A fascinating meditation on human cloning, personal identity and the conflicting claims of nature and nurture. Bernard thought he was an only child. One day he learns the shocking truth: he is just one of a number of clones. Together, he and his father confront epic questions of identity, intimacy and belonging. Caryl Churchill's play A Number pushes the boundaries of science and ethics with an astonishing twist on the dynamics of the father/son relationship. It was originally produced at the Royal Court Theatre, London, in 2002, winning the Evening Standard Award for Best Play.
