The rain fell relentlessly, drumming on the roof. A flickering lamp cast shadows on the wall. Detective Miller, a tall man with sharp eyes, stood in the room. A woman lay on the floor, her body still. A single red rose lay beside her hand. The air was thick with the scent of perfume. An emerald necklace, broken and discarded, lay nearby. Miller knelt down and examined the scene. He knew this was no ordinary murder. The killer had left a message in plain sight.
