Knox said, ‘A car coming the other way was sliding all over the place. I twitched.’ His tone was slightly defensive. Peterson gave him a look full of sympathy and empty of judgement and nodded again. He said, ‘A twitch will usually do it. It’s happened to lots of people. Me included.’

Reacher said, ‘We need to get these people off this bus. They’re going to freeze to death. I am, too.’

Peterson was quiet for a long second. There’s no connection between us and whatever it is that’s on your mind. Then he nodded again, definitively, like his mind was made up, and he called out, ‘Listen up, folks. We’re going to get you to town, where we can look after you properly. The lady with the collar bone and the lady with the wrist will come with me in the car, and there will be alternative transportation right along for the rest of you.’

The step down into the ditch was too much for the injured women, so Peterson carried one and Reacher carried the other. The car was about ten yards away, but the snow was so thick by then that Reacher could barely see it, and when he turned back after Peterson had driven away he couldn’t see the bus at all. He felt completely alone in the white emptiness. The snow was in his face, in his eyes, in his ears, on his neck, swirling all around him, blinding him. He was very cold. He felt a split second of panic. If for some reason he got turned around and headed in the wrong direction, he wouldn’t know it. He would walk until he froze and died.

But he took a long step sideways and saw the crimson haloes of the flares. They were still burning valiantly. He used them to work out where the bus must be and headed for it. Came up against its leeward side and tracked around the front, back into the wind, through the ditch to the door. Knox let him in and they crouched together in the aisle and peered out into the darkness, waiting to see what kind of a ride had been sent for them.

Five to six in the evening.

Fifty-eight hours to go.

At six o’clock the fourteen criminal proposals finally made it to paper. The guy who had answered the lawyer’s call was plenty bright in a street-smart kind of way, but he had always figured that the best part of intelligence was to know your limitations, and his included a tendency to get a little hazy about detail when under pressure. And he was going to face some pressure now. That was for damn sure. Turning proposals into actions was going to require the sanction of some seriously cautious people.

So he wrote everything down, fourteen separate paragraphs, and then he unplugged a brand-new untraceable pay-as-you-go cell from its charger and started to dial.

The ride that had been sent for them was a school bus, but not exactly. Definitely a standard Blue Bird vehicle, normal size, normal shape, regular proportions, but grey, not yellow, with heavy metal mesh welded over the windows, and the words Department of Corrections stencilled along the flanks.

It looked almost new.

Knox said, ‘Better than nothing.’

Reacher said, ‘I’d go in a hearse if it had a heater.’

The prison vehicle K-turned across all three lanes and sawed back and forth for a while until it was lined up exactly parallel with the dead bus, with its entrance step about halfway down the dead bus’s length. Reacher saw why. The dead bus had an emergency exit, which was a window panel ready to pop out. Peterson had seen the ditch and the passengers and the panel, and had made a good decision and called ahead. Peterson was a reasonably smart guy.

Normally eighteen random seniors might have needed an amount of coaxing before stepping through an open hatch into a blizzard and the arms of a stranger, but the bitter cold had quieted their inhibitions. Knox helped them up top, and Reacher lifted them down. Easy work, apart from the cold and the snow. The lightest among the passengers was an old guy not more than ninety-five pounds. The heaviest was a woman closer to two hundred. The men all wanted to walk the short distance between the two vehicles. The women were happy to be carried.

The prison bus might have been almost new, but it was far from luxurious. The passenger area was separated from the driver by a bright steel cage. The seats were narrow and hard and faced with shiny plastic. The floor was rubber. The mesh over the windows was menacing. But there was heat. Not necessarily a kindness from the state to its convicts. But the bus manufacturer had built it in, for the school kids that the vehicle was designed to carry. And the state had not ripped it out. That was all. A kind of passive benevolence. The driver had the temperature turned up high and the blower on max. Peterson was a good advance man.

Reacher and Knox got the passengers seated and then they ducked back out into the cold and hauled suitcases out of the dead bus’s luggage hold. The old folks would need nightwear and prescriptions and toiletries and changes of clothes. There were a lot of suitcases. They filled the prison bus’s spare seats and most of the aisle. Knox sat down on one. Reacher rode standing next to the driver, as close to a heater vent as he could get.

The wind buffeted the bus but the tyres had chains and progress was steady. They came off the highway after seven miles and rumbled past a rusted yield sign that had been peppered by a shotgun blast. They hit a long straight county two-lane. They passed a sign that said Correctional Facility Ahead. Do Not Stop For Hitchhikers. The sign was brand new, crisp and shiny with reflective paint. Reacher was not pleased to see it. It would make moving on in the morning a little harder than it needed to be.

The inevitable question was asked less than a minute later. A woman in the front seat looked left, looked right, looked a little embarrassed, but spoke anyway. She said, ‘We’re not going to be put in jail, are we?’

‘No, ma’am,’ Reacher said. ‘A motel, probably. I expect this was the only bus free tonight.’

The prison driver said, ‘Motels are all full,’ and didn’t speak again.

Five to seven in the evening.

Fifty-seven hours to go.

The county two-lane ran straight for more than ten miles. Visibility was never more than ten yards at a time. The falling snow was bright in the headlight beams, and beyond it was guesswork. Flat land, Reacher figured, judging by the unchanging engine note. No hills, no dales. Just prairie, flattened further by what was surely going to be a whole extra foot of snow by the morning.

Then they passed a sign: Bolton City Limit. Pop. 12,261. Not such a small place after all. Not just a dot on the map. The driver didn’t slow. The chains chattered onward, another mile, then another. Then there was the glow of a street lamp in the air. Then another. Then a cop car, parked sideways across the mouth of a side street, blocking it. The car had its red roof lights turning lazily. The car had been stationary for a long time. That was clear. Its tyre tracks were half full of fresh snow.

The bus clattered on for another quarter-mile and then slowed and turned three times. Right, left, right again. Then Reacher saw a low wall, with a loaf of snow on top and a lit sign along its length: Bolton Police Department. Behind the wall was a big parking lot half full with civilian vehicles. Sedans, trucks, crew-cab pick-ups. They all looked recently driven and recently parked. Fresh tyre tracks, clear windshields, melting slush on their hoods. The bus eased past them and slowed and came to a stop opposite a lit entrance lobby. The engine settled to a noisy idle. The heater kept on going. The police station was long and low. Not a small operation. The roof was flat and had a forest of antennas poking up through the snow. The lobby door was flanked by a pair of trash cans. Like two proud sentinels.

The lobby looked warm.

The prison driver hauled on a handle and opened the bus door and a guy in a police parka came out of the lobby with a snow shovel and started clearing the path between the trash cans. Reacher and Knox started hauling suitcases out of the aisle, out of the bus, into the police station. The snow was letting up a little but the air was colder than ever.
