See Agatha Christie's plots and twists of a classic murder mystery with The Mousetrap at St Martin's Theatre in London's West End.


Head to St Martin's Theatre to see the longest-running play in the world, Agatha Christie's The Mousetrap.

One of the West End's most popular shows, the first performance of The Mousetrap was in London in 1952. 

What is The Mousetrap about?

The Mousetrap is a classic whodunnit that takes place in a remote English country house hotel during a snowstorm. The hotel owners and their guests are shocked when Detective Sergeant Trotter turns up and tells them that a murderer is coming to the hotel. But it seems the murderer has already arrived when one of the guests is found dead!

The cast looks down to perhaps what might be the mysterious murderer.

The Mousetrap is written by Agatha Christie, the queen of the crime novel and creator of some of the greatest detectives in fiction. Expect the usual twists, turns and double-bluffs as the audience tries to work out which character is responsible for the murder.

After the show, you'll be asked to keep the identity of the killer a secret so the play remains a mystery to others. After more than 70 years on the London West-End, this classical Whodunnit still keeps the public on the edge of their seats.
