I stood there with my mouth open, looking at Smale without seeing him, and trying hard to think fast. I hadn't been too startled when the Marines showed up; I had gone over the legal aspects of my situation months before, with a platoon of high-priced legal talent; I knew that sooner or later somebody would come around to hit me for tax evasion, draft dodging, or overtime parking; but I was in the clear. The government might resent my knowing a lot of things it didn't, but no one could ever prove I'd swiped them from Uncle Sam. In the end, they'd have to let me go—and my account in a Swiss bank would last me, even if they managed to suppress any new developments from my fabulous lab. In a way, I was glad the showdown had come.

But I'd forgotten about the Russians. Naturally, they'd be interested, and their spies were at least as good as the intrepid agents of the US Secret Service. I should have realized that sooner or later, they'd pay a call—and the legal niceties wouldn't slow them down. They'd slap me into a brain laundry, and sweat every last secret out of me as casually as I'd squeeze a lemon.

The sub was fully surfaced now, and I was looking down the barrels of half a dozen five-inch rifles, any one of which could blast Smale's navy out of the water with one salvo. There were a couple of hundred men, I estimated, putting landing boats over the side and spilling into them. Down on the lawn, the sergeant was snapping orders, and the men were double-timing off to positions that must have been spotted in advance. It looked like the Russians weren't entirely unexpected. This was a game the big boys were playing, and I was just a pawn, caught in the middle. My rosy picture of me confounding the bureaucrats was fading fast. My island was about to become a battlefield, and whichever way it turned out, I'd be the loser. I had one slim possibility; to get lost in the shuffle.

Smale grabbed my arm. "Don't stand there, man!" he snapped. "Which way—"

"Sorry, General," I said, and slammed a hard right to his stomach. He folded, but still managed to lunge for me. I gave him a left to the jaw, and he dropped. I jumped over him, plunged through the French doors, and took the spiral glass stairway four at a time, whirled, and slammed the strong-room door behind me. The armored walls would stand anything short of a direct hit with a good-sized artillery shell, and the boys down below were unlikely to use any heavy stuff for fear of damaging the goods they'd been sent out to collect. I was safe for a little while.

Now I had to do some fast, accurate thinking. I couldn't carry much with me—when and if I made it off the island. A few briefing rods, maybe; what was left of the movies. But I had already audited most of the rods; I knew them as well as I know my tax bracket. One listen to a rod gave you a fast picture of the subject; two or three repeats engraved it on your brain. The only reason a man couldn't know everything was that too much, too fast, would overload the mind—and amnesia wiped the slate clean.

I didn't have time to use any more rods, and I couldn't carry anything. But just to walk off and leave it all....

I rummaged through odds and ends, stuffing small items into my pockets. I came across a dull silvery cylinder, three inches long, striped in black and gold—a memory-trace. It reminded me of something....

That was an idea. I still had the U-shaped plastic headpiece that Foster had used to acquire a background knowledge of his old home. I had tried it once—for a moment. It had given me a headache in two seconds flat, just pressed against my temple. It had been lying here ever since. But maybe now was the time to try it again. Half the items I had here in my strong-room were mysteries, like the silver cylinder in my hand, but I knew exactly what the plastic headband could give me. It contained all anyone needed to know about Vallon and the Two Worlds, and all the marvels they possessed.

I glanced out the armor-glass window. Smale's Marines were trotting across the lawn; the Russians were fanning out along the water's edge. It looked like business all right. Still, it would take them a while to get warmed up—and more time still to decide to blast me out of my fort. It had taken an hour or so for Foster to soak up the briefing; maybe I wouldn't be much longer at it.
