"His girl was running a hidden observation tower here," Pop was saying now. "Weather and all that, I suppose. Or maybe setting up a robot station of some kind. I couldn't tell you about her before, because you were both in a mood to try to rub out anybody remotely connected with the Pilot. In fact, I did my best to lead you astray, letting you think I'd been the one to scream and all. Even now, to be honest about it, I don't know if I'm doing the right thing telling and showing you all this, but a man's got to take some risks whatever he does." "Say, Pop," I said dully, "isn't she apt to take a shot at us or something?" Not that I'd have minded on my own account. "Or are you and her that good friends?" "Nope, Ray," he said, "she doesn't even know me. But I don't think she's in a position to do any shooting. You'll see why. Hey, she hasn't even shut the door. That's bad." He seemed to be referring to a kind of manhole cover standing on its edge just inside the open-walled first story of the cracking plant. He knelt and looked down the hole the cover was designed to close off. "Well, at least she didn't collapse at the bottom of the shaft," he said. "Come on, let's see what happened." And he climbed into the shaft. We followed him like zombies. At least that's how I felt. The shaft was about twenty feet deep. There were foot- and hand-holds. It got stuffy right away, and warmer, in spite of the shaft being open at the top. At the bottom there was a short horizontal passage. We had to duck to get through it. When we could straighten up we were in a large and luxurious bomb-resistant dugout, to give it a name. And it was stuffier and hotter than ever. There was a lot of scientific equipment around and several small control panels reminding me of the one in the back of the plane. Some of them, I supposed, connected with instruments, weather and otherwise, hidden up in the skeletal structure of the cracking plant. And there were signs of occupancy, a young woman's occupancy--clothes scattered around in a frivolous way, and some small objects of art, and a slightly more than life-size head in clay that I guessed the occupant must have been sculpting. I didn't give that last more than the most fleeting look, strictly unintentional to begin with, because although it wasn't finished I could tell whose head it was supposed to be--the Pilot's. * * * * * The whole place was finished in dull silver like the cabin of the plane, and likewise it instantly struck me as having a living personality, partly the Pilot's and partly someone else's--the personality of a marriage. Which wasn't a bit nice, because the whole place smelt of death. But to tell the truth I didn't give the place more than the quickest look-over, because my attention was rivetted almost at once on a long wide couch with the covers kicked off it and on the body there.
