We moved Wu and his servant and stood in the doorway. Craig gave the rope a yank.

Instantly there was an explosion. A concealed shotgun in the wall fired, scattering shot all over the front of Wu's table, just where we had been standing, knocking over and breaking vases, scattering papers and in general wrecking everything before it.

"So, that's it," whistled Craig. "You fellows can come back now. Two of you men I'm going to leave here to watch the place and make other arrests if you can. Come on."

With Kennedy I left the tenement while the sergeant marched the prisoners out, and we drove off with them. Quite a crowd had collected outside by the time we came out. Among them, naturally, were many Chinamen, and we could not see two of them hiding behind the rest on the outskirts, jabbering in low tones together and making hasty plans. As we clanged away down the street they followed more slowly on foot.

Common humanity dictated that we take Wu first of all to a hospital and get him fixed up and to a hospital we went. Kennedy and I entered with our prisoners, closely guarded by the police.

Craig handed Wu over to two young doctors and a nurse. By this time Wu was very weak from loss of blood. Still he had his iron nerve and that was carrying him through. The two young doctors and the nurse had scarcely begun to take off Craig's rude bandage to replace it properly, when a noise outside told us that a weeping and gesticulating delegation of Chinese had arrived.

"Keep 'em back," called one of the doctors to an attendant. The attendant tried to drive them away, but nothing could force them back more than an inch or two as, in broken English, they sought to find out how Wu was. Their importunity proved too much for only one attendant. Still gibbering and gesticulating, the crowd brushed past him as if he had been a mere reed. The attendant raged about until he lost his head. But it was no use. There was nothing for him to do but to follow them in.

Kennedy by this time had finished talking to the doctors and handing Wu over to them. They had taken him into a room in the dispensary. Just then the chattering crowd pushed in, some asking questions, others bewailing the fate of the great Wu Fang. They were so insistent that at last one of the doctors was forced to demand that the police drive them out. They started to push them back.

In the melee, one of their number managed to get away from the rest and reach the doorway to the emergency room. He was, as we found out later, dressed almost precisely like Wu, although he had on a somewhat different cap. In build and size as well as features he was a veritable Dromio.

The other Chinaman drew back behind the screen which hid the doorway to the emergency room and concealed himself.
