The whoop! whoop! WHOOP! of the guardian Bolo cut across the field.
Across the broken concrete I saw the two red eyes flash, sweeping my way. I looked toward the gate. A massed rank of vehicles stood in a battalion front just beyond the old perimeter fence, engines idling, ranged for a hundred yards on either side of a wide gap at the gate. I looked for the high silhouette of Mallon's Bolo, and saw it far off down the avenue, picked out in red, white and green navigation lights, a jeweled dreadnaught. A glaring cyclopean eye at the top darted a blue-white cone of light ahead, swept over the waiting escort, outlined me like a set-shifter caught onstage by the rising curtain.
The whoop! whoop! sounded again; the automated sentry Bolo was bearing down on me along the dancing lane of light.
I grabbed at the plastic disk in my pocket as though holding it in my hand would somehow heighten its potency. I didn't know if the Lesser Troll was programmed to exempt me from destruction or not; and there was only one way to find out.
It wasn't too late to turn around and run for it. Mallon might shoot—or he might not. I could convince him that he needed me, that together we could grab twice as much loot. And then, when he died—
I wasn't really considering it; it was the kind of thought that flashes through a man's mind like heat lightning when time slows in the instant of crisis. It was hard to be brave with broken bone ends grating, but what I had to do didn't take courage. I was a small, soft, human grub, stepped on but still moving, caught on the harsh plain of broken concrete between the clash of chrome-steel titans. But I knew which direction to take.
The Lesser Troll rushed toward me in a roll of thunder and I went to meet it.
It stopped twenty yards from me, loomed massive as a cliff. Its heavy guns were dead. I knew. Without them it was no more dangerous than a farmer with a shotgun—
But against me a shotgun was enough.
