For the first time during the interview Arthur awoke from his pre-occupation, and glanced keenly at Dumphy. "Of course," he returned, coolly, "I don't suppose you such a fool as to allow the only witness you have of your wife's death to be sacrificed--even if you believed that the impostor who was personating your wife had been charged with complicity in a capital crime and had fled from justice. You're not such a fool as to believe that this Mrs. Conroy won't try to help her husband, that she evidently loves, by every means in her power--that she won't make use of any secret she may have that concerns you to save him and herself. No, Mr. Peter Dumphy," said Arthur significantly; "no, you're too much of a business man not to see that." As he spoke he noted the alternate flushing and paling of Mr. Dumphy's face, and read--I fear with the triumphant and instinctive consciousness of a superior intellect--that Mr. Dumphy _had_ been precisely such a fool, and had failed! "I reckon nobody will put much reliance on the evidence of a woman charged with a capital crime," said Mr. Dumphy, with a show of confidence he was far from feeling. "Suppose that she and Gabriel both swear that _she_ knows your abandoned wife, for instance; suppose that they both swear that she and you connived to personate Grace Conroy for the sake of getting the title to this mine; suppose that she alleges that she repented and married Gabriel, as she did, and suppose that they both admit the killing of this Ramirez--and assert that you were persecuting them through him, and still are; suppose that they show that he forged a second grant to the mine--through _your_ instigation?" "It's a lie," interrupted Dumphy, starting to his feet; "he did it from jealousy." "Can you _prove_ his motives?" said Arthur. "But the grant was not in my favour--it was to some old Californian down in the Mission of San Antonio. I can prove that," said Dumphy, excitedly. "Suppose you can? Nobody imagines you so indiscreet as to have had another grant conveyed to _you directly_, while you were negotiating with Gabriel for _his_. Don't be foolish! _I_ know you had nothing to do with the forged grant. I am only suggesting how you have laid yourself open to the charges of a woman of whom you are likely to make an enemy, and might have made an ally. If you calculate to revenge Ramirez, consider first if you care to have it proved that he was a confidential agent of yours--as they will, if you don't help _them_. Never mind whether they committed the murder. You are not their judge or accuser. You must help them for your own sake. No!" continued Arthur, after a pause, "congratulate yourself that the Vigilance Committee did not hang Gabriel Conroy, and that you have not to add revenge to the other motives of a desperate and scheming woman." "But are you satisfied that Mrs. Conroy _is_ really the person who stands behind Colonel Starbottle and personates my wife?" "I am," replied Arthur, positively.
