“You left the pig alone in the alley by itself?” asked Philo Gubb.

“Yes, sir!” said Mr. Smith. “I found an alley fence that had a staple in it, and I tied one end of the whipcord to the staple and went down the alley to find a barn I could put Henry in. About the fifth barn I tried I found a place for Henry and then I went back to get him, and he was gone!”

“And no clue?” asked Mr. Gubb.

“This tag end of the rope,” said Greasy Gus. “And that’s all I know about where Henry went, but my idee is somebody come along and seen him there and just thought he’d have a pig cheap.”

“It’s a pretty hard case to work onto,” said Mr. Gubb doubtfully. “Somebody might have come along with a wagon and loaded him in.”

“Sure!” said Mr. Smith. “No telling at all. That’s why I come to you. If he was where I could fall over him, I wouldn’t need a detective, would I? And if you find Henry I’ll just give you these four five-dollar bills. I’m no millionaire, but I’ll blow that much for the satisfaction of getting back at Three-Finger Watts. Is it a go?”

“Under them certain specifications,” said Mr. Gubb, using the exact words he had used before, “I can take up the case and get right to work onto it.”

Mr. Smith shook hands to bind the bargain and departed.

He had hardly disappeared before Mr. Alibaba Singh opened the door cautiously, put his head inside and then entered.

“I thought that man would stay forever,” he said with annoyance. “He isn’t in any way interested in my affairs or in the affairs of Mrs. Henry K. Lippett, is he?”
