Famously the world’s longest consistently running play – pandemic excepted – Agatha Christie’s Mousetrap has now been running for 70 years, and is one of those plays that everyone is presumed to see once in their lives.

The murder-mystery storyline is set in “the present”, which presumably means England as it was around the time when the play came out in 1952, including the postwar continuation of World War II rationing.

The play is based on a short story but Christie asked that the story not be published as long as it ran as a play in the West End of London, and it still hasn’t been published within the UK (although you can buy it overseas if desperate). Its long-running popularity is in part thanks to the fact that once you attend, you’re not supposed to tell anyone whodunit, keeping the secret safe for the next generation of theatregoers.

So if you haven’t seen it, at the moment, there’s an offer on Mon-Thur performances between 1st May to 13th July — if booked by 11th May from here.

The offer gets you seats that normally sell for £36 for just £23 – which means they’re actually cheaper and better than the very back row of seats that are usually the cheapest.

There are also offers on £71.40 seats for £45 and £94.80 seats for £69.50.
