When Sarah Lawson's wealthy employer disappears, she turns for help in locating him to her estranged husband, mystery writer Richard Gale.
The police butt in quickly, of course, but mostly because someone we don't see has been murdered. Not only does the logic of the characters escape me, bt so does the way this movie is produced. Likely many cheap British quota quickies, it's shot cheaply on poorly decorated sets. Because it's almost entirely talk, it's shot mostly in medium two-shot, occasionally varied by having a third person present, or pausing for a poorly lit location shot of a patch of dirt at night. Gale and Miss Lawson wander about, accumulating clues, while the police are hard at work, mostly Superintendent Duncan Lamont chatting with his sergeant Nigel Green in a mostly bare set which, I believe, is meant to stand in for a precinct office.
There is a brief encounter with the local drunken half-wit, played by Claude Dampier; Dampier, a comic who was often billed as 'The Perfect Idiot'. Whether his appearance here is meant to prove the accuracy of that billing or to demonstrate a sense of irony is left as a problem for someone who cares.
