Murder mysteries keep getting more and more complicated. The killer is never who you would initially assume, nor is it the second suspect that comes to mind. It’s rarely the third person, either, and the motive isn’t simple revenge anymore—it’s always something much more involved than that.

In that vein, Aaaaaagh! Murder! is very involved. The plot twists and turns relentlessly, and each of the four main characters is similarly suspect at one point or another. But much like Clue, the film adaptation of the popular board game, Aaaaaagh! Murder! makes something of a mockery of the murder mystery genre, being both so over-the-top and so cloyingly discrete as to make it impossible to find out who’s responsible for killing the house staff at Gloomethorne Manor (whose owners are Lord and Lady Killington, natch) until the final minutes of the hour-long performance.

While some of the dialogue tries too hard to be funny and a few of the characters are too effusive for their own good, the play remains engaging because it never takes itself too seriously. That becomes most obvious when the killer is exposed to the audience—their motive is so complicated and convoluted that even the characters wonder out loud why someone would go through so much trouble to commit a crime.
