The velvet curtains hung heavy and still while a single spotlight flickered across the cold body on the wooden floor. Detective Miller stepped over the yellow tape and adjusted his glasses to see the strange mark on the dead man. Rain drummed a frantic rhythm against the skylight as the mansion remained silent except for the ticking of a clock. Nobody heard the scream during the thunder because the storm was loud enough to hide the sound of a struggle. He found a golden key tucked inside the victim's pocket and wondered which door in this house it might unlock. The butler stood by the marble fireplace with trembling hands while he watched the policemen search through the dark library. Something felt wrong about the way the wine glass lay shattered near the velvet chair in the middle of room. Every guest had a reason to want the old billionaire dead before he could sign the new version of will. The game had finally begun and the killer was likely still hiding somewhere inside the shadows of this ancient estate.
