It Could be Any One of Us is a typical Ayckbourn play - a cast of six (3 men, 3 women), five of them being of the same family and one outsider.
The father of the family is getting on in years and announces that he has changed his will to include a young lady who he used to teach piano and who he hasn't seen for 20 years. When she arrives on the scene, the arguments that ensue result in a death, but not of who you would expect.
Whodunnit? Well, it could be any one of us!!
