Rain hammered the manor windows as the butler discovered Lord Ashworth lying dead beside the shattered conservatory glass at midnight. Detective Mara arrived before dawn, her coat soaked, and knelt beside the body without touching the silver letter opener nearby. No footprints marked the wet terrace, yet the French doors stood open, swinging gently in the cold morning wind outside. A single bloody fingerprint smeared the victim's collar, and somewhere upstairs, a clock chimed thirteen with chilling and deliberate finality.
