When Tom tackled Koswell the latter said positively that he knew nothing of the dress-suit case.

He said he had found the box on a stand in the hallway near Professor Sharp's door, and had used it because it suited his purpose.
"But you saw it had my name on it," said Tom.
"No, I didn't.

It was rather dark in the hall, and all I saw was that it contained pencils and crayons," answered Jerry Koswell.
"Well, I don't believe you," answered Tom abruptly.

"You did it on purpose, and maybe some day I'll be able to prove it." And he walked off, leaving Koswell in anything but a comfortable frame of mind.
Tom was curious to see how Professor Sharp would act after the affair.
During the first recitation the instructor seemed ill at ease, but after that he acted as usual.

Tom half suspected the professor still thought him guilty.
"Well, it was a pretty mean thing to do," soliloquized the fun-loving Rover.
