"I don't," he said, "I don't. That's just it. That's the curious part of it, that I——"

He broke off deliberately, got up and stretched.

"I'll have a pipe, too," he said.

He went over to the mantelpiece, got his pipe, filled it and lighted it. As he held the match to the tobacco, bending forward with an enquiring expression, his eyes fell upon the green baize that covered Napoleon's cage.

Then suddenly he pushed it back over the cage.

I saw the person—if it was a person,—through the railings."

"If it was a person!" said the Father. "What do you mean by that?"
