The fog arrived before dawn, swallowing the manor and grounds. By breakfast, someone had murdered the master of the house. His body lay beneath the clock, which had stopped ticking. Blood darkened the carpet beside his outstretched, carefully manicured hand. Detective Mara Vane studied the room without crossing its threshold. Every window was locked, and the fireplace held cold ashes. Behind her, the household gathered silently along the narrow corridor. Each face betrayed something different: grief, fear, anger, calculated indifference. Only the youngest daughter seemed genuinely surprised to see Mara. Three days earlier, she had summoned Mara with one warning. “Someone in this house intends to kill my father tonight.”
