The rain fell hard against the window pane, masking the sound of the gunshot that echoed through the dark hall. Detective Miller stepped over the shattered glass, his eyes fixed on the crimson pool spreading across the old Persian rug. The victim lay motionless near the fireplace, a silver dagger protruding from his chest at a peculiar, deadly, sharp angle. A cold wind howled through the open door, carrying the scent of pine needles and fresh blood into the room. On the mantelpiece, a single white envelope rested, bearing the name of the prime suspect in elegant, looping black ink. Miller knew this dark night would change everything, for the killer had left a message that only he could understand.
