Rain poured heavily outside the old Victorian manor while a grandfather clock chimed midnight in the empty, shadowy oak library. Lord Blackwood sat completely motionless behind his mahogany desk, an ornate silver dagger protruding deeply from his embroidered velvet chest. Detective Miller stepped carefully across the Persian rug, clutching his wet umbrella while examining the shattered glass beside the hearth. A single smeared footprint marked the polished wooden floor, leading directly toward the heavy red curtains concealing the secret door. The killer was clearly still inside the locked estate, waiting quietly in the suffocating darkness for the storm to pass.
