Director Val Guest whips up an absorbing and entertaining murder mystery about Brighton policemen who track down the murderer of a woman whose body they find in a lonely beach house. Critic Andrew Spicer points out that the late 1950’s saw a change in the visual style of some noir films made in the U.K. to a bleak and chilling realism, shot in a cold, hard, naturalistic lighting “that corresponded to the brutal violence of the action.” Arthur Grant’s gritty, bleak, pseudo-documentary black and white cinematography sets the tone for the seedy and lonely Brighton location where a brutal murder takes place. This procedural noir is a precursor to the far more direct brutality seen in later British crime films.
