Rain drummed against the glass while Arthur poured his drink. One single bullet had shattered the heavy crystal decanter yesterday. He stared at the dark crimson stain on the rug. Nobody heard the silent shot during the loud thunder storm. His brother lay dead inside the locked and frozen cellar. Suspicion lingered in the air like a thick winter fog. Every guest had a hidden motive for this terrible crime. The butler wiped a silver knife with a silk cloth. Fear settled deep within the hollow bones of the house. This long night would surely reveal a very cold killer.
