"I, personally, have got nothing to do with the Doctor's wickedness in the matter. In my opinion that is Pratt's affair."

But I felt pretty sure Pratt wouldn't bother about it.

"Anyway," said Peters, "I now return Pratt his pencil-sharpener, and there my duty as the detective of the case ceases. Sherlock Holmes often did a tremendous deed and only told the way he'd done it to Watson. And so it is here. It is not my work to bring the Doctor to justice, and I'm not going to try to do it."

I said he was right, because, while he was bringing the Doctor to justice, he might get expelled, and that wouldn't be much of a catch for anybody.

So the first thing after morning school we went to Pratt, and Peters put on his Holmes manner and said—

"Well, Pratt, no news of the missing pencil-sharpener, I suppose?"

And Pratt said, "Mine or the Doctor's?"

And Peters said, "Yours."

"Yes, there is," said Pratt; "I found it in my lexicon two days ago. I'd marked a word with it and clean forgotten. So that's all right."

"Not so right as you might think," I said.
