The niece of Kimber (Phillip Leaver), a wheel chair bound and irritable old man who lives in a country mansion, is sole heir to a fortune. However, Cynthia (Jean Lodge) is more interested in her beau Peter (Peter Lorimer), of whom Kimber disapproves. Cynthia vanishes without a trace, leaving Kimber the beneficiary. Cynthia's school friend Miss Frayle (Julia Lang), who works for the detective Dr Morelle (Valentine Dyall), decides to go looking for Cynthia herself and takes up a job at Kimber's house. She discovers some mysterious and potentially deadly goings on and calls in Dr Morelle...
This isn't that bad a film though can drag a bit at times. Dr Morelle treats Miss Frayle rather terribly which makes it hard to warm to his character. The twists at the end are good, but getting there can take some work. Dr Morelle was a long running character in BBC radio dramas though only made it to the silver screen this one time.
