I saw this on video as "Never Take Candy from a Stranger," under which title it was apparently released in the U.S. It was the one serious film produced by Hammer Films, famous for its Gothic horrors, and I found this much more suspenseful, as well as much better made, than the lot of them. It begins with small tensions of frustration and mild dislike among members of the academic community in a small town and gradually, subtly builds to an atmosphere of dread that catches in the throat. Every character, down to the bit parts, has something of interest to say, and what they say and do, and how their actions combine, lead step by step to the harrowing conclusion. The only fault is the over-simplicity of its social viewpoint, as expressed by the main character and justified by the events of the story, which are by no means unbelievable but not inevitable either. Apart from that, I thought it was a first-class B-picture, a small film in the good sense, compact and economical, with all its resources, human and otherwise, firmly in hand. Also, it has the grey photography that once used to give films of this type the aura they needed: the grey of rain and fog and dusk and uneasy feelings.
