Rain lashed against the broken window pane while a cold wind howled through the empty, dark and silent hallway. The silver knife rested deep within the victim's chest, spilling dark crimson blood across the white silk bed sheets. Detective Miles stepped over the velvet rope, glancing at the pale face of the man who had died tonight. No fingerprints marked the polished mahogany table, yet a single gold button lay beside the body on the floor. The butler trembled in the corner, clutching a linen towel while his eyes darted toward the locked study door. Someone had killed the lord of the manor before the midnight bell could ring across the foggy English moor.
