The rain stopped at midnight, and Blackthorn Manor rose above the valley, shining beneath the moon like a drawn blade. Inside, the guests were still dancing when the library bell rang twice, though nobody had touched its old, frayed rope. Detective Mara Venn found the host behind his desk, still seated upright, with a silver letter opener between his ribs. His champagne waited beside him, untouched, and a single white rose lay wilting across the broad green leather desk blotter. The door was locked from within, every window latched, and the only key rested inside the dead man's waistcoat pocket. Mara was reading his unfinished note when somebody behind her whispered her name, mimicking the voice of her dead sister.
