She came to a halt in front of the broad stone stairs leading up to the marble portico and dismounted. Luca took the reins, doing his best to soothe the agitated beast.

“We’ve just had word from the villages along the railway,” she said. “There’s a bunch of marauders heading this way. Colsterworth council respectfully requests, and all that bullshit. Luca, we need some help to see the bastards off. Apparently they’re armed. Raided an old militia depot on the outskirts of Boston, got away with rifles and a dozen machine guns.”

“Oh, this is fucking brilliant,” Luca said. “Life here just keeps getting better and better.”

Luca studied the train through his binoculars (genuine ones, handed down to Grant by his father). He was sure it was the same one as before, but there had been changes. Four extra carriages had been added, not that anyone travelled in comfort. This was an iron battle wagon whose armour plates (genuine, Luca thought) ran along its entire length, riveted crudely around ordinary carriages. It clanked along the rail track towards Colsterworth at an unrelenting thirty miles an hour. Bruce Spanton had finally managed to turn the concept of an irresistible force into a physical entity, putting it down straight into Norfolk’s Turneresque countryside where it didn’t belong.

“There’s more of them this time,” Luca said. “I suppose we could roll the rails up again.”

“That monstrosity isn’t built for reversing,” Marcella said grimly. “You have to turn the minds around, their tails will follow.”

“Between their legs.”

“You got it.”

“Ten minutes till they get here. We’d better get people into position and dream up a strategy.” He’d brought nearly seventy estate workers with him from Cricklade. The announcement by Colsterworth Council had resulted in over five hundred townsfolk volunteering to fight off the marauders. Another thirty or so had gathered from outlying farms, determined to protect the food they’d worked hard to gather. All of them had brought shotguns or hunting rifles from their adopted homes.

Luca and Marcella organized them into four groups. The largest, three hundred strong, were formed up in a horseshoe formation surrounding Colsterworth station. Two outlying parties were hanging back from the cusps, ready to swarm across the rail and encircle the marauders. The remainder, three dozen on horseback, made up a cavalry force ready to chase down anyone who escaped from the attack.

They spent the last few minutes walking along the ranks, getting them into order and making sure they had all hardened their clothes into bullet-proof armour. Real gunshots were harder to ward off in this realm. Carbosilicon-reinforced flak-jackets were the popular solution, making the front line take on the appearance of a police riot brigade from the mid-Twenty-first Century.

“It’s our right to exist as we choose that we’re standing for,” Luca told them repeatedly as he walked along, inspecting his troops. “We’re the ones who’ve made something of these circumstances, built a decent life for ourselves. I’ll be buggered if I’m going to let this rabble wreck that. They cannot be allowed to live off us, that makes us nothing more than chattel.”

Everywhere he went, he received murmurs and nods of agreement. The defenders’ resolution and confidence expanded, building into a physical aura which began to tint the air with a hearty red translucence. When he took up position with Marcella they simply grinned at each other, relishing the fight. The train was only a mile out of town now, coming round the last bend onto the straight leading to the station. It tooted its whistle in an angry defiant blast. The red haze over the station glowed brighter. A crack split open along the middle of the wooden sleepers, starting five yards from Luca’s feet and extending out past the end of the platforms. It opened barely six inches, and halted, quivering in anticipation. Granite chippings trickled over the edges, to be swallowed silently by the abyssal darkness which had been uncovered.

Luca stared directly at the front of the train, facing down its protruding cannon barrels. “Just keep coming, arsehole,” he said quietly.

Subtlety simply wasn’t an option. Both sides knew the rough strengths and position of the other. It could never be anything other than a direct head-to-head confrontation. A contest of energistic strength and imagination, with the real guns an unwelcome sideshow.

Half a mile from the station, and the train slowed slightly. The rear two carriages detached and braked to a halt amid fantails of orange sparks from their locked wheels. Their sides hinged down to form ramps, and jeeps raced down onto the ground. They’d been configured into armour-plated dune buggies with thick roll bars; huge deep-tread tyres were powered from four-litre petrol engines that spurted filthy exhaust fumes out into the air with a brazen roar. Each one had a machine gun mounted above the driver, operated by a gunner dressed in leather jacket with flying goggles and helmet.

They sped away from the carriages in an attempt to outflank the townie defenders. Luca gave a signal to his own cavalry. They charged out into the fields, heading to intercept the jeeps. The train kept thundering onwards.

“Get ready,” Marcella shouted.

Puffs of white smoke shot out from the train’s cannon. Luca ducked down in reflex, hardening the air around himself. Shells started to explode at the end of the station, thick plumes of earth smearing the blank skyline amid bursts of orange light. Two struck the fringe of red air, detonating harmlessly twenty yards above the ground. Shrapnel flew away from the protective boundary. A cheer rang out from the defenders.

“We got ’em,” Luca growled triumphantly.

Machine gun fire rattled across the fields as the jeeps raced round in tight curves, churning up furrows of mud. They drove straight through gates, bursting the timber bars apart with a flash of white light. Horses cantered after them, jumping the hedges and walls effortlessly. Their riders were shooting from the saddle, as well as flinging bolts of white fire. The jeep engines started to cough and stutter as fluxes of energistic power played hell with the power cells encased deep within the semisolid illusion.

The train was only a quarter of a mile away now. Its cannon were still firing continuously. The land beyond the end of the station was taking the full brunt of the impact: craters erupted continuously, sending soil, grass, trees, and stone walls ploughing though the air. Luca was surprised at the diminutive size of the craters, he’d expected the shells to be more powerful. They did produce a lot of smoke, though; thick grey-blue clouds churning frenetically against the sheltering bubble of redness. They almost obscured the train from view.

Luca frowned suspiciously at that. “They could be a cover,” he shouted at Marcella above the bass thunder of exploding shells.

“No way,” she yelled back. “We can sense them, remember. Smoke screens don’t work here.”

Something was wrong, and Luca knew it. When he switched his attention back to the train, he could sense the note of triumph emanating from it, just as strong as his own. Yet nothing the marauders had done assured them of victory. Nothing he could perceive.

Layers of smoke from the shells were creeping sluggishly towards the station. As they slithered through the edge of the red light they gleamed with a dark claret phosphorescence. People in the reserve groups clustered outside the platforms were reacting strangely as the first wisps curled and flexed around them. Waving their hands in front of their faces as if warding off a mulish wasp, they began to stagger around. Ripples of panic raced out from their minds, impinging against those close by.

“What’s happening to them?” Marcella demanded.
