"By a merchant in what Comrade Maloney would call a tall-shaped hat. I spotted him at an early date, somewhere down by Twenty-ninth Street. When we dived into Sixth Avenue for a space at Thirty-third Street, did he dive, too? He did. And when we turned into Forty-second Street, there he was. I tell you, Comrade Windsor, leeches were aloof, and burrs non-adhesive compared with that tall-shaped-hatted blighter."

"Yes?"

"Do you remember, as you came to the entrance of this place, somebody knocking against you?"

"Yes, there was a pretty big crush in the entrance."

"There was; but not so big as all that. There was plenty of room for this merchant to pass if he had wished. Instead of which he butted into you. I happened to be waiting for just that, so I managed to attach myself to his wrist with some vim and give it a fairly hefty wrench. The paper was inside his hand."

Billy was leaning forward with a pale face.

"Jove!" he muttered.

"That about sums it up," said Psmith.

Billy snatched the paper from the table and extended it towards him.

"Here," he said feverishly, "you take it. Gum, I never thought I was such a mutt! I'm not fit to take charge of a toothpick. Fancy me not being on the watch for something of that sort. I guess I was so tickled with myself at the thought of having got the thing, that it never struck me they might try for it. But I'm through. No more for me. You're the man in charge now."
