'They live in town?'

'Five miles west. There are a lot of them. Kind of camping out. Generally they keep themselves to themselves, but people don't like them.'

Reacher said, 'The dead guy was one of them.'

Peterson said, 'Apparently.'

'So maybe they're looking for their buddy.'

'Or for justice.' Peterson watched and waited. Thirty feet ahead the body language ballet continued as before. Chief Holland was shivering. With cold, or fear.

Or both.

Reacher said, 'You better do something.'

Peterson did nothing.

Reacher said, 'Interesting strategy. You're going to wait until they freeze to death.'

Peterson said nothing.

Reacher said, 'Only problem is, Holland will freeze first.'

Peterson said nothing.

'I'll come with you, if you like.'

'You're a civilian.'

'Only technically.'

'You're not properly dressed. It's cold out.'

'How long can it take?'

'You're unarmed.'

'Against guys like that, I don't need to be armed.'

'Crystal meth is not a joke. No inhibitions.'

'That just makes us even.'

'Users don't feel pain.'

'They don't need to feel pain. All they need to feel is conscious or unconscious.'

Peterson said nothing.

Reacher said, 'You go left and I'll go right. I'll turn them around and you get in behind them.'

Thirty feet ahead Holland said something and the two guys crowded forward and Holland backed off and tripped and sat down heavily in the snow bank. Now he was more than an arm's length from where his gun must have fallen.

Half past ten in the evening.

Reacher said, 'This won't wait.'

Peterson nodded. Opened his door.

'Don't touch them,' he said. 'Don't start anything. Right now they're innocent parties.'

'With Holland down on his a.s.s?'

'Innocent until proven guilty. That's the law. I mean it. Don't touch them.' Peterson climbed out of the car. Stood for a second behind his open door and then stepped around it and started forward. Reacher matched him, pace for pace.

The two guys saw them coming.

Reacher went right and Peterson went left. The car had been a comfortable seventy degrees. The evening air was sixty degrees colder. Maybe more. Reacher zipped his jacket all the way and shoved his hands deep in his pockets and hunched his shoulders so that his collar rode up on his neck. Even so he was shivering after five paces. It was beyond cold. The air felt deeply refrigerated. The two guys ahead stepped back, away from Holland. They gave him room. Holland struggled to his feet. Peterson stepped alongside him. His gun was still holstered. Reacher tracked around over the thin white glaze and stopped six feet behind the two guys. Holland stepped forward and dug around in the snow bank and retrieved his weapon. He brushed it clean and checked the muzzle for slush and stuck it back in his holster.

Everyone stood still.

The shaved snow on the street was part bright white powder and part ice crystals. They shone and glittered in the moonlight. Peterson and Holland were staring straight at the two guys and even though he was behind them Reacher was pretty sure the two guys were staring right back. He was shivering hard and his teeth were starting to chatter and his breath was fogging in front of him.

n.o.body spoke.

The guy on Reacher's right was more than six feet tall and close to four feet wide. Some of the bulk was goose-feather insulation in the black winter parka, but most of it was flesh and bone. The guy on Reacher's left was a little smaller in both directions, and more active. He was restless, moving from foot to foot, twisting at the waist, rolling his shoulders. Cold, for sure, but not actively shivering. Reacher guessed the twitching was all about chemistry, not temperature.

n.o.body spoke.

Reacher said, 'Guys, either you need to move right along, or one of you needs to loan me a coat.'

The two men turned around, slowly. The big guy on the right had a white slab of a face buried deep in a beard. The beard was rimed with frost. Like a polar explorer, or a mountaineer. The smaller guy on the left had two days of stubble and jumpy eyes. His mouth was opening and closing like a goldfish pecking at the surface. Thin mobile lips, bad teeth.

The big guy on the right asked, 'Who are you?'

Reacher said, 'Go home. It's too cold for foolishness on the street.'

No reply.

Behind the two guys Peterson and Holland did nothing. Their guns were holstered and their holsters were snapped shut. Reacher planned his next moves. Always better to be prepared. He antic.i.p.ated no major difficulty. He would have preferred the bigger guy to be on his left, because that would have maximized the impact from a right-handed blow by allowing a marginally longer swing, and he always liked to put the larger of a pair down first. But he was prepared to be flexible. Maybe the jittery guy should go down first. The bigger guy was likely to be slower, and maybe less committed, without the chemical a.s.sistance.

Reacher said, 'Coat or float, guys.'

No answer from the two men. Then behind them Chief Holland came to life. He stepped forward one angry pace and said, 'Get the h.e.l.l out of my town.'

Then he shoved the smaller guy in the back.

The smaller guy stumbled towards Reacher and then braced against the motion and spun back and started to whirl a fast one-eighty towards Holland with his fist c.o.c.king behind him like a pitcher aiming to break the radar gun. Reacher caught the guy by the wrist and held on for a split second and then let go again and the guy staggered through the rest of his turn all unbalanced and uncoordinated and ineffectual and ended with a weak late swing that missed Holland entirely.

