The String of Pearls (1850), p. 687

"It's coming now," thought Todd. "It's coming now. They will tell him where I am."
The next words that were spoken, were uttered in a tone of voice that did not reach his ears. It was the old man who had spoken, and he did not utter his words so clearly as his younger companion ; and although he tried his utmost to hear what he said, he could not possibly make it out, and he remained in a perfect agony of apprehension.
"Very well," said the officer in the police-barge, who had conducted the brief conversation. "It is a miserable night. Give way, my men. Steady there. Put the light out."
In an instant the light was lowered and extinguished, and the darkness that reigned upon the surface of the Thames was like a darkness that could be felt. It was difficult to conceive that it was not really tangible.
"Are they coming back?"
That was the question that Todd asked of himself, as he grasped; to steady himself, the heavy piece of iron that belonged to the pile-driving machine. He listened most intently, until it was positively painful to do so, and he began to fancy all sorts of strange noises in the air and from the water. In a few moments, though, an actual splashing sound put to route all imaginary noises, and he felt convinced that the boat with the police was slowly returning towards
the barge in which he was concealed.

There was, to be sure, still a hope that they would pass it; but it was only
a hope.
Oh, how awfully full of apprehension was each passing moment now. It might be that the police-galley was only going quietly back to its proper station, after overtaking the wherry; but then it might be quite otherwise, and the doubt was terrific. While that doubt lasted, it was worse than the reality of danger.
And now it was quite evident to the perception of Todd that the police-boat was close to the barge, and he heard a voice say—
"Is that the pile-driving barge?"
"Yes, sir," replied some one.
"And they leave it, I suppose, as usual?"
"No doubt, sir."
"Well, pull alongside, and a couple of you jump in and see if all is right. People leave their property exposed to all sorts of depredations, and then blame us for not looking after it; Mind how you go, my men. Don't run foul of the barge."
"No, sir. All's right."
From the moment that this conversation had begun, Todd had remained crouching down in the barge, like a man changed to stone. He heard every word—those words upon which hung, or seemed to hang, his life, and his grasp upon the massive piece of iron tightened.
The police-boat gradually advanced, and finally just grated against the side of the barge.
A sudden thought took possession of Todd. With a yell, like that of a madman, he, with preternatural strength, moved the heavy mass of iron, and in one moment toppled it over the edge of the barge.
Crash it went into the police-galley. There was then a shriek, and the men were struggling in the water. The piece of iron had gone right through the boat, staving it to pieces. It filled and sank.
"Help—help!" cried a voice, and then all was still as the grave for a few moments.
"It is done," said Todd.
"Help! mercy!" said a voice again, and a dark figure rose up by the side of the barge, clinging to it.
Todd drew one of his pistols. He levelled it at the head of the figure. He was upon the point of pulling the trigger, when it struck him that the flash and
