The rain lashed stained-glass windows of Blackthorn Manor as the head housekeeper turned the brass lock on the library’s door. Inside, prospective heir Elias Voss slumped over the antique chessboard, a cold letter opener jutted horizontally from his bloody back. Martha’s teacup slipped from her trembling grasp, shattering across the oriental rug that had hung beneath the manor’s family portrait. A single white chess queen rolled slowly off the edge of the table, coming to rest beside her scuffed slipper. Footsteps echoed down the upstairs hallway, heavy and deliberate, heading straight for the locked library door she had just entered.
