de Morito, of Gloster, are identical; and, believing this, I consider it my duty to tell you these facts in order that your citizens may be protected against him, if possible." "Well, Mr. Pinkerton," said Judge Key, "what do you think of this affair? Mr. Warne does not admit that he can be mistaken, and there are some corroboratory evidences that he may be right; yet, it seems incredible. It is a pity that Mr. Warne should have never seen Don José's wife, because he could then compare her with Señora Morito, and if they, too, were exact resemblances, there would be no longer any room for doubt." "That would certainly be a strong proof," I remarked; "but I think it is unnecessary. The suspicion you have spoken of, Mr. Warne, has already been raised by another gentleman in this city, and I have been requested to discover whether or not it is correct." "Why, you astonish me!" exclaimed Judge Key, "for Mr. Warne has not mentioned the subject to any one but me, and I have never even hinted anything about it except to you gentlemen." "Nevertheless, I have suspected for some time that this Don Pedro was an impostor, and have been trying to obtain positive proof of my opinion, in order to save many persons here from being swindled by him. You are acquainted with Senator Muirhead, Judge?" "Oh! yes, quite well." "He has taken enough interest in the affairs of his constituents to place in my hands the task of exposing this man, Don Pedro, in his true light." "That seems very kind and disinterested on the part of our Senator," said Judge Key, with a quizzical smile; "but I will venture to say that his interest has been excited more by the Don's marked attentions to Mrs. Muirhead, than by the fear that some of his constituents would be defrauded." Of course I took no notice of this remark, although I was quite convinced that such was the fact; but as the Senator was my client, it would have been eminently improper for me to discuss his motives, and so I turned to Mr. Warne. "As you have already met this man under another name, Mr. Warne," I said, "can you not go with me to meet Senator Muirhead, and tell him what you know about him?"
