Murder at the Grange

A former police detective who is now a private investigator is approached by two elderly sisters, who say that someone is terrorizing them, and they think it's the ex-fiancée of one of the sisters, who they believe had killed their father years before. However, when it turns out that the man they suspected has been long dead, the detective has to look elsewhere for suspects--and their shady butler just happens to be a prime one.
