One

The tiger slunk away, the frayed rope of its tail trailing behind it.

Jane exhaled slowly and rubbed his face with his hands. The smell of ink and soil and dust. He pressed the heels of his hands into his closed eyes for so long that he saw motes of colour spawn from the black. It reminded him of the weird light show he had seen all those years ago, standing at the bottom of the sea.

Jane opened his eyes. He blinked, but everything was blurred. Eventually, the soft edges regained their shape, except for one. Stopper sat next to him. Jane stared at his old friend, leaning forward over his forearms, which had withered to useless air-dried limbs, like Parma hams carved back to bone. Severed tendons had caused his hands to contract into famished fists. Stopper's face had been sucked clean by marine life. There was little left to distinguish him. The perished yellow Henrikson Subsea logo clung to the tatters of his jacket; it could be nobody else. He smiled, or grimaced, and black water drizzled from between his teeth. Something churned in the wet black reaches of his left eye socket, something with cilia. Something that made hard little skritting noises as it scraped parts of itself against Stopper's orbit.

'He warn't delivered t'me,' Stopper managed, and his voice was little more than the hiss of fossil-fuel ghosts released from ancient pockets in the seabed. His hair danced as if slowly animated by deep water. 'None of your kin fell t'me. S'all right, big man. S'all righhhh.'

Jane leant into his old friend, feeling his tears come. He wondered if he would ever cry himself dry, if that were at all possible. Stopper threatened to topple over, but managed to right himself. Jane smelled marine, deep water, the high ruin of matter that has fermented to oil over millennia. There was beauty in it, Jane supposed, as he felt the familiar weariness drag him down. You could be the ugliest, nastiest, most miserable piece of shit known to man, but if you had a beating heart there was always a chance you'd turn into a diamond after a million years. Everyone was composed of stardust, the random, immeasurable collision of atoms. We'd return to it again one day. He'd be reunited with Stanley then, that was for sure.

He fell asleep to that thought and woke up, seemingly seconds later, more refreshed than he had been for months. He gazed down at the spot where Stopper had been sitting and saw a thin film of oil on the waterproof surface of the roof, a rainbow shifting through it.

His head was thumping; he remembered to breathe.

Stupid, though. A stupid thing to do, to fall asleep on duty. He was glad of the rifle as he crept down through the opera house, pausing at the mouth of the auditorium as if there had been some minuscule sound, that just yards away in the vast black space were hundreds of people in the slashed, scorched seats, the wings and the gods, staring back at him in silence, waiting for the heavy velvet curtains to peel open and reveal the future.

He stepped, shaking, on to Saint Martin's Place. The dark was something almost solid between the buildings; moving through it was slow business. It clung to the lungs like tar. His head was craned out in front of him; he strained for any and every sound. All he could think was orange. He tried to recall the safe houses nearby but drew blanks at every remembered alley and aisle on the A–Z. There would be help in his bible if only he had a flame to read it by.

Cautiously, for want of any better idea, and in need to keep moving, Jane walked south. He might as well deliver the recent pages of his letter to the safeboxes at the hotel. He tried to remember which roads he was walking along, knowing that to get lost at night was to feed yourself to the Skinners. As long as he continued in this direction he would hit the water, and then things would become a little easier.

The things we know, he thought to himself as he hugged the walls. The things we don't.

We know you came from the Event, with the Event. You spread yourself wide and we thought you were dust. You settled in the damp folds of dead bodies. You found the deepest parts of lungs that would never breathe again. You coated everything in the way ash from a catastrophic volcanic eruption that travels around the globe does. You were both seed and preservative; after all, what use is a body without meat on it for a newborn to hatch into?

Everything indoors, untouched by your dust, your seed, decayed. You exploded into life within the husks of the dead. You exploded into life within the bodies of the living. You assumed the shape of the thing you grew inside. I have seen horses, dogs, a crocodile. A tiger. No birds.

