The detective arrived precisely midnight, finding Hawthorne Manor bathed in unnatural silence despite roaring storm outside wrought iron gates. Inside, Lord Ashford lay sprawled across library floor, antique dagger protruding theatrically from his tailored dinner jacket like punctuation mark. The household staff huddled near fireplace, their faces pale masks concealing secrets, guilt, and poorly rehearsed grief for questioning detective. Nobody touched anything, Mrs. Whitmore declared firmly, though fresh footprints clearly marked bloodstained rug beneath victim awaiting forensic analysis tonight. Detective Marlowe knelt beside body, noticing missing cufflink, smudged lipstick, and faint scent lingering perfume that definitely did not belong.
