Rain lashed the manor windows while thunder shook the walls. A scream echoed down the corridor just before first dawn. The old butler discovered Lord Ashworth slumped over his desk. A silver letter opener protruded from the dead man's chest. The guests gathered downstairs whispering about secrets and old grudges. Detective Mara Hale arrived before the police could contaminate evidence. She studied every face and trusted absolutely none of them. Somewhere inside that house a killer was still quietly watching.
