The String of Pearls (1850), p. 263

"To be sure."
"Well, when you left, Todd came, and after once looking in his face, I almost
forgot what happened, except that there was a madhouse and a man named
Watson."
"Watson?" said Colonel Jeffery, as he made a note of the name.
"Yes," added Tobias, "and Fogg."
"Good! Fogg, I have it. Now, Tobias, where did you encounter this Fogg and Watson?"
"That I cannot tell. I recollect trees, and a large house, and rooms, and a kind of garden, and some dark and dismal cells, and then my mind seems, when I think of all those things, like some large room full of horrors, and anything comes before me just like some dreadful dream. I recollect falling, I think, from some wall, and then running at my utmost speed until I fell, and then the next thing that I remember was hearing the voice of Minna in this house."
"One thing," said Captain Rathbone, "is pretty certain, and that is, that this
madhouse, if it were one in reality, must be in the immediate vicinity of London,
or else the strength of Tobias would not have enabled him to run so far as 10
London from it."
"Mrs. Ragg, I believe Todd told you that he had placed Tobias in a madhouse,
did he not ?" said the colonel.
"Yes, sir, he did, the wagabone!"
"Well, I am inclined to think that it was a madhouse—one of those private
dens of iniquity which are, and have been for many years, a disgrace to the jurisprudence of this country."
"If so, then," said the captain, "there will be no great difficulty in finding it
with the clue that Tobias has given us respecting the names."
"I will not be satisfied until I have rooted out that den," said the colonel, "but at present all our exertions must be directed to ascertain the fate of poor Ingestrie. Every circumstance appears really to combine in favour of the opinion of Johanna Oakley, to the effect that this Thornhill and Mark Ingestrie were the same."
"It does look marvellously probable," said the captain.
"Do you recollect any more, Tobias?" said Minna.
"Not clearly, Minna, and I am afraid that what I have recollected is not very clear,
but it was the dog that made an impression upon my memory. Many things are,
however, now each moment crowding to my mind, and I think that I shall soon be able to recollect much more."
"Not a doubt, Tobias. Do not attempt to strain your memory too far now; Things will come back to you gently, and by degrees."
"I have no doubt of that, sir, but—but—"
"But what, Tobias?"
"Oh, sir, you are quite sure—"
"Sure of what?"
"That when I least expect it, round the curtains of my bed, or from behind
some chair, or from some cupboard about twilight, I shall not see the hideous
face of Sweeney Tood, and feel his eyes glancing upon me?"
Poor Tobias covered his eyes with both his hands, as he gave almost frenzied
utterance to these words, and both Colonel Jeffery and his friend, the captain,
looked on with aspects of deep commiseration. The former, after the pause of a
few moments, to allow the renewed excitement of Tobias fully to subside, spoke
to him in a kind but firm voice.
"Tobias, listen to me. Do you hear me?"
"Yes, sir—oh, yes."
"Then I have to tell you that it is impossible Sweeney Todd can now come
upon you in the way you mention, or in any other way."
"Impossible, sir?"
"Yes, quite. He is now watched by the officers of justice, day and night. His house door is never lost sight of for a moment while he is within it, and
