Heavy rain battered the tall windows of the grand library. Lord Sterling lay dead upon the dark crimson Persian carpet. A sharp silver dagger protruded from his motionless tweed vest. Detective Vance stepped carefully around the widening pool of blood. He adjusted his wet leather gloves and surveyed the room. The heavy brass clock had stopped ticking just before midnight. Two crystal glasses sat completely empty near the roaring fire. Faint muddy footprints led directly toward the closed velvet curtains. Vance slowly drew his revolver and approached the dark alcove. Someone was still breathing quietly behind that thick red fabric.
