The fog arrived before dawn, swallowing the road to Blackthorn. Inside, the house smelled of lilies, smoke, and wet wool. Detective Mara Voss found the body beneath the grandfather clock. Lord Blackthorn lay facedown, one hand reaching toward the fireplace. A silver letter opener protruded neatly between his shoulder blades. The clock had stopped at precisely seventeen minutes past midnight. Outside the study, six guests waited beneath the flickering chandelier. Each claimed they had heard nothing during the night’s storm. Yet someone had locked the study door from the inside. Mara examined the windows, finding both latches fastened and undisturbed. Then she noticed soot scattered across the dead man’s collar. The fireplace was cold, but the ashes concealed something warm. She drew out a key, still warm against her glove. Its bow bore the initials of the house’s newest guest.
