I sat for a moment taking deep breaths to drive back the compulsive drowsiness that was sliding down over my eyes like a visor. My arm throbbed like a cauterized stump. I needed a few minutes’ rest…

A sound brought me awake like an old maid smelling cigar smoke in the bedroom: the rise and fall of heavy engines in convoy. Mallon was coming up at flank speed.

I got out of the car and headed off along the road at a trot, holding my broken arm with my good one to ease the jarring pain. My chances had been as slim as a gambler’s wallet all along, but if Mallon beat me to the objective, they dropped to nothing.

The eastern sky had taken on a faint gray tinge, against which I could make out the silhouetted gateposts and the dead floodlights a hundred yards ahead.

The roar of engines was getting louder. There were other sounds, too: a few shouts, the chatter of a 9-mm, the boom! of something heavier, and once a long-drawn whoosh! of falling masonry. With his new toy, Mallon was dozing his way through the men and buildings that got in his way.

I reached the gate, picked my way over fallen wire mesh, then headed for the Primary Site.

I couldn’t run now. The broken slabs tilted crazily, in no pattern. I slipped, stumbled, but kept my feet. Behind me, headlights threw 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—
