At this point Miss Pao stopped talking and swiveled her eyes in the 
direction of Chang, who was standing quiescently with his hands clasped behind 
his back, staring down at the floor as if his thick neck had finally given way 
under the weight of his head. Miss Pao cleared her throat once, twice, three 
times, and suddenly Chang came awake. "Excuse me, Your Honor," he said, 
bowing to Judge Fang. He rummaged in a large plastic bag and withdrew a 
gentleman's top hat in poor condition. "This was found at the scene," he 
said, finally reverting to his native Shanghainese.
