The Final Twist is a radio play by Ken Whitmore and Alfred Bradley, and was Whitmore's last original play for the medium. It was first broadcast on BBC Radio on 30 March 1996. The running time is 90 minutes.
Charlie Nicholson has writer's block, but when he is offered a commission he sees a way to escape his debts. Merlin Foster, an actor, has specific needs: Charlie's script must contain the perfect method and alibi for the murder of Merlin's wife, only then can it be theatrically convincing. Eden, Merlin's young wife, is to remain in the dark so he can surprise her with the play... A murderous and surprising tale.
