He took out a piece of jewelry swinging ponderously at the end of a gold 
chain. It was circular, smooth gold on one side and white on the other. The 
white side was protected under a flattened glass dome. It had numbers written 
around the edge, and a couple of slender metal things like daggers, one longer 
than the other, joined at their hilts in the center. It made a noise like mice 
trying to eat their way through a wall in the middle of the night.
