The old mansion stood silent beneath the stormy midnight sky. Rain lashed the windows as thunder rattled the wooden doors. Detective Eleanor Gray stepped into the grand marble entrance hall. Water dripped from her coat onto the polished black floor. A single white candle flickered atop the long oak table. Lord Percival Whitmore lay dead beside the shattered crystal glass. His wide eyes stared up at the painted ceiling above. A faint smell of bitter almonds filled the entire room. Eleanor knelt beside the body and studied the carpet fibers. Someone had locked all the doors from the inside tonight. The killer was still hiding somewhere inside this very house.
