The String of Pearls (1850), p. 573

"Here it is," said Todd; "you work upon one leg, and I will work upon the other, for I have two files here, although one of them is a little blunted by the work it has already done. Yet it will help, and time is every thing."
"It is," said Lupin. "Work away, for I am not able to think of anything until I am free of these confounded irons."
They worked in real earnest, and to such purpose, that in a much less space of time than anybody would have thought it possible to accomplish the process in, the fetters of Mr. Lupin dropped from him, and, like Todd, he stood so far free from restraint.
"Now," he said, "I have some first-rate picklocks, and if providence—Tush! tush! I mean if we are lucky, we shall get on capitally. The next thing we have to do is, to get out of here, and by far the shortest way is to work through the wall. Have you any other tools beside the files, for they are not much use now to us?"
"Yes, a chisel."
"A chisel? Oh, my friend, you are indeed a wonderful man. A chisel? What may not be done with a chisel! A strong, good chisel, too. Oh, if we do not chisel our way out of Newgate now, it will be very hard indeed. Come, you shall see an old hand at work. Perhaps you have not had much experience at prison-breaking?"
"Certainly not," said Todd.
"Well, this will be a good lesson to you. Now you will see how nicely I will get one of these old square blocks of stone out of its place.
Todd smiled grimly. Perhaps he thought he could have given the Reverend Josiah Lupin a good lesson in some things; but at that time he was only too happy to meet with a companion who promised such great things in the way of immediate escape.
Certainly Mr. Lupin showed great dexterity in handling the chisel, with which he had been furnished by Todd; and in a much less space of time than any one would have thought the work could have been performed in, he had loosened the stone in the wall that he wished to dislodge.
"Let us both push it," he said, "and we shall get it through easily."
"But it's fall will make an alarm," said Todd.
"Oh, no. The distance is too short, and it will go down easy. Now for it."
They pressed upon the stone both of them, and by a skilful joggling movement, Lupin got it to move along until it was beyond its centre of gravity, and then, with a heavy bump, down it went on the other side. They both now paused for some moments, and spoke not a word, for they were anxious to discover if the fall of the stone into the passage beyond the cells had made any noise sufficient to attract the attention of the prison officials. All was still.
"It's as right as possible," said Lupin. "They are asleep, the greater part of them. The pretended vigilance in this place, and the sleepless watchfulness, is all a fudge. Turnkeys, and police officers, and Governors of Newgate, are but flesh and blood, and they will take things easy if they can."
"You are quite a man of the world," said Todd.
"Oh, yes; I have seen a little of it. But I say, Master Todd, deal candidly with me now. Have you not some secret hoard of cash, upon which we can make ourselves comfortable, when we get out of this mousetrap? I have not a penny piece; but you ought to have something, I should say. I don't mean to say but that I had money, but it was not hidden, and the police have got hold of that. If I were acquitted, they kindly said they would let me have it. But if found guitly, of which they did not entertain the smallest doubt, I could not want it."
"Curses on them!" said Todd; "they had enough of mine to have made us both rich men—very rich men. Oh, that I had been off a month ago!"
"Don't fret about that. We are all in the hands of a gracious provi—Psha! I am forgetting again. Whatever you do, Todd, in this world, don't
