He stopped within three feet of me. I could see his thick trousered legs through the bush. If I could get his gun.

He turned his back was towards me. I jumped him. My hands, my brain, my spring were all directed on his gun. Both my hands closed on his thick wrist and my shoulder thudded into his chest, sending him staggering. He gave a startled yelp: a blend of fury and alarm. I bent his wrist, crushed his fingers, clawed at the gun. For a split second I had it all my own way. He was paralysed by the surprise of my spring, by the pain as I squeezed his fingers against the butt of the gun. Then as I had the gun he came into action. His fist slammed into the side of my neck, a chopping blow, hard enough to drive a six-inch nail into oak. I shot into the bushes, still clinging to the gun, trying to get my finger around the trigger, but not making it before his boot kicked the gun out of my hand. It went sailing away into the scrub. Well, that was all right. If I hadn’t got it, he hadn’t either.

He came at me with a shambling rush, tearing his way through the bushes to get at me. But those sand bushes require respect. They don’t like being rushed at, and he hadn’t taken more than a couple of leaping steps before his toe stubbed against a root and he went sprawling.

That gave me time to get to my feet and leg it towards the open. If we had to fight I wasn’t going to be hampered by a lot of grass turfs, scrub and bush roots. This guy was a lot heavier than I, and had a punch like the kick of a mule, and I was still dazed from that chop on the neck. I didn’t want another. The only satisfactory way to fight him was to have plenty of space to get away and come in again.

He was up on his feet and after me in split seconds, and he could move. He caught up with me as I broke through the last screen of bushes. I dodged his first rush, socked him on the nose as he came in again and collected a bang on the side of my head that made my teeth rattle.

The moonlight fell fully on his face as he came in again: a cold, brutal, murderous mask; the face of a man who intends to kill, and nobody or nothing is going to stop him. I jumped away, wheeled back and slugged him on his squashed ear, sending him reeling, and that gave me confidence. He might be big, but he could be hit and he could be hurt. He grunted, crouched, shook his head, his hands moving forward with hooked fingers. I didn’t wait for his rush, but went in hitting with both fists. But this time his face wasn’t there, and his hands fastened on the front of my coat, pulling me against him.

I jerked up my knee, but he knew all about that kind of fighting, and had already turned sideways on, taking the hard jab of my knee against his thigh. One of his hands shifted and grabbed at my throat as I slugged him in the ribs. He grunted again, but his fingers, like steel hooks, dug into my windpipe.

Then I really went for him. I knew once he weakened me I was done for, and that paralysing grip on my throat could sap my strength in seconds if I didn’t break his hold. I hammered at his ribs, then, as he still clung on, I dug my fingers into his eyes.

He gave a sharp screech, let go of my throat and staggered back. I went after him, belting him about the body. He held his eyes and took what I handed out. There was nothing much he could do about it, and I hammered him to his knees. There was no point in breaking my fists on him, so I stepped back and waited for him to uncover. His breath came in short sobbing gasps. He tried to get to his feet, but couldn’t make it. Groaning, he dropped his hands to hoist himself up, and that was what I was waiting for. I measured him, swung a punch at him that came up from the sand and connected on the point of his jaw. He went over backwards, flopped about, scrabbling in the sand like a wounded squirrel, started climbing to his feet, fell over and straightened out.

I went over to him. He was out all right, and, looking down at the blood running out of the corners of his eyes, I felt sorry for him. I didn’t mean to hurt him as badly as that, but it was his life or mine, and at least I hadn’t killed him.
