The String of Pearls (1850), p. 571

"It must be all right," thought Todd, "or he would not sing that song; but what good it can do him to get from his own cell into this, I cannot imagine. He would be equally confined here as there, and all his labour thrown away. But together, we may do something, I will speak to him. Yes, I think I will speak to him."
Todd still waited and lingered before he gave any intimation of his presence and knowledge of what was going on, and then the song ceased, and by the
renewed vigour with which the tenant of the next cell worked at the stone, it would seem that he had got very impatient at the length of time it took him.
Suddenly, the stone, which was about a foot square, shook so, that Todd withdrew from it, thinking that it would come out of its place altogether; and as it was evidently the object of the prisoner at the other side to push it through into Todd's cell, he thought it better to stand on one side, and let it come.
Suddenly, with a crash, it fell through, and then Todd spoke, for the first time, to the prisoner.

CHAPTER CXXXIIL.
THE PROGRESS OF THE OPERATIONS TO ESCAPE FROM NEWGATE.

"Who's there? Who are you ?" cried Tood.
"The deuce!" said a voice, from the adjoining cell. "Sold at last, after all my trouble. Confound you, why didn't you speak before, and save me the last hour's work?"
"What do you mean?" cried Todd. "I am a desperate man. Do not tamper with me Do you belong to the prison, or do you not?"
"I belong to the prison? I should think not. Don't you?"
"Oh, no—no—no—no."
"Why, you don't mean to say that you are a prisoner?"
"I am, indeed, and condemed to die."
"All's right then. Bravo! This is capital. I thought I was in the end cell, do you know, and that by working through the wall by the assistance of Providence always Bah! I can't get out of the old trade. I mean to say, that I thought I was working through a wall that would have taken me into one of the corridors of Newgate, and then there would have been a chance of getting off, you know."
"I do not know, and did not know," said Todd; "but if there be really any chance of escape, I am a desperate man, and will risk anything for it. Only say that you will help me."
"Help you? Of course I will. Do you think I am in love with these cold walls? No, I will get a light in a moment, and we can then have a look at each other. Are you in fetters?"
"I was, but I have a file, and have succeeded in freeing myself from them completely. Are you?"
"Yes, but I have muffled them with some pieces of my clothing that I have torn up for the purpose, and please the Lord they will make no noise."
Todd was rather amazed at the religious expressions of the other prisoner; but he forbore to make any remark concerning them, and as something had been said about getting a light, he resolved to wait patiently until it was procured, when he would be able to see who it was that chance had so very strangely thrown him into companionship with.
"You see," added the other prisoner, "a religious lady left me some tracts, and as I told her they did not allow light here, she was kind enough to smuggle me in some phosphorous matches, in case in the night I should wish to read."
"Very kind of her," said Todd.
"Oh, very. Let us praise the—Bother, I shall never get out of the habit of chaunting, I do believe."
