Rain hammered the manor roof. Detective Mara Cole stepped inside. The heavy oak door closed. A body sprawled near stairs. Blood darkened the Persian rug. No murder weapon was visible. The air smelled of violets. The grandfather clock struck one. Every window was locked shut. She crouched beside the body. His eyes stared at nothing. His pocket held a note. She removed it with tweezers. Five words were scrawled there. "Find the clockmaker," it said.
