Pretty, neurotic newlywed Peggy (Judy Geeson) survives an attack by a leather-gloved, one-armed assailant the day before she is due to leave London to live with her husband Robert (Ralph Bates) who teaches at a posh boys school in the country owned by sinister headmaster Michael Carmichael (Peter Cushing) and his bitchy young wife (the lovely Joan Collins).

Once there, though, poor Peggy soon realises that, even though she is now miles from the city, she still isn't safe: the one-armed maniac appears to have followed her to her new home...

It shouldn't take seasoned fans of psychological thrillers very long to suss that the mysterious goings on in Hammer's Fear In the Night are intended to turn the protagonist completely insane, drive her to murder, or both. But although the film's plot doesn't earn many points for originality, being heavily reminiscent of the French thriller Les Diaboliques, director Jimmy Sangster delivers enough startling imagery (Cushing's shattered glasses; a gloved prosthetic arm) and well-handled scenes of suspense to ensure that the film is certainly never dull: from its wonderful opening credits sequence, in which the camera pans across the school to eventually reveal the legs of a man hanging from a tree, to its tense denouement, Fear in the Night is a solid slice of macabre entertainment.
