'I have no farther news, and there are no farther complications that I know of,' replied Carey, 'and my paleness is probably occasioned by the fact of my having laid awake nearly all night thinking over those which already existed. That woman's confession yesterday, and the information which we received from the perusal of Mrs. Griswold's diary, prove to me incontestably that Helen is right in fixing the suspicion of her husband's murder on Warren by supplying the motive for his crime.' 'I am entirely of your opinion,' said Bryan. 'The scoundrel had made love to Mrs. Griswold, and, afraid that she would communicate his baseness to her husband on his return, made away with him; the incident is not at all unnatural, or rather I should say is perfectly dramatic. I have used it more than once in the course of my career, and never knew it fail to bring down the house.' 'I guess we shall find that he was influenced by other motives as well,' said Carey. 'After I left you last night, I went carefully through a portion of Griswold's papers, and by what I could glean from them, I have little doubt that the poor fellow has been mercilessly robbed by his trusted friend. It would be most important if we could learn fuller particulars of Griswold's method of life while in England; you have furnished us with most valuable information, but of course yours was but a casual acquaintance with him. If we could only get at some of those who were there mixed up with him in his business transactions, it might materially assist us.' 'I have been thinking of that also,' said Bryan Duval, 'and it appears to me that our first step should be to try and find out what has become of a certain Mr. Dolby, an American gentleman whom you may or may not have heard mentioned by Miss Montressor. He was in England immediately before the day of the murder, but I think spoke of returning to America very soon.' 'There would be no difficulty in ascertaining his whereabouts, I should imagine,' said Carey, 'from Miss Montressor herself.' 'Well,' said Bryan Duval, speaking slowly, 'that is a matter in which we must proceed with a good deal of delicacy. There were, I imagine, certain relations between Mr. Dolby and our dear friend Clara which you, in your virtuous and secluded life, my dear sir, probably know very little about, which nevertheless do exist in this wicked world, and, so far as my experience goes, have great weight in the conduct of its affairs. This being the case, in conversation with Miss Montressor we must handle the subject very gingerly; for Clara, though a flirt and a coquette, is thoroughly staunch and loyal, and nothing could induce her to betray her friend.' 'To betray him?' said Carey.
