Rain slammed against the tall glass windows, washing away the ancient bloodstains that covered the cold marble floor below. Lord Harrington lay slumped over his mahogany desk, a golden letter opener buried deep inside his silent, still chest. Detective Vance pulled his damp coat tighter, staring intently at the bizarre, intricate silver clock resting beside the corpse. The pendulum was frozen completely in place, pointing directly toward the hidden velvet curtain across the dimly lit room. A single red rose rested near the body, its delicate petals carefully dusted with a strange, glowing white powder. "Nobody leaves this grand mansion tonight," Vance muttered softly, turning his sharp gaze toward the terrified, silent suspects.
