shadows across the slabs. It wouldn't be long now before someone in Mallon's task force spotted me and opened up with the guns— 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. The slab under me trembled as if in anticipation. I squinted against the dull red IR beams that pivoted to hold me, waiting while the Troll considered. Then the guns elevated, pointed over my head like a benediction. The Bolo knew me.
