The Mousetrap opening in 1952 began the theatrical run of Agatha Christie’s most famous play, which was still running at St Martin’s Theatre in the West End when the account was written and was described as the longest-running play in history.

Opening and theatrical legacy

The play opened in 1952, placing its first performance within the later phase of Christie’s long career as a dramatist. Its continued run at St Martin’s Theatre in the West End turned that opening into the start of an exceptional theatrical duration: the account identifies it as the longest-running play in history.

Place in Christie’s career

The opening extended Christie’s success beyond novels and short stories into the theatre. Her earlier stage milestone had been the West End success of Alibi, the 1926 dramatization of The Murder of Roger Ackroyd. The later opening of The Mousetrap was distinct in both its prominence and longevity: it became her most famous play and remained in performance for decades.
