Consequently, the passageway appeared darker than ever, but from my previous visits, I could visualize the location of every obstruction on the floor, and I easily stepped silently around them. I pressed my eyes up against the gaps between the door slats and looked out once more into the stable yard beyond.

There was plenty of light from the still-maneuvering car for me to see clearly. Jackson Warren was standing in the center of the yard, talking with Peter Garraway. They were each holding a shotgun in a manner that suggested that they both knew how to use them. What was it that Isabella had said? "The Garraways always come over for the end of the pheasant-shooting season-Peter is a great shot."

I think I'd have rather not known that, not right now.

As I could see Warren and Garraway in the stable yard, it must be Alex Reece who was driving the car.

"You go round the back," Jackson was saying to Garraway."Flush him out. I'll stay here in case he comes through."

I could tell from his body language that Peter Garraway really didn't like taking orders. I also suspected that he didn't much fancy "going round the back" either, good shot or not. "Why don't I wait here and you go round the back?" he replied.

"Oh, for God's sake," said Jackson, clearly annoyed. "All right. But keep your eyes fixed on that door and, if he appears, shoot him. But try to hit him in the legs."

That was slightly encouraging, I thought, but the notion of being captured alive was not. I had already experienced their brand of hospitality in these stables, and I had no desire to do so again.

Jackson Warren walked off towards the car, leaving a nervous-looking Peter Garraway standing alone in the stable yard.

Yet another Sun Tzu quote floated into my head. "In war, the way is to avoid what is strong and to strike at what is weak."

Peter Garraway was weak. I could tell by the way he kept looking towards the car and in the direction that Jackson had gone in the hope of being relieved, rather than towards the door to the passageway, as he'd been told. He obviously didn't like being left there alone. And shooting pheasants was one thing, but shooting a person would be quite another matter.

Reece had finally managed to get the car around behind the stables, and I could see the glow of its lights at the back end of the passageway. That was not good, I thought, as my position was becoming outflanked and I would soon find myself liable to attack from opposite directions.

I looked at my watch. It was only five-seventeen. Just twelve minutes had elapsed since Ian had sounded the car horn, but it felt like so much longer, and there would still be another hour of darkness.

I took another quick glimpse through the slats at Peter Garraway in the stable yard. He was resting his double-barreled shotgun in the crook of his right arm, as someone might do while waiting for the beaters to drive pheasants into the air from a game crop. It was not the way a soldier would hold a weapon-and it was not ready for immediate action.

I threw open the passageway door and ran right at him with my sword held straight out in front of me, the point aimed directly at his face, like a cavalry officer but without the horse.

He was quite quick in raising his gun but nowhere near quick enough. I was on him so fast, and as he swung the barrels up, I struck his right arm, the point of my sword tearing through both his coat and the flesh beneath. In the same motion, I hit him full on the nose with the sword's nickel-plated hand guard. He immediately went sprawling straight down onto the concrete floor, dropping the gun and clutching at his bleeding face with both hands.

I stood over him with my sword raised high, like a matador about to deliver the coup de grace. Garraway, meanwhile, curled himself into a ball with his arms up around his head, whimpering and shaking like a scolded puppy.

I aimed at his heart, and my arm began to fall.

"What are you doing?" I suddenly asked myself out loud, stopping the rapidly descending blade when it was just inches from his chest.

Values and Standards of the British Army, paragraph sixteen, states that soldiers must treat all human beings with respect, especially the victims of conflict, such as the dead, the wounded, prisoners and civilians. All soldiers must act within the law. "Soldiering," it says, "is about duty: so soldiers should be ready to uphold the rights of others before claiming their own."

Killing Peter Garraway like this would certainly not be within the law, and would definitely be a breach of his rights as my unarmed and wounded prisoner. I would simply be taking revenge for the pain and suffering that he had inflicted on me.

I noticed that he had peed himself, just as I had done the previous week in the stable, although, in my case, it hadn't been from fear. Maybe that would have to be revenge enough. I leaned down, picked up his shotgun and left him where he was, holding his face and arm, and quivering like a jelly.

I went quickly across the yard and out towards the house with the gun in one hand and my sword in the other. But the sword had now outlived its usefulness. I tossed it into the shadows at the end of the stable building and put both my hands on the gun-that was better.

I had no real plan in mind, but I knew that somehow I had to draw Jackson Warren towards me and away from my mother.

I broke open the shotgun. There was a live cartridge in each of the two chambers, but I cursed myself for not having looked for more in Peter Garraway's pockets. I could hear him behind me, calling out pitifully for Jackson, so I reckoned it was too late to go back and find them now.

So I had only two shots. I would need to make both of them count. I closed the gun once more and pushed the safety catch to off.

If I wanted to draw Jackson and Alex away from my mother, I would have to reveal my position, something that was utterly alien to any infantryman.

The headlights were still shining brightly down the back of the stables towards the muck heap, but I wasn't there anymore. I was about forty yards away, where the driveway met the turning circle near the house. I could see the car clearly from where I stood; at least I could see the headlights but from side-on.

How could I attract attention to myself?

I lifted the shotgun to my shoulder and fired one of my precious cartridges at the car. At this range the shot wouldn't penetrate the vehicle's skin, although it might just break a window. However, one thing was for sure, Alex Reece in the car would certainly know all about it.

I could hear Jackson shouting. Perhaps he had been too close to the shot for comfort. But did I care? Now they would know exactly where I was, and the car was already turning my way.

I purposely lingered a moment too long, just long enough, in fact, for the headlight beams to fall on my departing back. I weaved in the light for a split second before diving once more into the darkness down the side of the house. A shot rang out, but I was already safely protected around the corner.

I moved swiftly, grateful that I had made an extensive reconnaissance here the previous Thursday. I knew that the concrete path alongside the exterior walls ran completely around the rectangular building, the only obstacle being a small gate at one of the back corners.

In no time, I had completed the circuit and approached the front of the house again, but now I was behind the car, its headlamps still blazing towards where I had been just seconds before. In the glow I could see Jackson creeping forwards towards the corner, his gun raised to his shoulder, ready to fire.

The driver's door of the car suddenly opened, and Alex stood up next to the vehicle, facing away from me, watching Jackson intently.