But then he turned right back and aimed a second swing straight at Reacher. Which in Reacher's opinion took the whole innocent-until-proven-guilty thing right off the table. He stepped left and the incoming fist buzzed by an inch from his chin. The force behind it spun the guy onward and Reacher kicked his feet out from under him and dumped him face down on the ice. Whereupon the bigger guy started wading in, huge thighs, short choppy steps, fists like hams, trumpets of steam from his nose like an angry bull in a kid's picture book.

Easy meat.

Reacher matched the guy's charge with momentum of his own and smashed his elbow horizontally into the middle of the white s.p.a.ce between the guy's beard and his hairline. Like running full tilt into a scaffolding pipe. Game over, except the smaller guy was already up on his knees and scrabbling for grip, hands and feet, like a sprinter in the blocks. So Reacher kicked him hard in the head. The guy's eyes rolled up and he toppled sideways and lay still with his legs folded under him.

Reacher put his hands back in his pockets.

Peterson said, 'Jesus.'

The two guys lay close together, black humps on the moonlit ice, steam rising off them in a cloud. Peterson said nothing more. Holland stalked back to his unmarked car and used the radio and came back a long minute later and said, 'I just called for two ambulances.'

He was looking straight at Reacher.

Reacher didn't respond.

Holland asked, 'You want to explain why I had to call for two ambulances?'

Reacher said, 'Because I slipped.'

'What?'

'On the ice.'

'That's your story? You slipped and just kind of blundered into them?'

'No, I slipped when I was. .h.i.tting the big guy. It softened the blow. If I hadn't slipped you wouldn't be calling for two ambulances. You'd be calling for one ambulance and one coroner's wagon.'

Holland looked away.

Peterson said, 'Go wait in the car.'

The lawyer went to bed at a quarter to eleven. His children had preceded him by two hours and his wife was still in the kitchen. He put his shoes on a rack and his tie in a drawer and his suit on a hanger. He tossed his shirt and his socks and his underwear in the laundry hamper. He put on his pyjamas and took a leak and brushed his teeth and climbed under the covers and stared at the ceiling. He could still hear the laugh in his head, from the phone call just before he spun out on the highway. A bark, a yelp, full of excitement. Full of antic.i.p.ation. Full of glee. Eliminate the witness Eliminate the witness, he had recited, and the man on the phone had laughed with happiness.

Reacher got back in Peterson's car and closed the door. His face was numb with cold. He angled the heater vents up and turned the fan to maximum. He waited. Five minutes later the ambulances showed up, with flashing lights pulsing bright red and blue against the snow. They hauled the two guys away. They were still out cold. Concussions, and probably some minor maxillary damage. No big deal. Three days in bed and a cautious week's convalescence would fix them up good as new. Plus painkillers.

Reacher waited in the car. Thirty feet ahead of him through the clear frigid air he could see Holland and Peterson talking. They were standing close together, half turned away, speaking low. Judging by the way they never glanced back, Reacher guessed they were talking about him.

Chief Holland was asking: 'Could he be the guy?'

Peterson was saying, 'If he's the guy, he just put two of his presumptive allies in the hospital. Which would be strange.'

'Maybe that was a decoy. Maybe they staged it. Or maybe one of them was about to say something compromising. So he had to shut them up.'

'He was protecting you, chief.'

'At first he was.'

'And then it was self-defence.'

'How sure are you he's not the guy?'

'One hundred per cent. It's just not feasible. It's a million-to-one chance he's here at all.'

'No way he could have caused the bus to crash right there?'

'Not without running up the aisle and physically attacking the driver. And no one said he did. Not the driver, not the pa.s.sengers.'

'OK,' Holland said. 'So could the driver be the guy? Did he crash on purpose?'

'h.e.l.l of a risk.'

'Not necessarily. Let's say he knows the road because he's driven it before, summer and winter. He knows where it ices up. So he throws the bus into a deliberate skid.'

'A car was coming right at him.'

'So he says now.'

'But he could have been injured. He could have killed people. He could have ended up in the hospital or in jail for manslaughter, not walking around.'

'Maybe not. Those modern vehicles have all kinds of electronic systems. Traction control, antilock brakes, stuff like that. All he did was fishtail around a little and drive off the shoulder. No big deal. And then we welcomed him with open arms, like the Good Samaritan.'

Peterson said, 'I could talk to Reacher tonight. He was a witness on the bus. I could talk to him and get a better picture.'

Holland said, 'He's a psychopath. I want him gone.'

'The roads are closed.'

'Then I want him locked up.'

'Really?' Peterson said. 'Tell the truth, chief, he strikes me as a smart guy. Think about it. He saved you from a busted nose and he saved me from having to shoot two people. He did us both a big favour with what he did tonight.'

'Accidentally.'

'Maybe on purpose.'

'You think he knew what he was doing? Right there and then?'

'Yes, I think he did. I think he's the sort of guy who sees things five seconds before the rest of the world.'

'Are you serious?'

'Yes, sir. I've spent a little time with him.'

Holland shrugged.

'OK,' he said. 'Talk to him. If you really want to.'

'Can we use him for more? He's ex-military. He might know something.'
