I assume this was one of those B movies made then.Usually shown in a double bill in the cinemas.I couldn't really call this a murder mystery as you see who the killer is from their first murder.As often happens in this type of thing the smaller parts are more interesting than the main leads.Leslie Dwyer is interesting here in a small role and nice to see Arthur Lowe in a small part years before Dad's Army.
