The String of Pearls (1850), p. 612

During his career in the shop in Fleet Street, he had collected a number of watches from the pockets of the murdered persons, but he had always been afraid to attempt the disposal of the best of them.
The fact was, that at that time everybody had not a watch as at present. It was an expensive article, and Mr. So-and-so's watch was as well known as Mr. So-and-so himself; so that it would have been one of the most hazardous things possible for Todd to have brought suspicion upon himself by going about disposing of the watches of his victims. It was the same, too, with some other costly articles, such as rings, lockets, and so on; and as he had realised as much money as he could previous to his arrangements for leaving England, Todd had left some of this description of property to perish in the fire, which he hoped to be the means of igniting in old Fleet Street upon his departure.
Now, as he crept along by Tottenham-Court Road, he mused upon the state of things.
"If," he muttered, "I could only get into my late house in Fleet Street, I know where to lay my hand upon portable property, which was not worth my consideration while I had thousands of pounds in gold, but which now would be a fortune to me in my reduced circumstances. If I could but lay my hand upon it!"
The more Todd thought over this proposition, the more pleased he was with it; and by the time he had indulged himself with two more glasses of brandy, it began to assume, to his mind, a much more tangible shape.
"If it may be done," he said, "it surely may be done. If I could only make my way in the church it might be done well, and surely one of these picklocks that I have about me might enable me to do that."
The picklock he alluded to was one that he had put in his pocket to accommodate Mr. Lupin, when they were both so intent upon their escape from Newgate, and when Mr. Lupin was foolish enough to believe that Todd really had two thousand pounds buried in Caen Wood, Hampstead. There was one thing, however, which made Todd pause. He did not think he was sufficiently disguised to venture into the locality of his old residence, and, unfortunately for him, he was rather a peculiar-looking man. His great chance, however, was, that in Fleet Street surely no one would now think of looking for Sweeney Todd.
"I must be bold," he said, "I must be bold and resolute. It will not do to shrink now. I will buy a knife."
This was a pleasant idea to Todd. Buying a knife seemed almost like getting half-way to his revenge, and he went into an obscure cutler's shop, and bought a long double-edged knife, for which he gave two shillings. He then carefully concealed it in his clothing.
After this, he hit upon a plan of operations which he thought would have the effect of disguising him. At that period, wigs were so commonly worn that it
was nothing at all particular for a person to go into a wig-makers, and select one—put it on—pay for it—and go away!
"Yes," said Todd, "I will buy a wig; for I have art enough and knowledge of wigs to enable me to do so—as shall produce the greatest possible change in my appearance. A wig, a wig will be the thing."
Todd had hardly well made this declaration than he came upon a wig-makers, and in he went. Pointing to a wig that was on a block, and which had a very clerical kind of look, he inquired the price of it.
"Oh, my dear sir," said the wig-maker, "that is much too old looking a perriwig for you. Let me recommend you a much younger wig. Now, sir, here's one that will take a matter of ten years off your age in a moment."
Todd had discretion enough to know well that he could not make up young, so he merely pointed to the wig again, and enquired the price.
"Well, sir, it is a couple of guineas, but—"
Without another word, Todd laid down the couple of guineas, and putting the wig upon his head he left the shop, certainly having given the wigmaker an impression that he was the oddest customer he had had for some time; but
