Tim Lebbon - London Eye

One grave , Lucy-Anne thought, and a flash of memory stabbed at her again. Again, she drove it away.

“Dead London,” Sparky said. “Bloody freaking me out, I know that for sure.”

“There are some rough paths to follow. We'll be across in a few minutes.” Rosemary looked nervously back the way they had come, where the sun was just disappearing below a line of rooftops.

Her nervousness unsettled Lucy-Anne even more. She can't really mean it's haunted? She looked around at the grotesque, strange surroundings, and the silence that enclosed them felt like a held breath. What sounds the Barrens would utter once darkness fell, she had no wish to discover.

They passed more memorials of all shapes, sizes, and designs. One was constructed in cast concrete, eight feet tall and six wide, and three names were carved lovingly into its surface. Another was a brick-built square thirty feet across, the ground within flattened and planted as a perfect lawn, a small wooden cross at its centre. Whoever had built it obviously maintained it, as the grass was trimmed and the cuttings strewn beyond the wall. There were countless wooden markers; many crosses, and others simply stakes driven into the ground. Pictures were pinned to some of them, the majority faded and leached of colour by the sun, but some obviously replaced frequently. Others had names carved into them. As well as the brick or stone markers, there were other elaborate sculptures of twisted and shaped metal that would not have looked out of place in an art gallery.

They could be here , Lucy-Anne thought. Every step she took was painful, and the silence from the rest of the group testified to their upset as well. Among them all, Jack and Emily were the lucky ones. They had family, and everyone else walked alone.

“Oh,” Rosemary said. She paused, glanced back and then continued walking. Perhaps the sun was sinking too quickly for her to think about changing their course.

Someone or something had excavated a hole thirty feet from the rough path they were following. Soil and broken masonry had been dug through to reach the softer parts beneath, and in the dusky light the spread of bones looked pink. There were skulls in there, and leathery skin, and hair twisted across stretched features.

Lucy-Anne fell to her knees. Something about this place was so familiar, and yet her memory teased her still. Just do it! she thought, challenging her nightmares to strike her once again. But if they did have something to say about this place, they held back.

For the next couple of minutes they had to step over and around a mess of bones splayed across the path. Some of them bore teeth marks. Others had been chewed through to get to the good stuff inside.

Rosemary led them on, and as daylight fled and gave the Toxic City back to the night, they left that sad, surreal place and found themselves once more in familiar streets.

They gathered in a small square where once-tended plants had grown wild, and where birds chattered as they chose their roosts for the night.

“It's not far now,” Rosemary said. “There's a house two streets away that I sometimes use. There's food there, and bottled water, and enough rooms-”

“Listen!” Sparky held up his hand, eyes wide, head tilted to one side. The birds had also fallen silent, equally attuned to the sound of danger. “Engines.”

“Quickly!” Rosemary led them across the road and through a gate into the small park at the square's centre. “Hide, stay low, and whatever you do, make sure you're not seen.”

“Choppers?” Jenna asked.

“Almost certainly. Irregulars hardly ever use vehicles.”

Lucy-Anne hid with Jack and Emily behind a bank of undergrowth growing around an old oak tree. She looked for the others but they had all hidden themselves away so well that even she could no longer see them. She had the crazy idea that they had never been there at all.

“I'm afraid,” Emily said.

The motors were drawing closer. There were several of them, and above their grumble he heard the distinctive sound of something else: a helicopter.

“Me too.” Lucy-Anne smiled at the girl.

“But we're here,” Jack whispered into his sister's ear. “We're in London, and Mum and Dad will be here too.”

“Yeah,” she said, smiling. “Do you think they'll remember us?”

Jack tried to answer, but his voice broke. “Shh,” he said instead. He glanced at Lucy-Anne and she saw tears in his eyes. “Shh.”

The helicopter passed overhead. She saw it through the jagged branches of the oak tree, its tail light flashing red as it hovered briefly, then thundered away across the Barrens. It was too high for its downwash to be felt, but so loud that Lucy-Anne could not even hear her own breathing. She noticed that though Emily cringed into her brother, her right hand was held out from her side, the dark lens of the camera facing up.

As the helicopter drifted away, the square was illuminated by a flood of headlamps. Lucy-Anne tried to hunker down lower, gasping as the light fingered through bushes and between tree trunks to briefly dazzle her. The engine sound did not change. She heard heavy wheels grinding on the gritty road, and another set of headlamps swung through to follow the first. The two vehicles grumbled around the square, their engine noise intensely threatening. But behind them, a heavier sound. It rumbled and shook through the ground as well as through the air, and it made leaves in the square shake where the helicopter could not.

“What's that?” Emily asked.

“Don't know. Big truck.” Lucy-Anne peered through the bushes, trying to make out the shape and size of the two vehicles driving around the edge of the square. They seemed quite small, but before she could get a good look, they were gone, and the massive rumble that followed them took over.

It echoed from the buildings around the square, shook the ground, and the lights-red, yellow, and white-slashed through the undergrowth as if it was not there. It ended the shadows in that place, and its motor sounded angry and hungry.

The vehicle turned around the edge of the square, following the two smaller trucks that had preceded it. Through branches and past heavy limbs draped with leaves, Lucy-Anne could see its shape, and it was huge. It reminded her of an oil tanker, but its heavy grey sides looked daunting, the three conical towers on its back ugly and threatening with the stubby black guns that protruded from them. The engine tone lowered for a moment and she thought it was going to slow.

“They can't have seen us!” Emily said, almost shouting to be heard.

Lucy-Anne delved into her pocket for the knife Sparky had let her keep, laughing out loud at how ineffective it felt.

Then the giant vehicle lumbered on, putting on a surprising spurt of speed as it skirted the square and disappeared after the 4?4s.

For a couple of minutes after the lights disappeared and the vehicles were out of sight, everyone remained where they were. Lucy-Anne listened to the engines fading away, echoes coming back at them and playing tricks with direction and distance. Then Rosemary crawled across to them, her eyes wide, fearful, and perhaps excited as well. “Choppers!” she said. “And that big monster was one of their mobile labs. I've watched Irregulars taken into there, never to be seen again.”

“We need to go to your house,” Jack said. Emily was still shivering in his arms. “It's been a long day, Rosemary, and we need rest. This is all too much.”

“Near miss, eh?” Sparky said, crawling across to them.

“Got it all on here, I think,” Emily said, holding up her camera and smiling weakly.

“There won't be another patrol for a while,” Rosemary said.
