"Then about all I can do is to get everything I can on that Steel crowd, and that is very much like trying to get blood out of a turnip. I intend to keep after them, of course, for I owe them something for killing two of my men here, as well as for other favors they have done me in the past, but don't expect too much. I have tackled them before, and so have police headquarters and even the Secret Service itself, under cover, and all that any of us has been able to get is an occasional small fish. We could never land the big fellows. In fact, we have never found the slightest material proof of what we are morally certain is the truth, that World Steel is back of a lot of deviltry all over the country. The little fellows who do the work either don't know anything or are afraid to tell. I'll see if I can find out what they are doing with the stuff they stole, but I'm not even sure of doing that. You can't plant instruments on that bunch—it would be like trying to stick a pin into a sleeping cat without waking him up. They undoubtedly have one of the best corps of detectives in the world. You haven't perfected an instrument which enables you to see into a closed room and hear what is going on there, have you?" And upon being assured that they had not, he took his leave.

"Optimistic cuss, ain't he?" remarked Seaton.

"He has cause to be, Dick. World Steel is a soulless corporation if there ever was one. They have the shrewdest lawyers in the country, and they get away legally with things that are flagrantly illegal, such as freezing out competitors, stealing patents, and the like. Report has it that they do not stop at arson, treason, or murder to attain their ends, but as Prescott said, they never leave any legal proof behind them."

"Well, we should fret, anyway. Of course, a monopoly is what they're after, but they can't form one because they can't possibly get the rest of our solution. Even if they should get it, we can get more. It won't be as easy as this last batch was, since the X was undoubtedly present in some particular lot of platinum in extraordinary quantities, but now that I know exactly what to look for, I can find more. So they can't get their monopoly unless they kill us off...."

"Exactly. Go on, I see you are getting the idea. If we should both conveniently die, they could get the solution from the company, and have the monopoly, since no one else can handle it."

"But they couldn't get away with it, Mart—never in a thousand years, even if they wanted to. Of course I am small fry, but you are too big a man for even Steel to do away with. It can't be done."

"I am not so sure of that. Airplane accidents are numerous, and I am an aviator. Also, has it ever occurred to you that the heavy forging for the Skylark, ordered a while ago, are of steel?"

Seaton paused, dumbfounded, in the act of lighting his pipe.

"But thanks to your object-compass, we are warned." Crane continued, evenly. "Those forgings are going through the most complete set of tests known to the industry, and if they go into the Skylark at all it will be after I am thoroughly convinced that they will not give way on our first trip into space. But we can do nothing until the steel arrives, and with the guard Prescott has here now we are safe enough. Luckily, the enemy knows nothing of the object-compass or the X-plosive, and we must keep them in ignorance. Hereinafter, not even the guards get a look at anything we do."

"They sure don't. Let's get busy!"