You fed well, although you do not eat skin. Perhaps its taste is repellent. Perhaps you are incapable of digesting it. You fill the skins of your victims so that you wear them like the shell of a hermit crab, or maybe it's to do with decoration, or bragging rights. A modern-day scalp. In London, and no doubt in towns and cities all around the planet, millions, billions have been resurrected to seek food, to bring down the survivors.

You cannot see. You cannot speak. You are afraid of nothing, save fire. You are bioluminescent, like some fish. You are translucent. Sometimes it is possible to see clearly into you, to look at what you are digesting.

You kill and eat males on the spot. You incapacitate women and take them away. Why? Do you store them for later? Does female flesh taste better after it has been hung?

What will you do when we are all gone? Will you turn to dust and blow away again on solar winds at the end of our planet's life? Will you travel for light years in stasis, waiting until you happen upon another paralysed Earth?

Jane had hoped that distracting himself with facts might help his progress, but now he saw it was hampering it badly. He was almost crippled with terror. The thought, entertained on countless occasions, that Stanley had been riven by one of these creatures, either directly as a snack or via the unholy germination of its seed, never lost its potency. It gutted him every time. To stumble upon his son one day and find not the Stanley he loved but some shambling, pyjama-clad scarecrow was enough to make him want to leap from any of the tall buildings he favoured staying in. He would kill Stanley, quickly, if that was the case. Kill his son and then commit suicide. He almost fainted and had to slap himself awake in the middle of what he was sure was Northumberland Avenue to even briefly consider allowing his son – what his son had become – to feed on his dad, to get a head start. Eat up Stan, get big and strong for Daddy. This is protein. This will give you muscles.

He reached Victoria Embankment and could just make out the patterns of the current in the skin of the river. Things floated past that he was glad – even now, after so many years of disgust – he could not see. He turned left, heading east. Waterloo Bridge within stumbling distance. Everything was dark apart from the occasional candle in a high-rise window. It reminded him of midnight train journeys through the Pennines when there was little around but the suggestion of hills, a slightly deeper shade of black against that which they rose before. A distant brief orange brick was a farmhouse window. Then nothing but black again.

No figures he could see or hear on the bridge. No animal smell. No stripes. He picked up his pace and by the time he reached the steps up to the bridge he was sprinting. Left up Lancaster Place to the Strand. Now he saw Skinners. He almost stumbled into a party of them trying to separate a figure from its skin but they were having trouble getting it over the angles of its hips. They were quiet, intent. The silence always dismayed Jane. Even when there was a struggle of some sort they did not display any evidence of effort. One of the Skinners had given up peeling and had buried its face into the shining membrane on the figure's lower back that contained the fatty kidneys.

They were too engrossed to register Jane. He backed away and hit Aldwych at full tilt. He was inside what remained of the swing doors of the hotel before he could meet a phalanx of Skinners coming the other way, from the direction of Kingsway. A cocktail bar to the left of the foyer resembled the scene of a water-pistol fight played out with gallons of blood. To the right, the reception desk was spotlessly clean.

Jane took the stairs to the top floor. The Dome Suite was locked; he had a key. He let himself in and felt the tension of the last half an hour fall from him. He felt safe here, one of a few places he had claimed for himself, or that other survivors had not yet become aware of. He'd fight off any challenger to this place. From the boardroom you could look out over the Strand and Waterloo Bridge. Windows to the east of the room gave you an unhindered view of the area around Temple, while to the left you could check along Wellington Street as it sloped into Theatreland.

He unlocked one of two dozen safeboxes lined up in the boardroom and carefully placed the pages of his letter to Stanley inside. On the lid was a number indicating that this was the latest collection. He placed his journal notes for the Shaded on top – they could go to Heathrow with him in the morning – and took off his clothes. In the expansive sitting area, he poured himself a drink and wished he had one of Plessey's radios with him. He wished for
