Deathtrap by Ira Levin

A hugely popular stage and screen success, this ingeniously constructed play offers a rare and skilful blending of two priceless theatrical ingredients - gasp-inducing thrills and spontaneous laughter. Unknown dramatist Clifford Anderson has sent his new thriller to award-winning author Sidney for comment - or has he - Without a success to his credit for some years, Sidney plots with his reluctant wife Myra about how best to plagiarize 'Deathtrap' and when Clifford turns up to discuss the play with the 'Master' events take a sinister turn.
