‘No shooting, I want this guy alive,’ said Harper. ‘He’s useless to us dead. We need to catch him.’

They were all suited and booted and ready to roll, they just had to see him do something.

A large figure opened the driver’s door. He went round to the back of the truck. He was wearing a coat and hat.

‘Is it Redtop?’ asked Shelton.

Harper looked, but wasn’t a hundred per cent certain. ‘Can’t be sure.’

‘No one move until he’s away from the truck. We don’t want any car chases.’

The figure stood by the back tyre and leaned into the truck. He pulled out two canisters and took them into the field. Then he returned to the truck. He manhandled a heavy rolled-up sheet with what could be a body inside. He slung the roll over his shoulder and made towards the field.

At the fence he threw the roll over and then climbed across himself. He picked it up again with some difficulty and walked toward the barn.

‘Okay, guys, you know the routine. Let’s take this guy out. Go, go, go!’

They danced out of the hides and down the hillside, running at full speed, flashlights flickering across the ground. All three pairs descended from different directions towards the single figure in the field.

The figure stopped and turned. He saw the dancing lights coming at him from all directions. He dropped the roll, picked up the canisters and ran as fast as he could towards the barn. He was big, but quick when it mattered.

Mo entered the barn and shut and locked the door. Inside, his heavy frame gulped for air. He felt the terror gripping him. He was being chased down. Like an animal. The men chasing him had just entered the field. Mo looked around. What should he do? What could he do? There were hundreds of hogs in the barn, enormous animals, sitting lazily and snorting. Maurice ran to the feed store and office at the back. He smashed open the lock and looked inside. Nothing, nothing. He looked around at the two cans of gasoline. Nick wanted him to burn the body, but he couldn’t do that now. He had to escape. But how? Mo looked at the back wall of the barn. If he could burn his way out he might be able to run and hide in the woods. Mo took a can of gasoline and started to splash it all over the back wall. Then he took the matches Nick had given him and struck one. He heard the men shouting in the fields and he dropped the match. The vapours of the gasoline ignited with a loud whoosh. And Mo was surrounded by flames.

At the edge of the field the Feds were heading for the barn. One of them stopped at the roll and had a look at what was inside it. It was the body of a woman. This was their man and they had him cornered.

This was as near as they had ever been to catching someone who might be connected to the American Devil. The Feds went on. Eddie and Harper headed round the side of the barn. Eddie pulled his handgun out as he rounded the corner, fumbled and dropped it in the mud. ‘Goddamn shit!’ he said.

As the FBI special agents arrived at the barn door, they could see the glow inside. They couldn’t quite make it out, but it was flickering like a fire.

‘He’s going to burn the barn down,’ one agent called. ‘What’s he up to?’

Then they began to hear a noise. It was a terrifying sound, rising in a crescendo of high-pitched squeals. Something was happening inside. Hundreds of pigs began to panic and move around. Inside Mo was beating at the flames but he was just throwing up sparks, and lighting the straw all over the barn.

The Feds tried smashing the lock on the barn door but it was useless, and they finally opened the lock with two rounds. The shots just frightened the pigs even more. The Feds dragged the door wide open and smelled the stink of burning gasoline and straw. As the door pulled along its steel runners, the volume of the squealing rose and hit them - a terrible, high-pitched cry of pain and fear. They looked up and saw hundred of hogs, covered in flaming gasoline, stampeding towards them.

The hogs bolted, their wide white backs alight and glowing in red and blue and amber. The smell was rich with burning flesh and the stampede was brutal as the pigs trampled and herded their way out, running directly at the two Federal agents, who had skittered backwards and somehow tripped, and were now cowering in the mud at the side of the barn. Hundreds of flaming, panicking pigs brushed past them, virtually trampling their bodies into the mud.

The blazing hogs stampeded from the barn. They sparkled across the field like a howling, terrifying light show. Within seconds they were beyond the barn and bucking and kicking in every direction, screaming out their pain and horror in high mournful squeals as their flesh melted. The special agents, miraculously alive, began crawling away from the barn.

Garcia and Mason further back, tantalizingly near the fence, were not as lucky. Mason was hit from the side full-on by a huge sow travelling at speed and then several fiery pigs ran across him, jumping and cracking his ribs and then his head. He was dragged across the field, his clothes burning against his skin.

Eddie Kasper launched himself across the ground and sprinted towards Mason’s flaming body. It was hard keeping up his speed in the mud but he was just about quick enough and rolled Mason over and over in the mud, his face badly burnt.

Garcia was tossed by a headlong charge and his clothes caught the flaming gasoline as he passed over the pigs’ backs. He landed not too badly and stood in the darkness, flapping wildly at his clothes with his hands. Harper got to him in time and managed to get his coat off and wrap it around Garcia’s body. It saved his life.

Harper looked back at the barn, swiftly realizing that the stampede meant one thing. Maurice was still in there.

‘Eddie, look after these guys, call back-up. I’ve got to get this guy.’

Eddie nodded. Harper raced around the back of the barn and spotted Maurice running away towards the edge of the field. He was slow, though, and Harper knew he was faster.

He gave chase. He knew from the map that after the field were woods, which went on for miles all the way to the river. He didn’t want Mo to reach them, but he couldn’t take a shot at him either. They needed this guy alive.

In the forest it was hard. Harper couldn’t see and had to keep stopping to listen. There was no way to track Mo otherwise. He ran, stopped and listened, blindly following Mo’s lead.

Redtop was getting ahead now. Harper kept on. It was so dark in those deep pine woods, he couldn’t see more than five feet ahead.

He followed Mo for half an hour, getting no nearer but feeling his strength drain away. Then, through the trees, he saw the flames of the pig field again. They must have come full circle, either by accident or design. Maybe Mo had no idea where to go either, so was heading back to his van. Harper found the last of his strength and began closing in again as they re-entered the field.

In the gathering light of dawn Mo knew he couldn’t make it to the truck. He didn’t dare get caught, so he ran to one of the holding ponds and climbed up the side. He stopped at the top. The venomous vapours of the shit-pit were caustic in his nose and throat. He felt immediately dizzy. Harper approached slowly, his pistol by his side.

‘Maurice, give yourself up,’ he panted. ‘There’s nowhere to go.’ Mo turned, breathing heavily. He stared at Harper, who took another few steps forward. ‘Come on, we can help you. We can look after you. Don’t kill yourself. Come down.’

‘I didn’t do nothing. I didn’t hurt them. I promise. I just looked after them. I didn’t ever hurt them.’

‘I’m sure you didn’t, Maurice, but what happened to Lottie?’

Mo looked round. He didn’t know what to say. ‘Tell him I’m sorry.’

‘Who? Tell who, Mo?’

‘I was supposed to give her water. I liked her a lot. I get to like them a lot.’
