The entire adventure now wore quite another aspect in her imagination. The old man and the boy were probably thieves who prowled about to pursue their avocation where they could: she had most likely been mistaken in the idea that they had entered a hackney-coach in Southampton Row simultaneously with herself; but they had followed her vehicle on foot; and when she stepped out to post her letter, the lad had taken that opportunity of creeping close up to her to pick her pocket. Having failed by the suddenness with which she had turned round, he had afterwards got up behind the coach to dog her to the end of her journey, with the hope of still succeeding in his predatory design; but when she had looked through the back-window, he had disappeared. Such was the explanation which she now arranged in her mind for her own satisfaction. But, then, what could mean the words uttered at the door of the shop in Southampton Row—"There she is, by heaven!" Fancy again came to her aid to set this point at rest:—she had most probably been watched by the old man and the lad before she was aware of the fact; and they had lost sight of her; but when they passed the shop her presence there had elicited the ejaculation from the youth. Such was the manner in which Esther tranquillised herself relative to the little occurrence that had so much alarmed her:—whether her conjectures were well-founded, or not, the reader may judge by what we are about to relate. No sooner had she posted her letter in Holborn, than Jacob, who had managed to get sight of its superscription, darted back to the second hackney-coach which had stopped near the top of Fetter Lane, and leaping in, said to Old Death, who was inside, "The letter is addressed to '_T. R., No. 5, Brandon Street, Lock's Fields_.'" "And that is Tom Rain's place," ejaculated Bones. "Well—do you follow her—get up behind the coach—and meet me at Bunce's presently." Away started Jacob; and when he was gone, Old Death alighted from the vehicle which he had hired in Southampton Row to follow Esther, dismissed it, and walked boldly into the shop where that young lady had posted her letter. A lad was in attendance behind the counter. "My boy," said Old Death, in as pleasant a tone as he could assume, "I just this minute dropped a letter into the box; and I remember that I have made a mistake in a particular circumstance mentioned in its contents." "You can't have it back again," replied the boy. "It's against the rules." "Well, I know it is," said Old Death coaxingly. "But it's of the greatest consequence to me to alter a particular part of it; and, if you'll oblige me, here's half-a-crown for your trouble." Thus speaking, he displayed the proffered coin.
