"Yes."

"Then you know the advice that Lecoq gave his men when they wanted to disguise themselves. 'Change the eye,' he said. 'The eye is the important factor in disguise.' He was right and I have spent some time practising the maxim. Try to look stupid and your eyes will deaden. Not that way," and he caught my arm as I made for the lobby. "The back entrance for ours unless we want to land in a cell at the police station."

We sneaked out into the back yard, around the building, and out into the street, where a motor car was waiting.

"All right, Wilkins. Full speed ahead," said McKelvie as we got in. With a jerk we were off toward the Park.

"Now," I demanded, "what's it all about?"

"You've got your pistol with you?" he asked, and when I answered in the affirmative, he went on, "Don't use it unless I give you leave. The less shooting the better for us, I expect."

"Is it Lee?" I inquired.

"Yes. My offer of reward hustled things up a bit." McKelvie leaned forward and called out, "Faster, Wilkins. We'll never make it at this rate."

"He's in danger, then," I said, as we tore around corners and down side streets to avoid the cops.

"Yes. But let me begin at the beginning. Wilkins got onto the track of a mysterious taxi that had been seen on Mott Street about four-fifteen the afternoon of October the eighth, and while he was hanging around one of those Chinese joints, he saw two toughs lounging down Pell Street, and evidently discussing the reward, since one of them was waving the hand-bill in the other's face. Wilkins followed them into an eating-house and by securing a table next to them, overheard their conversation. It seemed that they had identified Lee as the young man they had kidnapped and they were weighing the respective merits of giving their information to me or blackmailing the 'old man,' as they called whoever had hired them. The younger tough was for telling me, but the older one seemed to think they could make more from the 'old man.' Whereupon the younger one declared that the old fellow was stingier than hell and reminded his companion that Hi Ling had tipped them that the young man was to disappear that night, after the boss's visit at one o'clock. When the men separated Wilkins followed the younger one and by many judicious hints and the added compensation of some money and promised immunity from the police, he got the rest of the story.
