An expensive watch was stolen from a hotel room. The maid stated she found the room empty when she went in to clean at 2:00 PM. The guest swore he left the watch on the nightstand when he went to breakfast at 8:00 AM. Detective Chen arrested the maid after noticing a detail on the nightstand. What was it?
A thick layer of dust with no ring
If the watch had been sitting on the nightstand since 8:00 AM, there would be a clean spot or dust ring underneath it, but the dust was completely undisturbed.
