He'd finished vomiting but the air was putrid and I moved away a little, observing him. His face was bloodless under the dirt, his eyes closed; his breathing was steady but faint, his chest hardly moving. The assault rifle was lying near him, but not near enough for him to reach it before I could if I saw him move.

He began moaning now and I hated that: a scream I can handle because it's simply the sound of shock, but a moan is a plea for help and I couldn't help him.

He's one of the people who blows the legs off little children.

Well said, and timely.

Think, keep thinking. How long would it be before they came out here to see why these two hadn't returned, performed the execution and returned?

Not long.

I crawled towards the man and lay close to him, put my mouth to his ear.

'What will happen on the nineteenth?'

He didn't answer.

There would be a case, there would be a case here of inflicting further pain on him, if I thought it would impress him, persuade him to answer me, and it would have been acceptable for me to do that, to further traumatize this blower-of-the-legs-off-little-children; but it wouldn't physically be possible: pain was already roaring in him, and there was nothing I could add that he would feel.

Fear, then, of death? I felt for his throat. 'What will happen on the nineteenth?'

It would be nice to have something to debrief to Pringle, Flockhart, something perhaps conclusive: a Pol Pot attack on the capital, an assassination attempt on the king, something I could call information, which was what I was here for, putting more pressure on this man's windpipe, letting him think of death, using both thumbs and working inward — and then he moved and I was fighting off a claw-hand strike to the eyes and going down and rolling over, blocking a fist and forcing a heel-palm to the nose and missing, feeling the slickness of blood as the skin came away, my breath coming short as he struck again and the fear of death was mine, not his, until I found purchase for my left shoulder and drove a half-fist into the larynx and felt the cartilage snap and he reeled sideways and dropped, dropped like a sack with blood creeping from the corner of his mouth.

I got up and stumbled across the stones, found my way to the nearest jeep, my own, and dragged out two bottles of Evian water and went over to the other jeep and found the key still in the ignition, here was the trick, the point of no return: I hadn't got the strength to make my way out through the mountains on foot — they'd be here soon now, wanting to know why their comrades hadn't returned.

The engine fired at once and I took the thing through the gears as quietly as I could. The Chinese-built vehicle was larger than mine, would be faster — but they'd hear it from the camp, I knew that, would think for a moment that the jeep was on its way back until they heard the sound fading — then they would react. It was simply a question of time, and I shifted into overdrive as soon as the engine could take it, pushing the speed up and switching on the headlights as the track began turning through the hills.

With one hand I tore the cap off a bottle of water and took swigs at it and then washed the dried spittle off my face, flicking my eyes across the three mirrors in turn as the track straightened and ran between boulders for half a mile and then began twisting and rising, the bottle of water empty now and the mirrors still dark, the waxing moon afloat in the southern sky and the rim of the mountains lying in waves below it, touched here and there by its reflection on flat rock.

The jeep lost traction sometimes over the loose shale, skating at an angle and coming back as I shifted gears to get control; there were something like fifteen degrees of play in the steering box and it was tricky to keep this brute from Beijing on course. I was using third gear now, because -

Lights.

In the left-hand mirror, fanning between the hills behind and below me, flashing once as they came directly in line and then fading, blacked-out suddenly by a turn in the track. They would belong to a vehicle leaving the camp: all traffic on this route was strictly Khmer Rouge.

The major road to Pouthisat was still some way ahead, two miles, two and a half, and there wasn't a single chance of driving out of this. Their lights were in the right-hand mirror now, flashing again as they lined up, brighter this time. The crew on board had already found my jeep standing there and this one gone; they might have stopped long enough to take a look around and seen the two soldiers lying there among the rocks. They would therefore be driving flat out and with purpose, and even if I got to the major road before they did I'd be within range of their guns, finito.

The terrain was steeper here, with rifts and gullies filled with shadow in the peripheral glow of my lights, and I began watching for somewhere to ditch.

There might of course be nowhere — I might simply have to stop this thing and get out and walk, run, while there was time. Question: how long would it take those people behind me to raise the alarm and bring a search party of a hundred men here in packed transports, two hundred, five?

The jeep was skating again and I shifted down and got traction. Light came suddenly and in all three mirrors this time as the track ran straight for a while. They'd closed the distance by half, by more than half: their lights were throwing shadows now from the rear window of the jeep.

Then I saw the gully leading away from the track, deeper than a gully, a small ravine, and steep, and I waited until the lights behind me were blacked-out by the rocks and then wrenched the jeep into a spin with the power still on and sent it towards the slope, dousing the headlights and hitting the brakes and jumping clear with enough momentum left in the thing to take it to the bottom of the ravine.

I was lying flat among boulders when the Khmer transport came storming past, and as soon as its lights had died away I stumbled down to the jeep. It had rolled twice, and one wheel was still turning slowly in the moonlight. I took the flashlamp out of its bracket and found the last bottle of water lying among the rocks and picked it up and took it with me as I moved higher, away from the track.

The moon was down, and in the east a pale flush of light threw the length of a mountain ridge into silhouette. Below and to the west the valley was lost beneath a veil of mist. A bird called, piping thinly in the silence.

I hadn't slept. The Khmer transport that had gone storming past the place where I had ditched the jeep had driven as far as the major road and turned north towards Pouthisat; after a while it had returned and plunged into the valley, following the track to the camp. Within thirty minutes the lights of a dozen vehicles had come swinging east towards the major road, half of them turning north and the others south to take up the hunt. It was long after midnight when I saw them again, threading their way through the valley back to the camp.

I had lain down, then, using the half-empty plastic bottle for a head-rest, listening to the silence that had now come down front the hills to rest along the valley floor. But sleep was out of my reach. Bruises from unremembered blows were throbbing now; injuries I had not been aware of were bringing pain, demanding my attention. And there were thoughts running wild in my head, disallowing peace, baying like hounds at the kill.

Later I would have to deal with them.

When the flush of light in the east became strong enough to cast shadows I finished the last of the water and left my shelter in the rocks to climb into the eye of the sun towards the road.
