Mike Kelly and Doug Kutzli in The MousetrapAgatha Christie's whodunit The Mousetrap is among my favorites in the genre, mostly due to the humor the author wrote into it, as well as the clues she included that make it possible to actually discern who did do it. Although the murderer's identity still comes as something of a shock, the game of figuring out the killer remains fun. I just wish the District Theatre's current production of the piece were as enjoyable.
