'No.'

'I can't leave here.'

'You said we might never hear that siren again. No escapes, no more riots.'

'An educated guess is still a guess.'

'I'll pick you up and bring you straight back.'

'You can't promise that. Suppose the siren sounds while I'm over there?'

'I'll still bring you back. I swear, on the lives of my children.'

'You'd get in trouble.'

'I'll fight it. And I'll win.'

'You should get the department, you know that?' Reacher said. 'The sooner the better.'

Peterson arrived five minutes later. He spoke to his people and then he found Janet Salter and told her he was borrowing Reacher for a quarter of an hour. He looked her in the eye and promised her that none of his officers would leave the house until Reacher was back. She was uneasy, but she seemed to believe him. Reacher put his coat on and climbed into Peterson's car and five minutes after that he was back in the squad room.

Peterson sat down at a desk with a computer and started pointing and clicking and pursing his lips and inhaling and exhaling. He came up with a blank grey square in the middle of the screen. The square had a play arrow laid over its centre portion.

'Surveillance video,' Peterson said. 'From the prison interview room. It's digital. They e-mail it to us.'

'OK.'

'It's the biker and his lawyer. Earlier this afternoon. We never cancelled the surveillance. You know why?'

'Why?'

'Inefficiency.' Peterson moved the mouse and clicked on the play arrow. The grey square changed to a grainy colour picture of the interview room shot from above. The camera was presumably hidden in a light fixture, on the lawyer's side of the gla.s.s part.i.tion. It showed a man in a grey suit sitting forward in his chair with his elbows on the concrete counter and his face a foot from the gla.s.s. Opposite him on the other side of the barrier was a guy in an orange jumpsuit. He was tall and solidly built. He had long black hair and a greying beard. His pose mirrored his lawyer's. Elbows on the counter, face a foot from the gla.s.s.

Conspiratorial.

'Now listen,' Peterson said.

The lawyer said something in a whisper. Reacher couldn't hear it.

'Where's the mike?' he asked.

'In the light with the camera.' Peterson stabbed a key and the computer beeped the volume all the way up. Then he dragged a red dot backwards a fraction and the segment played again. Reacher craned closer. The audio quality was very poor, but this time the lawyer's sentence was at least intelligible.

The lawyer had said, 'You know, the ancient Greeks tell us that a six-hour wait solves all our problems.'

Peterson paused the replay. 'Ancient Greeks, right? Like ancient Greek philosophers? You said Plato was an ancient Greek philosopher. It's a code. It's a message.'

Reacher nodded. 'When was this?'

'Two o'clock this afternoon. So a six-hour wait would take us to eight o'clock. It's six o'clock now. Which gives them two more hours. They've already wasted two-thirds of their time.'

Reacher stared at the screen.

'Play it again,' he said.

Peterson dragged the red dot back. Hit play. The lawyer's head, moving forward an inch. The scratchy, whispery sound. The ancient Greeks tell us that a six-hour wait solves all our problems The ancient Greeks tell us that a six-hour wait solves all our problems.

Reacher said, 'I don't hear it that way. He's not saying we have a six-hour period during which at some random point all our problems might be solved. I think he's saying that six hours from then something specific is going to happen in order to solve them.'

'You think?'

'Just my opinion.'

'What kind of thing will happen?'

'The siren will sound. It's their only way to get at Mrs Salter.'

'How can a lawyer make the siren sound?'

'He can't. But maybe they can together.'

'How?'

'What happens up there at eight o'clock? Are they eating? Feeding time at the zoo is always a good time for a riot.'

'They eat earlier.'

'TV time? An argument about CBS or NBC?'

'You said another riot won't happen.'

'Something is going to happen. That lawyer is talking about a future event with a fairly high degree of confidence.'

Peterson went pale. Papery white, under his reddened winter skin.

'Jesus,' he said. 'Eight o'clock is head-count time. They lock them in their cells for the night and check them off. Suppose that guy got out this afternoon and they don't know it yet? They're going to be one short. One minute past eight, they're going to hit the panic b.u.t.ton.'

They drove straight back to Janet Salter's house. Dinner was almost ready. About ten minutes away. Spaghetti and sauce and cheese, with salad in the old wooden bowl. Janet Salter offered to set an extra place for Peterson. Peterson said yes. But nothing more. He just accepted the invitation and then stepped away from the kitchen activity and took Reacher by the elbow and dragged him into the parlour. He said, 'I'm staying right here when the siren goes off.'

Reacher said, 'Good.'

'Two are better than one.'

'Always.'

'Are you armed?'

'Yes. And so is Mrs Salter.'

'How will their guy arrive?'

'From the front, in a car. Too cold for anything else.'

'Anything we can do ahead of time?'

Reacher said, 'No.'

Peterson said, 'We could warn the prison, I suppose. If the siren went off right now, their guy might be out of position.'

'We don't want him out of position,' Reacher said. 'We want him walking up the driveway at two minutes past eight. Exactly when and where we expect him. You said it yourself, we need this thing to be over.'

Seventeen hundred miles south Plato came out of his house and found the three idling Range Rovers parked in a neat nose-to-tail line. The six men who had come with them were standing easy in pairs, heads up, sungla.s.ses on, hands clasped behind their backs. Plato looked at them carefully. He knew them. He had used them before. They were solid but unspectacular performers. Competent, but uninspired. Not the best in the world. Second-rate, B-students, adequate. There were a lot of words with which to describe them.

