Someone shouted a strangled warning just before the driverless vehicle rammed through the double doors in a shower of glass, then continued on across the atrium before ramming into the reception desk. The sound of the impact was loud enough to drown out even the wail of the alarm.

Jeff felt the intense pressure on his back suddenly relax. The three guards seemingly had forgotten them, and were firing wildly at the van, while backing away from it. Clouds of choking black smoke spilled out of the van’s windows and began to fill the entire atrium. Though several large windows shattered under the impact of stray bullets, it was a still and windless night, so the smoke lingered, quickly reducing visibility to barely more than a few metres in any direction.

Jeff scrambled upright, while Present-Mitchell simply stared around in abject confusion. Whatever they’d been pumping into his veins, Jeff reckoned, it must have been powerful stuff. He leaped up, and once again helped the other man to his feet. They then stumbled out through a shattered floor-to-ceiling window, and into the cold night air, coughing desperately.

Jeff heard the screech of rubber on tarmac, and turned to see the sedan that Mitchell had stolen come bumping down the manicured slope separating the Arcorex building from its car park. It swerved to avoid several bushes, then crashed to a halt at the foot of the slope. Future-Mitchell leaned out of the driver’s window, gesturing frantically.

While Jeff dragged his half-comatose ward after him, Future-Mitchell jumped out and took hold of his doppelgänger’s other arm, helping Jeff guide him into the back seat, where he slumped with a groan. Shouting erupted from behind.

Future-Mitchell slid back behind the wheel and reversed hard, before Jeff had a chance to pull himself fully on to the front passenger seat. The sedan accelerated backwards, at an angle, up the landscaped slope, and Jeff managed to haul himself all the way inside just as the vehicle came crashing down level again at the top of the slope. Gunfire sliced the chill air, and a rear passenger window exploded to his right. Jeff immediately ducked, the side door still swinging open as Future-Mitchell spun the vehicle through a hundred and eighty degrees.

‘Keep your fucking heads down!’ he screamed, twisting the wheel.

The sedan rammed into something Jeff couldn’t see, slewed around, then accelerated away once more. As the door swung back towards Jeff, he managed to grab hold of it, finally pulling it shut as further shots echoed around them. He hunched over, paralysed with fear, as he imagined those bulles tearing into his own soft and vulnerable flesh.

The car screeched to a sudden halt, then accelerated once more. Jeff pulled himself slowly upright, to see they were back on the highway.

‘I think we’re out of range now,’ announced Future-Mitchell, with a look of grim determination. ‘How is he?’
