The old Victorian manor loomed against the moonless winter sky. A chandelier flickered above the freshly discovered corpse in silence. Detective Blackwood arrived first, stepping carefully past bloodied antique furniture. Lord Harrington, beloved patriarch of the entire family, lay dead. Every window and door had been locked from the inside. There were no witnesses, no struggle, and no clear motives either. Six guests remained trapped inside, each hiding dangerous, bitter secrets. Someone here had killed him; Blackwood intended to find out. The blizzard howled beyond the walls, sealing them all together tonight. As the grandfather clock struck midnight, the investigation quietly, ominously began.
