A Closed Book, essentially a two-hander for two superb actors, is in the tradition of Death Trap or Sleuth offering twists and chills in a scenario of mounting terror.
A Closed Book is a chilling psychological thriller in which Sir Paul, a distinguished author, blinded in a horrific accident, advertises for an amanuensis, an assistant to help him with his writing. He employs the amiable Jane Ryder to be his eyes as he revisits scenes from his past and works on what he intends to be his final opus.
Jane appears to be ideal: attractive, intelligent, and unruffled by her employer’s abrupt eccentricities. But gradually we come aware that Jane has another agenda. Incrementally, Sir Paul’s familiar surroundings are altered. His housekeeper is diverted away. Strange things happen around the house and he becomes increasingly dependent on his new assistant.
Jane plays increasingly sadistic games until their relationship breaks down and it becomes clear that Jane intends to kill Sir Paul. Paul grasps this too late to save himself, but the plot carries further savage twists before it reaches its conclusion.
