"Modest? No," said the other calmly. "Modesty never got anybody anything but praise, and I prefer something more substantial. However, I never exaggerate or make over-statements, as you should know. What I have said is merely a statement of fact. Also, let me remind you that I am in a hurry. The difficulty of getting hold of that solution is growing greater every minute, and my price is getting higher every second." "What is your price at the present second?" "Ten thousand dollars per month during the experimental work; five million dollars in cash upon the successful operation of the first power unit, which shall be of not less than ten thousand horsepower; and ten percent of the profits." "Oh, come, Doctor, let's be reasonable. You can't mean any such figures as those." "I never say anything I don't mean. I have done a lot of dirty work with you people before, and never got much of anything out of it. You were always too strong for me; that is, I couldn't force you without exposing my own crookedness, but now I've got you right where I want you. That's my price; take it or leave it. If you don't take it now, the first two of those figures will be doubled when you do come to me. I won't go to anybody else, though others would be glad to get it on my terms, because I have a reputation to maintain and you are the only ones who know that I am crooked. I know that my reputation is safe as long as I work with you, because I know enough about you to send all you big fellows, clear down to Perkins, away for life. I also know that that knowledge will not shorten my days, as I am too valuable a man for you to kill, as you did...." "Please, Doctor, don't use such language...." "Why not?" interrupted DuQuesne, in his cold, level voice. "It's all true. What do a few lives amount to, as long as they're not yours and mine? As I said, I can trust you, more or less. You can trust me, because you know that I can't send you up without going with you. Therefore, I am going to let you go ahead without me as far as you can--it won't be far. Do you want me to come in now or later?" "I'm afraid we can't do business on any such terms as that," said Brookings, shaking his head. "We can undoubtedly buy the power rights from Seaton for what you ask." "You don't fool me for a second, Brookings. Go ahead and steal the solution, but take my advice and give your chemist only a little of it. A very little of that stuff will go a long way, and you will want to have some left when you have to call me in. Make him experiment with extremely small quantities. I would suggest that he work in the woods at least a hundred miles from his nearest neighbor, though it matters nothing to me how many people you kill. That's the only pointer I will give you--I'm giving it merely to keep you from blowing up the whole country," he concluded with a grim smile. "Good-bye." * * * * *
