Fear in the Night

One of those neatly constructed but slightly mechanical psycho-thrillers which make you feel as if someone is pushing buttons connected to electrodes in your brain. Geeson plays a young woman recovering from a nervous breakdown who is terrorised into wanting to kill the aged, deranged headmaster of the prep school where her husband (Bates) teaches. What she doesn't know is that Bates is in league with the headmaster's wife (Collins). There is a sporadically effective use of prowling camera movements and atmospheric sounds, but Hammer fans will soon recognise the plot as a thinly disguised reworking of A Taste of Fear, which Sangster scripted for Seth Holt back in 1961.
