"What—what?—eugh! eugh!" coughed the old doctor; "a boy, Mr. Fogg, a mere boy. Dear me! I—I—eugh! eugh! eugh! My cough is a little troublesome I think, to-day—eugh! eugh!"

"Yes, sir," said Fogg, with a deep sigh, and making a pretence to dash a tear from his eye; "here you have a mere boy. I am always affected when I look upon him, doctor. We were boys ourselves once, you know, and to think that the divine spark of intelligence has gone out in one so young, is enough to make any feeling heart throb with agony. This lad though, sir, is only a monomaniac. He has a fancy that some one named Sweeney Todd is a murderer, and that he can discover his bad practices. On all other subjects he is sane enough; but upon that, and upon his presumed freedom from mental derangement, he is furious."

"It is false, sir, it is false!" said Tobias, stepping up. "Oh, sir, if you are not one of the creatures of this horrible place, I beg that you will hear me, and let justice be done."

"Oh, yes—I—I—eugh! Of course—I—eugh!"

"Sir, I am not mad, but I am placed here because I have become dangerous to the safety of criminal persons."

"Oh, indeed! Ah—oh—yes."

"I am a poor lad, sir, but I hate wickedness; and because I found out that Sweeney Todd was a murderer, I am placed here."

"You hear him, sir," said Fogg; "just as I said."

"Oh, yes, yes. Who is Sweeney Todd, Mr. Fogg?"

"Oh, sir, there is no such person in the world."
