Agatha Christie’s Mousetrap is the longest running play in history for a reason. The famous story, which has been running since it premiered in 1952, is masterfully saturated with suspense. It’s a classic murder mystery that takes place at a remote guesthouse in England, in which an amateur detective somehow exposes the not-so-charming underbelly of a seemingly pleasant community. Shotgun Players’ Artistic Director Patrick Dooley has been a Christie fan since he discovered her work on his grandmother’s dusty bookshelf as a kid. He chose Mousetrap as the culmination to Shotgun’s first season of all female-written plays. It premiered in early December, but, unsurprisingly, it was extended until January 24. That means if you haven’t seen it already, you still have four more nights to find out whodunit.
