Dial M For Murder Guide

The film’s turning point is the botched murder attempt. In a frantic struggle, Margot kills her assailant with a pair of sewing scissors.

He plants evidence to frame Margot for premeditated murder, turning her act of self-defense into a capital crime. The horror of the second half of the film is the chilling ease with which Tony manipulates the judicial system to finish what his hired assassin could not.

Tony’s motivation is purely mercenary; he doesn’t want Margot back so much as he wants her inheritance. His plan is a marvel of logistical precision: he blackmails a former school acquaintance into committing the murder while Tony establishes a foolproof alibi at a stag party. Dial M for Murder
