The body lay on the cold floor. A single clock ticked in the dark. Detective Aris stepped into the silent room. Rain lashed against the window like whispers. A silver pocket watch lay near the hand. Its hands were stopped precisely at midnight. He noted the lack of any visible wound. Only a small, dark stain on the collar. A faint scent of violets hung in the air. A gloved hand had left a note nearby. It read, simply, "You knew what happened." His own reflection stared back from a mirror. Then, he saw the small, bloody glove.
