After the museum closed, a silver pocket watch vanished bizarrely from a locked display case. Starting with the undamaged lock, velvet cushion impressions, chain clasp condition, and the blackout timeframe, Gu Lin gradually rules out outside theft through the back door's magnetic sensor, mud trace components, gray-blue fibers, and brass shavings. In the end, everyone discovers the pocket watch hidden inside the floor clock base and pieces together how Wei Ning fetched the spare key, unlocked the case, took the watch, relocked it, and staged the escape trace—closing the entire evidentiary loop.
