The midnight rain lashed against the old manor’s windows like a thousand tapping fingers. Detective Harlow arrived, her headlights cutting through the gloom. The victim, Sir Alistair Croft, lay sprawled on the oriental rug. A single, tarnished silver key rested just beyond his outstretched hand. The library smelled of old paper, whiskey, and something terribly coppery. Every clock in the grand house had stopped at precisely eleven. The family portraits on the walls seemed to watch her with judgment. A half-empty glass of scotch sat on the mahogany side table. The back door was unlocked, but the alarm system was mysteriously disarmed. Harlow knew the killer was still here, hiding in the shadows.
