Agatha Christie’s The Mousetrap – the longest running show in the world, which has been suspended since the pandemic resulted in the closure of UK theatres in March 2020 – is to re-open in the West End on Monday 17 May 2021.

Two sets of casts – comprising Olivier Award winners and highly acclaimed stars of TV and film – will come together for the iconic thriller as it re-opens at the St. Martin’s Theatre on the day that Stage 3 in the Government’s “Road Map” to ease restrictions across society comes in to effect.

The Mousetrap will celebrate 70 years in London in 2022. It has been performed 28,200 times in London and sold over 10 million tickets. To celebrate the 50th anniversary in 2002, The Queen and Duke of Edinburgh attended a special Gala performance

main preview

News on the radio reveals that a woman has been murdered, and a note is found attached to her body. This intricate story is set at a nearby guesthouse, where the residents become snowed in with no means of contacting anyone from the outside world. The cast of eight include the newly-married couple who own Monkswell Manor, a group of guests, and a detective who stays at the estate to question the residents. As the guests become more suspicious of each other, it becomes clear that no one is quite what they seem. Will the murderer be revealed before they target their next victim?

After making its premiere in Nottingham in 1952, “The Mousetrap” opened in London, breaking numerous records and continuing to be the world’s longest running play. Now celebrating over 65 years in the West End, Agatha Christie’s classic whodunit story is a mixture of 1950s drawing-room comedy and murder mystery.

What to watch for

Look out for the wooden sign at the entrance to the theatre — it tallies up the number of performances to date and will let you know which performance of this record-breaking show you are attending.

The shows was written as a gift for Queen Mary’s 80th birthday in 1947.

Cassidy Janson and Danny Mac will star in The Mousetrap's return from 17 May 2021.

The clock above the fireplace in the main hall is the same clock that was used on opening night in 1952.

Former cast members have given record-breaking contributions. One of the original cast members (David Guyler) provided the prerecorded voice of the newsreader in the shop, while David Raven is in the Guiness Book of Records as the “Most Durable Actor,” having performed 4,575 performances as Major Metcalf. The late Nancy Seabrooke also holds a record for an impressive 15 years as an understudy.

Agatha Christie gave her grandson, Mathew Pritchard, the rights to the play for his ninth birthday.
