Dial M for Murder has been remade four different times for television, but is perhaps best known as the classic film directed by Alfred Hitchcock starring Ray Milland and Grace Kelly. It remains one of the most suspenseful thrillers ever written, centering on Tony Wendice, an ex-tennis pro, who plots to murder his wife, Margot, because she had an affair, now over, but more importantly to get her money. To accomplish that goal, he blackmails an old school acquaintance to strangle her. When things go drastically wrong, Tony sees another way to guarantee her death and his wealth. Will he succeed or will his plot to murder Margot be foiled?
