Rain hammered the dark windows. Thunder shook the old mansion. A scream cut through midnight. Guests gathered inside grand hall. Lord Ashcroft was not breathing. Blood pooled beneath his chair. His wine glass smelled bitter. The clock stopped at twelve. Detective Mara arrived too late. She studied the silent room. Everyone claimed they heard nothing. But someone hid a knife. The killer stood among them.
