Seven guests are enjoying their stay in a remote country house when the weather takes a turn for the worse and snows them in. ![The Mousetrap](https://londondrum.com/i/eve/the-mousetrap-title.webp) The conversation turns to a murder in London and when Detective Sgt Trotter arrives at the door they discover - to their horror - that the killer is in their midst! As he interviews each person in turn he reveals that they're all hiding a sordid past... but which one is the killer? And who will be their next victim? ## The eight murder suspects ![](https://londondrum.com/i/eve/the-mousetrap-p2.webp) _Mollie Ralston_ has just inherited Monkswell Manor and opened it as a guesthouse. But what is she hiding? _Giles Ralston_ is Molly's husband and is very quick to judge the guests. _Christopher Wren_ is a flamboyant architect with an inappropriate sense of humour, whilst _Mrs Boyle's_ strong-will and uncompromising attitude make her a challenging guest. ![Cast member from The Mousetrap](https://londondrum.com/i/eve/the-mousetrap-p6.webp) _Major Metcalf_ on the other hand, is an affable gentleman who seems all too keen to help his hosts. But why? _Mr Paravicini_ is the complete opposite - a total rogue who acts as if he's visiting from another era. _Miss Casewell_ is about as aloof as you can get, and totally unwilling to discuss anything... and then there's _Detective Sgt Trotter_ himself, the young detective who's come to Monkswell Manor to crack the case. Could it be him? ## The world's longest-running play ![St Martin's Theatre](https://londondrum.com/i/eve/the-mousetrap-st-martins-theatre.webp) _St Martin's Theatre close to Trafalgar Square_ Agatha Christie's classic whodunnit has enjoyed a record-breaking run at St. Martin's Theatre, and has been enthralling audiences for over 28,000 performances across seven decades.
