"I cannot tell you," said the boy, "I cannot tell you what I do not know."

"But, you have some idea, probably. Come, we will make it worth your while, and thereby protect you from Sweeney Todd. We have the power to do so, and all the inclination; but you must be quite explicit with us, and tell us frankly what you think, and what you know concerning the man in whose fate we are interested."

"I know nothing, I think nothing," said Tobias. "Let me go, I have nothing to say, except that he was shaved, and went away."

"But how came he to leave his dog behind him?"

"I cannot tell. I know nothing."

"It is evident that you do know something, but hesitate either from fear or some other motive to tell it; as you are inaccessible to fair means, we must resort to others, and you shall at once come before a magistrate, who will force you to speak out."

"Do with me what you will," said Tobias, "I cannot help it. I have nothing to say to you, nothing whatever. Oh, my poor mother, if it were not for you—"

"What then?"

"Nothing! nothing! nothing!"

It was but a threat of the colonel to take the boy before a magistrate, for he had really no grounds for so doing; and if the boy chose to keep a secret, if he had one, not all the magistrates in the world could force words from his lips that he felt not inclined to utter; and so, after one more effort, they felt that they must leave him.
