Then they were standing over him. Half a dozen young lads wearing neon orange vests that made them look like a highways maintenance crew; except, that is, for the guns they were each brandishing.

‘Go on, piss off, you wankers!!’ shouted one of them, firing a few rounds indiscriminately into the stampeding mass of children. He watched them go, tumbling over the plastic palm tree and disappearing down avenues between the corporate stands before finally shining a flashlight down at Nathan.

‘You all right, bro?’

Nathan looked up. A young black man, he looked older than him; at a guess mid-twenties. Long thick dreadlocks cascaded from beneath a red Nike bandanna and a chunky gold chain glistening around his neck.

Nathan managed a hasty nod. He glanced back down at Jacob’s body on the floor. ‘My friend’s . . . they . . . I think he’s hurt badly.’

The black guy stooped down to the floor and flicked his flashlight across the prone form. ‘He with you?’ he asked.

Nathan nodded silently, his mouth hung open, still in shock at the last minute reprieve.

‘Lemmesee,’ the young man said. His hand flicked a blood-soaked lock of Jacob’s hair out of the way and reached around under his jawline as if he was attempting to throttle him. He fumbled for a moment, adjusted his grip around the neck several times, narrowing his eyes in concentration as he felt for a pulse.

‘Ain’t dead, bro,’ he said after a while. He turned round. ‘Jay-zee, get him on to the cart.’

A tall black lad barked an order at two younger boys. They passed their guns to a colleague, stepped forward and scooped Jacob’s body up between them.

‘We takin’ him home, Snoop?’ asked one of them, a white kid who looked several years younger than the one with the bandanna - clearly their leader. He also sported a thick gold choke chain.

Snoop nodded. ‘Yuh, Tricky, we takin’ him back. We take him to get the doc’ see to him.’

He turned to Nathan. ‘You comin’, too.’

Not a request, it seemed. An order. He looked down at the assault rifle still clutched tightly in Nathan’s hands. ‘Hey, nice gun, bro. Lemmesee it.’

Nathan passed it up to him, looking over his shoulder as he stood up. The other two were hefting Jacob away between them up the concourse.

The black guy nodded approvingly at the weapon. ‘Army gun. Kept nice an’ clean. This your piece?’

Nathan nodded.

‘Good gun-care, bro. May be that the Chief will wanna make you a praetorian.’ He flicked his head. ‘Come.’

Nathan’s gaze returned to him. ‘Who . . . who are you?’

‘Me?’ he grinned. ‘You call me Snoop - the top dog. You?’

‘Nathan Williams.’

‘What about the white kid?’

‘Jacob Sutherland.’

Snoop shrugged. ‘Okay, Nathan Williams, we’re goin’ before them wild fuckin’ rugrats return. Like fuckin’ mosquitoes way they keep comin’ back here.’

He followed after the others, walking backwards swinging his torch to and fro and keeping a wary eye out for the feral children.

‘Where we goin’?’ asked Nathan, stepping smartly to keep pace with them.

‘Take you back to the Zee.’

‘The Zee?’

‘Yuh. Zee . . . the Zone. Where we live. Ain’t far.’

‘Jay . . . Jacob, my friend, he’s going to be all right, isn’t he?’

Snoop shrugged. ‘Fucked if I know. Doc’ll look him over when we get back.’

They stepped out of the main hall, down several wide steps into a foyer lined with registration desks and turnstiles and across a floor littered with glass granules that crackled underfoot. They pushed their way out through a row of rotating door frames, the panels cracked and lined with shards of glass.

It was almost completely dark now. Waiting patiently just outside the doors, beneath an entrance awning of canvas that stretched off down a long, covered approach promenade, were a pair of ponies harnessed to an improvised cart; the four wheels and a chassis of a car, with a flatbed of planks laid across.

‘We was inside there with someone else,’ said Nathan quickly.

Snoop shrugged again. ‘Well, shit, they’re dead or they run by now. Ain’t my business.’ He barked orders at the others. ‘Get him on the cart.’

The other boys in orange vests eased Jacob onto the cart then clambered on themselves. He turned to Nathan impatiently. ‘Well, get on, unless you want wait around for the rats to come back.’

Nathan cast one last glance back at the dark interior of the ExCel Centre, desperately hoping to see Leona come stumbling out of the gloom, barking at them not to go and leave her behind.

‘What you waitin’ for? Get on, fool, or we’ll go leave you behind.’

Nathan did as he was told, clambered onto the planks and settled down beside Jacob.

Shit. He shook his head and looked down at his friend’s face, criss-crossed with rivulets of tacky drying blood, his breath rattled out though clogged nostrils.

Snoop hopped on the front of the cart and barked an order at one of the other lads. With a shrill whistle and the crack of a stick on their haunches, the ponies lurched forward and the cart spun out from beneath the awning and across the approach. Above them the last stain of dusk’s amber was gone and stars had begun to dimly pepper the night sky.

Nathan clenched his lips, thankful it was dark enough that none of the others sitting beside him were going to notice the silent tumble of tears on his cheeks as he squeezed one of Jacob’s clammy hands.

She remained where she was, silent, her hands grasped the overpass railing, her eyes locked on the building, scanning the empty car-park for any possible shadows of movement coming her way.

An hour might have passed. She had no idea. It could have been longer. In that time a yellow, sickly three-quarter moon had risen and arced some of its way across the night sky. Its wan light glinted off the water of Victoria Docks, smooth and sullen, and every now and then a soft sigh of warm summer breeze stirred through the saplings on the railway bankings below her.

The only thing she knew for certain was that she couldn’t walk away not knowing what had happened to them.

In which case, they’d try and make their way back here. That’s what she would do. The trailer parked at the bottom of the steps was all there was for food. They’d have no other choice than try and find their way back to the bridge.

First Hannah . . . now Jacob. This shitty world seemed fully intent on taking away absolutely everyone she’d ever cared for; taken from her one by one so she could really savour the pain of each loss . . . get to squeeze every last ounce of hurt out before the next one could be snatched away.

Stupidly, for a while yesterday, listening to Take That, the Kaiser Chiefs, the Chili Peppers, even Abba, she’d allowed the gloom to shift ever so slightly. She’d allowed herself to wonder whether she really did want to go home to her old bedroom, snuggle up in whatever was left of her duvet and call it quits. Raymond’s ‘fight-on’ spirit had managed to touch her for a few hours.

Something was telling her she hadn’t lost him . . . yet. That he was alive. But she might be wasting valuable time standing here looking at the back of the building.

The thought terrified her. Those bones . . . and the horrible look of those things, she could barely think of them as children; they were like wraiths, lost souls. No, running in there and getting taken by those feral children wasn’t going to help anyone. She realised the only sensible thing she could do was to stay where she was and watch and wait for the boys’ return.

She had no idea. No plan.

She stood in silence on the bridge, holding on to the handrail, listening to the soft rustle of trees below.

‘Maybe I’ll find him at home?’
