It is a murder mystery play by Agatha Christie, which had been playing in the West End theater since 1952. The play ran continuously until 16th of March, 2020 as the stage performances were discontinued due to the COVID-19 pandemic. It is the longest running West End theater show with its 27,500th performance taking place on 18th of September, 2018. Officially Incredible!!
To Break The Record, A play must have a longer initial run in a professional theater than that of The Mousetrap
