Another unique facet of the production is that the cast is changed every year, usually in November on the anniversary of the play's opening. There is a tradition that the retiring leading lady and the new leading lady cut a "Mousetrap cake" together. More than 400 actors have appeared in the play since 1952. - onthisday.com

It was, as you have probably already guessed, an(other) uneventful day. The mouse ornament originally belonged to my paternal Grandmother.
