Rain tapped quietly against the ornate windows of Blackwood Manor. A grand chandelier flickered as thunder groaned somewhere far away. Four guests exchanged wary glances, each clutching a delicate teacup. The butler, stiff and silent, lingered near the velvet curtains. A scream shattered the calm, echoing down the marble-tiled hallway. All conversations died; porcelain cups rattled on their saucers with fear. Footsteps hurried to the library, drawn by chilling, desperate cries. They found the host sprawled lifeless, crimson pooling beneath him. A letter opener gleamed cruelly, gripped tight in the wound. The butler closed the doors, trapping suspicion in the room.
