Danger Signal
Directed by Robert FloreyHilda Fenchurch is a Los Angeles secretary living with her mother and younger sister Anne in a modest but respectable household. When the smooth-talking Ronnie Mason insinuates himself into their lives, Hilda is quickly drawn to him – unaware that Mason is a practiced manipulator who has left a trail of dead women behind him. He is, in the most precise sense, a man who solves his problems by eliminating them.
Mason's scheme is to court Hilda for her small savings, but the plan grows complicated when Anne, younger and more openly trusting, also develops feelings for him. Dr. Jane Silla, a psychologist who has encountered Mason before, begins to piece together his pattern, while Hilda's colleague Thomas Turner and the straightforward Dr. Andrew Lang represent the kind of honest affection Mason has no use for. As Mason's intentions sharpen, the Fenchurch household becomes a closed arena in which charm and danger are indistinguishable.
Danger Signal belongs to the cycle of postwar domestic noir in which the threat arrives not from the underworld but from the parlor – a well-dressed predator operating inside the codes of courtship. The film's tension is less about detection than about whether ordinary people can read the signs in time, and it asks what social conventions make certain women legible targets for men like Mason.
