''I believe,' said Adéle, 'that I know him.'

''Are you sure there is only one?'

''Why do you ask?' said the woman, fixing her eye upon me as though she would, in spite of every obstacle, read my inmost thoughts.

''Because I fancy there are two, for instance, Brown and Hunt.'

'At the mention of these names Adéle started to her feet, exclaiming:

''On all sides there is treachery. I demand, sir, an explanation. What leads you to associate the name of that firm with this matter? Either you are our friend or you are not. Speak plainly!'

''Madame, by the merest chance, I overheard Pedro mention those names, and since you have given me your confidence, I will give you some information which may put you on your guard, and help to guide your future plans.'

'I then briefly related the conversations I had overheard between General Valiente and Pedro, both on the Alameda and in the gaming-house in the Calle del Arco.

''Now, madame,' I continued, 'let me inquire whether the Mexican from whom you derived your information, had any connection with this firm?'

''Yes, sir, he knew them,' she replied; then, after a slight pause, she added: 'We have already told you so much that it would be folly to conceal the way in which we became acquainted with the existence of this mine. Soon after my marriage, I met a veteran officer of the Mexican army, General Ramiro, then living in exile, at New-Orleans. For me he conceived a paternal affection, and many a time remonstrated with Mr. Percival, and entreated him to devote himself to his family, and abandon the course of life which was leading him to ruin. He often spoke of his desire to return to Mexico, and lived constantly in the hope of the decree being revoked, which had driven him into exile. One day he disclosed the chief cause of his desire to return, by revealing the secret we have imparted to you.'
