A crude breastwork had been thrown up just over fifty yards from it. A wheel-mounted generator putted noisily in the background, laying a layer of bluish exhaust in the air.
Mallon was waiting with a 9-mm power rifle in his hands as we came up, my two guards gripping me with both hands to demonstrate their zeal, and me staggering a little more than was necessary. I saw Renada standing by, wrapped in a gray fur. Her face looked white in the harsh light. She made a move toward me and a greenback caught her arm.
"You know what to do, Jackson," Mallon said speaking loudly against the clatter of the generator. He made a curt gesture and a man stepped up and buckled a stout chain to my left ankle. Mallon held out my electropass. "I want you to walk straight to the Bolo. Go in by the side port. You've got one minute to cancel the instructions punched into the command circuit and climb back outside. If you don't show, I close a switch there-" He pointed to a wooden box mounting an open circuit-breaker, with a tangle of heavy cable leading toward the Bolo-"and you cook in your shoes. The same thing happens if I see the guns start to traverse or the antipersonnel ports open." I followed the coils of armored wire from the chain on my ankle back to the wooden box-and on to the generator.
"Crude, maybe, but it will work. And if you get any idea of letting fly a round or two at random-remember the girl will be right beside me."
I looked across at the giant machine. "Suppose it doesn't recognize me? It's been a while. Or what if Don didn't plug my identity pattern in to the recognition circuit?"
"In that case, you're no good to me anyway," Mallon said flatly.
I caught Renada's eye, gave her a wink and a smile I didn't feel, and climbed up on top of the revetment.
I looked back at Mallon. He was old and shrunken in the garish light, his smooth gray suit rumpled, his thin hair mussed, the gun held in a white-knuckled grip. He looked more like a harassed shopkeeper than a would-be world-beater.
"You must want the Bolo pretty bad to take the chance, Toby," I said. "I'll think about taking that wild shot. You sweat me out."
I flipped slack into the wire trailing my ankle, jumped down, and started across the smooth-trimmed grass, a long black shadow stalking before me. The Bolo sat silent, as big as a bank in the circle of the spotlight. I could see the flecks of rust now around the port covers, the small vines that twined up her sides from the ragged stands of weeds that marked no-man's-land.
There was something white in the brush ahead. Broken human bones.
I felt my stomach go rigid again. The last man had gotten this far; I wasn't in the clear yet…
I passed two more scattered skeletons in the next twenty feet. They must have come in on the run, guinea pigs to test the alertness of the Bolo. Or maybe they'd tried creeping up, dead slow, an inch a day; it hadn't worked…
Tiny night creatures scuttled ahead. They would be safe here in the shadow of the troll where no predator bigger than a mouse could move. I stumbled, diverted my course around a ten-foot hollow, the eroded crater of a near miss.
Now I could see the great moss-coated treads sunk a foot into the earth, the nests of field mice tucked in the spokes of the yard-high bogies. The entry hatch was above, a hairline against the great curved flank. There were rungs set in the flaring tread shield. I reached up, got a grip and hauled myself up. My chain clanked against the metal. I found the door lever, held on and pulled.
It resisted, then turned. There was the hum of a servo motor, a crackling of dead gaskets. The hairline widened and showed me a narrow companionway, green-anodized dural with black polymer treads, a bulkhead with a fire extinguisher, an embossed steel data plate that said BOLO DIVISION OF GENERAL MOTORS CORPORATION and below, in smaller type, unit, combat, BOLO MARK III.
I pulled myself inside and went up into the Christmas-tree glow of instrument lights.
The control cockpit was small, utilitarian, with two deep-padded seats set among screens, dials, levers. I sniffed the odors of oil, paint, the characteristic ether and ozone of a nuclear generator. There was a faint hum in the air from idling relay servos. The clock showed ten past four. Either it was later than I thought, or the chronometer had lost time in the last eighty years. But I had no time to lose…
I slid into the seat, flipped back the cover of the command control console. The Cancel key was the big white one. I pulled it down and let it snap back, like a clerk ringing up a sale.
A pattern of dots on the status display screen flicked out of existence. Mallon was safe from his pet troll now.
It hadn't taken me long to carry out my orders. I knew what to do next; I'd planned it all during my walk out. Now I had thirty seconds to stack the deck in my favor.
I reached down, hauled the festoon of quarter-inch armored cable up in front of me. I hit a switch, and the inner conning cover-a disk of inch-thick armor-slid back. I shoved a loop of the flexible cable up through the aperture, reversed the switch. The cover slid back-slicing the armored cable like macaroni.
I took a deep breath, and my hands went to the combat alert switch, hovered over it.
It was the smart thing to do-the easy thing. All I had to do was punch a key, and the 9-mm's would open up, scythe Mallon and his crew down like cornstalks.
But the scything would mow Renada down, along with the rest. And if I went-even without firing a shot-Mallon would keep his promise to cut that white throat…
My head was out of the noose now, but I would have to put it back-for a while.
I leaned sideways, reached back under the panel, groped for a small fuse box. My fingers were clumsy. I took a breath, tried again. The fuse dropped out in my hand. The Bolo's I-R circuit was dead now. With a few more seconds to work, I could have knocked out other circuits-but the time had run out.
I grabbed the cut ends of my lead wire, knotted them around the chain and got out fast.

Mallon waited, crouched behind the revetment.
"It's safe now, is it?" he grated. I nodded. He stood, gripping his gun.
"Now we'll try it together."
I went over the parapet, Mallon following with his gun ready. The lights followed us to the Bolo. Mallon clambered up to the open port, looked around inside, then dropped back down beside me. He looked excited now.
"That does it, Jackson! I've waited a long time for this. Now I've got all the mana there is!"
"Take a look at the cable on my ankle," I said softly. He narrowed his eyes, stepped back, gun aimed, darted a glance at the cable looped to the chain.
"I cut it, Toby. I was alone in the Bolo with the cable cut-and I didn't fire. I could have taken your toy and set up in business for myself, but I didn't."
"What's that supposed to buy you?" Mallon rasped.
"As you said-we need each other. That cut cable proves you can trust me."
Mallon smiled. It wasn't a nice smile. "Safe, were you? Come here." I walked along with him to the back of the Bolo. A heavy copper wire hung across the rear of the machine, trailing off into the grass in both directions.
"I'd have burned you at the first move. Even with the cable cut, the armored cover would have carried the full load right into the cockpit with you. But don't be nervous. I've got other jobs for you." He jabbed the gun muzzle hard into my chest, pushing me back. "Now get moving," he snarled. "And don't ever threaten the Baron again."
