The rain stopped at midnight, leaving Blackthorn House silent except for the clock and the slow dripping of water overhead. Inspector Mara Venn found Sir Julian at his desk, his right hand clutching a silver key, his left hand empty. There was no wound, no weapon, and no pulse, only the faint scent of almonds rising from his cold tea. Nothing in the study seemed disturbed, yet the window stood open and wet footprints crossed the carpet toward his chair. On the blotter lay a dinner invitation for tomorrow, naming six guests, with a seventh neatly added in violet ink. Mara read the seventh twice; only her dead mother had ever called her that, and never within earshot of strangers. When Mara went downstairs, the guests waited beside a cold fireplace, five pale faces turning toward her in perfect silence. Before Mara could speak, the lights went out, and someone standing behind her whispered her childhood name in the darkness.
