"Can you prove your point?"
"Yes, even to your satisfaction."
"I'm all attention," he said.
"In the first place," she began, "you must understand that Colonel Darcy and I were secretly married four years ago, in Ireland. I'll show you my marriage certificate, to prove my words, when we return to the house. I always carry it with me in case of an emergency."
Kent-Lauriston nodded, and she continued:—
"The Colonel married me under the impression that I was an heiress. I married him because I thought I loved him. We both discovered our mistakes within the first few days. No one knew of the step we had taken, so we agreed to separate. This is a practical age. As Miss Fitzgerald I'd hosts of friends; as Mrs. Darcy, a girl who had made a worse than foolish marriage, I should have had none. The Colonel had expected his wife to support him; he was in no condition to support her. His regiment was ordered to India; if he resigned, his income was gone. We decided to keep our secret. I remained Miss Fitzgerald. He went to India. Three years later he was invalided home. Travelling for his health, he returned by way of South America. There he met Inez De Costa, and won her love. She combined the two things he most craved, position and wealth. He had heard nothing from me for many months. He allowed his inclinations to guide his reason, and, trusting that I was dead, or had done something foolish, he married her and returned to England. We met. My natural impulse was to denounce him, but sober second thought showed the futility of such a course. I'd nothing to gain; everything to lose. He sent me money. I returned it. Do you believe that?"
"I believe you implicitly," replied Kent-Lauriston.
"Then he came to see me; for I think he still loved me. He came, I say, fearfully at first, lest I should betray him. Then growing bolder, he threw off all reserve. Believing, fool that he was, because I didn't denounce him, that I could ever forget or forgive the wrong he'd done me. He mistook compliance for forgetfulness, even had the audacity to suggest that I, too, should marry.
"Then this scheme for defeating the treaty was proposed to him. He was willing enough to undertake it, for his second matrimonial venture had been a pecuniary failure, thanks to the wisdom of Señor De Costa in tying up his daughter's property; but he lacked the brains to carry it out, and, like the fool that he is, came to me for assistance. I had lulled his suspicions, and he needed a confederate. He even held out vague promises of a future for us both, as if I'd believe his attested oath, after what had passed! I consented to help him, and would have brought the matter to a successful issue, if it hadn't been for his stupidity. What did I care about the success or failure of his plot? It had put the man in my power, put him where I wanted to have him. At any time within the last six weeks I could have forced him to publicly recognise me, if need were."
"What prevented you from doing this?"