He looked at the trucks. Three of them, all identical. British. Each the cost of a college education. Maybe not Harvard. He counted them from the front, one, two, three. Then from the back, three, two, one. He had to choose. He never occupied the same relative position in a convoy two times in a row. Too predictable. Too dangerous. He wanted a two-in-three chance of surviving the first incoming round, if there was to be one. He figured a second round would miss. The supercharged engines had great acceleration. Better than turbocharged. No lag.

He chose car number three. A double bluff, in a way. Slightly counterintuitive. If number one or number two was blown up, number three might get trapped by the flaming wreckage. He would be expected to expect that. He would be presumed to be in car number one, for that very reason. Which burnished his two-in-three chances a little. Convoys opened up at speed. Rack and pinion steering, fast reactions, number three's driver could swerve with plenty of time to spare.

He inclined his head, towards the third car. One of the men standing next to it stepped up smartly and opened the rear door. Plato climbed in. There was a step. Which was necessary, given his stature. He got settled on the rear seat. Cream leather, piped with black. An armrest on the door to his right, an armrest pulled down in the centre of the bench. Air conditioning, set low. Very comfortable.

The two men climbed into the front. Doors closed, a forward gear was engaged. The convoy moved off. The gate was grinding back as they approached it. They slowed, slipped through, sped up. They cruised through the first dusty mile.

Plato looked at the men in front of him.

Many words to describe them.

The best was: disposable.

Janet Salter's kitchen table was cramped for seven people. Peterson and the four women cops had guns on their hips, which made them wide. Reacher himself was not narrow, elbow to elbow. But perhaps as a consequence the atmosphere was cosy. At first Janet Salter was tense, as were Reacher and Peterson for other reasons. The four women cops were happy to talk. Then Janet Salter began to relax, and Reacher and Peterson took a mutual unspoken decision to save it for when it was going to count. They joined in. Everyone told stories. Janet Salter had attended a small local elementary school, a long time ago. The farm boys had been sewn into their winter underwear in November and not released until March. By January the smell was awful. By February it was unbearable.

Peterson's experience had been different. He was half Janet Salter's age. His school was exactly the same as he saw in all the TV shows he watched. He felt part of America, until he looked at a map. Seven hundred miles from the nearest Major League team. A long way from anywhere. Something timid in his head had told him he would never leave. He confessed it quite openly.

Two of the women cops were from North Dakota. They had come south for jobs. And for warmer weather, one said with a smile. Their educations had been similar to Peterson's. Reacher didn't say much. But he knew what they were talking about. Lockers, the gym, the princ.i.p.al's office. He had been to seven elementary schools, all of them overseas on foreign bases, but all of them imported direct from the U.S. as standardized kits of parts. Outside he had been in the steamy heat of Manila or Leyte, or the damp cold of Germany or Belgium, but inside he could have been in North Dakota or South Dakota or Maine or Florida. At times he had been twelve thousand miles from the nearest Major League team. Something in his head had told him he would never stay still.

They had fruit for dessert and coffee and then they cleared the table and washed the dishes, all of them together, part professional, part collegial. Then the day watch women went off duty, and went upstairs. The night watch women headed for the hallway and the library. Janet Salter picked up her book. Reacher and Peterson went to the parlour to wait.

Five minutes to seven in the evening.

Nine hours to go.

CHAPTER THIRTY

PETERSON KEPT CHECKING HIS WATCH. REACHER KEPT TIME IN his head. Seven o'clock. Five past. Ten past. A quarter past. No activity on the street. The view out from under the lip of the porch stayed the same. Snow, ice, wind, Peterson's parked car, the lookout police cruiser, its vigilant driver. Peterson took the Glock out of his holster and checked it over and put it back. Reacher had the Smith & Wesson in his trouser pocket. He didn't need to check it was there. He could feel its weight. his head. Seven o'clock. Five past. Ten past. A quarter past. No activity on the street. The view out from under the lip of the porch stayed the same. Snow, ice, wind, Peterson's parked car, the lookout police cruiser, its vigilant driver. Peterson took the Glock out of his holster and checked it over and put it back. Reacher had the Smith & Wesson in his trouser pocket. He didn't need to check it was there. He could feel its weight.

Peterson was at the window. Reacher sat down, in Janet Salter's chair. He was thinking about the runway, and the old stone building, and the wooden huts.

The first wooden hut, in particular.

He asked, 'Does Kim have a sister?'

Peterson said, 'No.'

'A niece or a cousin?'

'No nieces. Some cousins. Why?'

'That girl I saw in the hut, sitting on the bed. She looked familiar. At first I thought I had seen her before. But I don't see how. So now I'm trying to pin it down. Either she was just a local type, or she looks like someone else I saw.'

'There's no real local type here.'

'You think? You and Chief Holland look the same.'

'He's older.'

'Apart from that.'

'A little, maybe. But there's no local type.'

'Then that girl looked like someone I saw. On my first night here, I think. And the only woman I saw on my first night here was Kim.'

'And the old ladies on the bus.'

'No resemblance.'

'The waitress in the restaurant?'

'Not her.'

'Kim doesn't have sisters. Or nieces. And I think all her cousins are boys.'

'OK,' Reacher said.

'Maybe you saw a guy. Brothers and sisters can look alike. Lowell has a sister who looks just like him. Remember him? The officer you met?'

'Tough on her,' Reacher said.

'What did this mystery girl look like anyway?'
