# Blackwood Manor Rain hammered against the ancient windows of Blackwood Manor tonight. The clock struck midnight just as the lights went out. Eleanor Whitmore screamed once, then silence consumed the dark house. When the candles returned, she lay dead upon the floor. A pearl necklace was missing from her pale, cold throat. Five guests remained downstairs, each with motive and secrets untold. The front door was bolted shut from the inside completely. Someone among them was a killer, hiding in plain sight. Detective Harlow arrived just before dawn, studying every single face. He knew this case would test his sharpest, keenest instincts.
