A highly enjoyable comedy crime drama, at times it verges on Carry On territory but thats no bad thing.
Ernie (Kenneth Connor) is told his rich uncle has died by a somewhat sinister solicitor (Donald Pleasance). Ernie heads off to his uncle's country pile with his mate Syd (Sid James), a lonely looking house in the moors. Ernie's fellow family members are a motley crew of weirdos. Then the deaths start happening...
Ernie, Syd and the rest, including the uncle's former nurse (Shirley Eaton) scramble to try and work out what is going on in the strange house and stop the murderer. However, they need to identify who it is first. Surely it must be one of the family members present or is it, in this house riddled with secret doors and passageways...
This is a fine film, most of the time it isn't laugh out loud funny rather than humorous and inventive but it does have it's slapstick and ridiculous moments especially with Connor and James. It has plenty of twists too, it works as a dark house crime drama as well.
