The clock struck midnight as the rain began falling hard. A single lamppost flickered, casting long, eerie shadows. Dr. Aris found the body in the locked study. The victim's hand still clutched a broken pocket watch. A faint scent of roses hung in the stagnant air. No footprints marked the plush, crimson carpet anywhere. The window was bolted from the inside, absolutely secure. Aris knelt and noted the man's peaceful expression, strange. A silver locket lay open on the mahogany desk. Inside, a photograph showed the doctor laughing with someone. The killer was likely someone the victim trusted deeply. But who would want a gentle watchmaker dead now?
