“That’s only Tom’s joke, sir,” said Sam apologetically. “I’m not selling anything.”

“Oh, then you weren’t looking for me?”

“No, sir—yes, sir, I was, only——”

“The plot thickens! Only what?”

“I mean I was going to your office, but after I ran into you I thought there wouldn’t be any use going, and so I came in here. I didn’t know you were here, sir.”

Tom was enjoying Sam’s embarrassment hugely. “Better confess everything, Sam,” he said soberly, “if you want Mr. Hall to help you.”

“Eh?” said Mr. Hall. Sam frowned.

“Cut it out,” he muttered.

“Look here, Mr. Craig, your story interests me strangely,” declared the man. “You were looking for me, only you weren’t. Sounds a great deal as though you thought I was a dentist. By the way, how did you know who I was when we collided?”

“Tom told me that—I mean, he described you.”
