Theatre is the art of storytelling, and the best stories are those that constantly change their shape. In Dennis Kelly's storming new play, Orphans, which wowed critics and audiences when it opened in Edinburgh in August, the narrative morphs and flips like a bad conscience. And for good reason. Long before the final climax, you just know that something isn't right.

Behold the gleaming dark. At one point in this spirited and imaginative revival of Philip Ridley's 1992 play, The Fastest Clock in the Universe, one of the characters says, "We're all as bad as each other. All hungry little cannibals at our own cannibal party. So fuck the milk of human kindness and welcome to the abattoir!" Yes, well. As welcomes go, this is about as pleasant as a razor blade hidden in a cupcake - and perfectly apt for this sharp slice of East End gothic.

Richard Bean's monster mainstage play, England People Very Nice, was about immigration to London's East End - and was easily the most controversial play of 2009. He is a son of Hull (b. 1956). He is one of the most prolific and talented playwrights to emerge on the British new writing scene since the start of the new millennium.
