After opening titles of sinister hypnotic music and swirling water, we're in a London apartment where Michael Cornforth, a writer, (Griffiths Jones) is making ready for bed. The next morning when he awakes he's not only fully dressed and in a completely different place in the sticks – he's also holding a gun! After a bewildered nosey round the gaff, this being a black and white second feature, he of course finds a dead body - in the kitchen. Two Rank charm school types, Jean (played by Patricia Laffan) a bossy nosey parker type certainly, a lesbian possibly – and Marian, a beautiful trance like possibly drug addicted living doll – call round on, of all things, a walking holiday. They're soaked to the skin (it is, after all ,raining) and seeking shelter. This being Britain in the 1950, Cornforth can't tell them to do one so he only goes and lets them in doesn't he. After lots of farcical trying to keep them out of the kitchen stuff while not appearing to be totally odd - and Jean informing Cornforth that her friend is "very nervy and imaginative – always expecting to find bodies under the bed" - Marian upsets the Saxa salt and one textbook scream later discovers the corpse. Not unnaturally the two girls try and bail out. Cornforth prevents this at gunpoint – and then things begin to get really silly. He wants to talk to Jean who then simply goes off with him for a nice chat while leaving Marian in the bedroom without explanation like a naughty child. Cornforth says he can prove he was in London last night as his neighbour Mungo Jerry – or Peddy – saw him. Jean then goes from "You murdered him (not Mungo) didn't you?" to "I can take care of Marian. No one believes her anyway" in the blink of an eye. Why I'm not sure. It can't be Cornforth's charisma. Later on Jean informs Cornforth that she's had Marian sent to hospital. "They've got her under heavy sedation. She'll be out for 24 hours." With friends like that?
All in all Hidden Homicide – in terms of characterisation, plotting and probability - charters new waters of terribleness even by the standards of the British black and white 1950s B movie.
