The old clockmaker lay motionless behind his cluttered workbench, surrounded by scattered gears and shattered glass covering everything now. Detective Marina Cole stepped cautiously through the broken back door, her flashlight cutting through the dusty morning light behind her. Someone had written a message in blood across the eastern wall, letters dripping slowly downward like tears from frightened eyes. The young apprentice had found the body exactly thirty minutes earlier while opening the shop for daily business today. Nothing here appeared random to Cole; every gear, every shard of glass seemed placed deliberately, yet the full picture was just beginning. A single pristine pocket watch rested upon the victim's chest, its meticulously crafted brass hands frozen permanently at midnight told Cole everything she needed to know about this particular case now.
