Freezing rain lashed the tall glass windows of gloomy Blackwood Manor while Detective Miller stared at the twisted corpse below. Lord Harrington lay sprawled across his antique velvet Persian rug, a shattered crystal goblet resting near his cold, pale hand. The grandfather clock chimed midnight as acrid smoke from an extinguished silver candle drifted toward the freshly locked study door. A bloody smear marked the heavy brass wall safe, hinting that someone had fled with the secret will before escaping. Miller pulled on his leather gloves, fully aware that the ruthless killer was still trapped inside this dark, isolated mansion.
