"I could see it all just as he painted it. My political career was very dear to me just then. Such a thing would have killed it. I knew if I exposed him he was capable of carrying out his threat. However, I told him to get out of the place before I threw him out of the window. He could see I was losing my temper and took a little pistol from his pocket--a Derringer. "'I have a number of letters which you sent to a lady in Vienna,' he said. 'I know many newspapers which would offer me a good price for 'em.' "I think it was perhaps fortunate for me that he held the pistol--or I might have done something I should afterwards have regretted. He flung a letter face upwards on the table. It was one of those I had written to Lola Rachael. If he had the rest of the correspondence--and he swore that he had--it would have been deadly in the hands of an unscrupulous political opponent. As you know, electioneering in the States is rather different from what it is here. I was fool enough to pay him money on his promise to suppress them. He would not sell them outright. "That was the beginning. After that I never had a secure moment unless I was away on an exploring expedition. The moment I reappeared in civilisation my brother would seek me out. He was cunning enough to press me only to the verge of endurance. He could judge exactly how much I would stand. At last, however, I resolved not to yield another penny to his extortions. I cut loose from all my affairs in the United States and came to England. I thought I could fight him when I had reduced the stakes. I found after all that I had increased them, for I met Eileen--Lady Eileen Meredith." He paused. Neither of his two hearers said anything. An injudicious remark might break the thread of his thoughts. "When I became engaged to her," Grell resumed, "I knew that it would not be long before Goldenburg would see his chance. I set to work to find Lola, and discovered her as the Princess Petrovska. Then for the first time I learned that she had married Goldenburg--but she admitted that any affection she held for him had long since faded. They had parted a few weeks after the marriage--which they both seemed to regard somewhat cynically--and she had resumed her first husband's name. She admitted that she had helped him to blackmail me, but apparently she herself had handled little enough of the loot. She was vicious enough about it. I gave her a cheque and induced her to come to London. I had it in mind to stop this blackmail before I was married.
