One

Jane kept his eyes on the ground and watched it disappear under his feet. At the English border he passed three flagpoles bearing flapping black scraps; a blistered sign might have bade welcome to his country. He did not look up. He didn't know how far he had walked before the light changed and began to creep across the rocky coastline and seep through the mist, to bring edges to the darkness. He rummaged in cars, trying not to touch their ruptured occupants, until he found a pair of sunglasses in a glove compartment. All the time he was trying to quell his panic, trying to assess himself for the signs of shock. It would be almost criminal to survive whatever had happened only to succumb to heart failure. When the traffic became too much for him to deal with, he cut across a field to the railway. The rain came again; it never really went away, just a variation between gossamer breath and tropical muscle.

At Berwick-upon-Tweed he climbed up onto the railway station platform and angled along Castlegate. He had to step over the bodies of three people who had dropped dead in the entrance of a Somerfield supermarket. The windows had survived but were little more than opaque mosaics. Rats had been at the corpses' faces and fingers. Rats too had ransacked the shelves. Plastic-wrapped loaves of bread had become culture specimens. Popcorn had exploded out of its microwave-ready packaging and created a foam in the aisle. Racks of vacuum-sealed ham slices were molten twists of biltong. Cans were pitted and scarred. He saw a tooth embedded in a plastic container of washing detergent. The newspapers and magazines were shredded, leeched of colour.

The freezers had all failed. The smell of rot permeated the bicycle mask, but it didn't spoil his hunger. He headed into the storage space at the back of the shop; here there were tinned foods that had survived any damage. He wrenched open the thing nearest to him: a can of pilchards; wolfed them down. He hated pilchards, but flavour and texture meant nothing: he couldn't taste anything beyond the chemical coating that layered his throat. He ate a can of corned beef and a can of pears. He felt the flakiness that comes with low blood sugar dissipate. He welcomed the false optimism that always accompanied a full stomach. He searched the delivery bay at the back of the shop and found a dead man who had been welding a broken railing to a gate. His goggles were by his side; Jane put them on, discarding the sunglasses. He transferred a Stanley knife from the tool bag to his rucksack. He moved back through the shop and found a crate of glass bottles of water, shrink-wrapped plastic torched off. He drank half a litre; it tasted funny – maybe it had boiled inside the glass – but he kept it down. He placed a couple of the bottles in his rucksack.

Jane stopped in the town centre at a camping shop and took a waterproof coat and hat. He found some more gloves; the current ones smelled scorched, were already weakened across the backs where the rain had settled. He thought again about a weapon, not for use against any foe – he doubted that the rats would grow any more confrontational – but as reassurance, insurance. He had the Stanley knife but he didn't think he could use that; it would be too much like an insult to Stopper's memory.

He walked down to the parade of shops, but there was no chance of a gun here. Again he thought of breaking into some houses; surely there were hunters in this bucolic part of the country? His own grandfather had owned a shotgun, and he was from industrial Widnes. But he didn't feel as though he could stomach the inevitable bodies. Or perhaps it was something else. Perhaps it was the fear of finding someone alive.

He shuddered, shook the feeling out of himself. It was just an inevitable result of so much open space. You grew used to the silence quickly, especially coming a little inland, away from the waves. You went beyond that super-attenuated aspect, flinching at every sound, every shadow. You learnt the beats of the humdrum quickly. It would spook him now, to see someone moving through the streets, or hear them calling to him from a rooftop. But he had to hold on to the hope. Accidents happened. People survived. It could only be a matter of time.
