However, he had managed through his daughter Azelma, whom he put on the track of the married couple on February 16, and by his own researches, to learn a good many things, and in his dark den had succeeded in seizing more than one mysterious thread. He had by sheer industry discovered, or at least by the inductive process had divined, who the man was whom he had met on a certain day in the Great Sewer. From the man he had easily arrived at the name, and he knew that Madame la Baronne Pontmercy was Cosette. But on that point he intended to be discreet. Who Cosette was he did not know exactly himself. He certainly got a glimpse of some bastardism, and Fantine's story had always appeared to him doubtful. But what was the good of speaking,--to have his silence paid? He had, or fancied he had, something better to sell than that; and according to all expectation, to go and make to Baron Pontmercy, without further proof, the revelation, "Your wife is only a bastard," would only have succeeded in attracting the husbands boot to the broadest part of his person. In Thénardier's thoughts the conversation with Marius had not yet begun; he had been obliged to fall back, modify his strategy, leave a position, and make a change of front; but nothing essential was as yet compromised, and he had five hundred francs in his pocket. Moreover, he had something decisive to tell, and he felt himself strong even against this Baron Pontmercy, who was so well-informed and so well-armed. For men of Thénardier's nature every dialogue is a combat, and what was his situation in the one which was about to begin? He did not know to whom he was speaking, but he knew of what he was speaking. He rapidly made this mental review of his forces, and after saying, "I am Thénardier," waited. Marius was in deep thought; he at length held Thénardier, and the man whom he had so eagerly desired to find again was before him. He would be able at last to honor Colonel Pontmercy's recommendation. It humiliated him that this hero owed anything to this bandit, and that the bill of exchange drawn by his father from the tomb upon him, Marius, had remained up to this day protested. It seemed to him, too, in the complex state of his mind as regarded Thénardier, that he was bound to avenge the Colonel for the misfortune of having been saved by such a villain. But, however this might be, he was satisfied; he was at length going to free the Colonel's shadow from this unworthy creditor, and felt as if he were releasing his fathers memory from a debtor's prison. By the side of this duty he had another, clearing up if possible the source of Cosette's fortune. The opportunity appeared to present itself, for Thénardier probably knew something, and it might be useful to see to the bottom of this man; so he began with that. Thénardier put away the "no counterfeit" carefully in his pocket, and looked at Marius with almost tender gentleness. Marius was the first to break the silence.
