Are you allowed to call yourself a theatre fan if you haven't seen The Mousetrap, the West End's longest-running play? Possibly. But I've ticked that box now.
So what was it like? Well, it's a fun, frothy West End play that is in part carried by its status of being long-running and a West End institution.
It's an Agatha Christie, which means everyone acts in a way that puts them under suspicion.
And I don't know if you are like me, but thoughts about characters always cross my mind early on, which I then put to one side but inevitable prove true.
Of course, I never verbalise my suspicions in the interval, so can't prove that I was kinda on the right track. But I was, so there. Not that I guessed everything because I didn't.
There are some nice little twists, as you'd expect from Christie.
