been trained directly west to east along the road right above where the yellow line was buried under the snow. It was a featureless picture. Nothing to see. Passing tyres had dug trenches, the base of the ruts had been crushed downward, small side walls had been thrown upward, tiny avalanches had fallen outward from the top of the side walls, and those small fallen fragments had been smoothed over by a crust of fresh snow.
    Nothing else.
    ‘Good pictures,’ Reacher said.
    ‘I did my best,’ Peterson said.
    ‘Fine work.’
    ‘Thank you.’
    ‘No footprints,’ Reacher said.
    ‘Agreed,’ Peterson said.
    The fourth photograph was a close-up of one of the eastbound ruts. Nothing to see there either, except broken and confused pieces of tread marks, the same small waffles and lattices Reacher had seen all over town. No way to reconstruct anything worth sending to a lab.
    The fifth picture was a close-up of the car, taken from the front right side. It was a small neat sedan, a make Reacher didn’t recognize.
    ‘Infiniti,’ Peterson said. ‘It’s Japanese. Nissan’s luxury division. That model has a V-6 engine and full-time four-wheel drive. There are snow tyres on it, all around. It’s practical, and it’s about as showy as a South Dakota lawyer wants to get.’
    It was painted a light silver colour. It was basically clean, but grimed over by several recent winter trips. The way the light reflected off the snow and played over the paint made it look ghostly and insubstantial. The driver’s window was all the way open. The dead guy was pinned upright against the seat back by the belt. Some snow had blown in on him. His chin was on his chest. He could have been asleep, except for the hole in his head.
    The hole was the subject of photograph number five. It was in the centre of the guy’s forehead. Like a third eye. Clearly the guy had been looking out the window, halfway between sideways and straight ahead. He had been shot right down his line of sight. He had been looking at the gun. The exit wound had spattered stuff all over the window diagonally behind him. His head had then slumped down and rotated back to a central position.
    The rest of the photographs were of the body and the interior of the vehicle from every conceivable angle.
Take plenty of photographs
, Reacher had said, and Peterson had complied to the letter. There was a pair of rubber overshoes neatly placed in the passenger foot well. There was a small multi-purposechrome hammer mounted centrally on the dash. Reacher had seen them advertised in mail order brochures on aeroplanes. They could tap the windshield out if the doors were jammed after a wreck. They had a blade concealed in the handle to cut seat belts. Ideal accessories for cautious, meticulous, organized people interested in cars. But Reacher wondered whether one had actually ever been used in earnest in the whole history of automotive transport. He suspected not.
    The Infiniti’s shifter was in Park. Its ignition key was turned to the run position. The tachometer showed an 800-rpm idle. The odometer showed fewer than ten thousand miles. Cabin temperature was set at sixty-nine degrees. The radio was tuned to a local AM station. The tick on the volume knob was all the way over at the eight o’clock position. Turned down low. The gas dial showed the tank to be close to full.
    Reacher said, ‘Tell me the story.’
    Peterson said, ‘OK, Knox is in a vehicle. He’s driving. He’s heading east. The lawyer is heading west. They’re both driving slow, because the road is bad. Knox sees the lawyer coming. He winds his window down. Puts his arm out and flags the lawyer down. The lawyer slows and stops. He winds his own window down. Maybe he thinks that Knox is going to warn him about a danger up ahead. Driver to driver, like people do in adverse conditions. Instead, Knox shoots him and drives on.’
    ‘Who found the body?’
    ‘Another guy heading east. Maybe five or ten minutes after it happened. He slowed, took a look, and called us from a gas station two miles farther on. No cell phone.’
    ‘Is Knox right-handed?’
    ‘I don’t know. But most people are.’
    ‘Did you find a shell case?’
    ‘No.’
    ‘If Knox is right-handed, then he was shooting diagonally across his body. He would want reasonable arm extension. The muzzle was probably out the window, just a little. The ejection port on a Glock is on the right side of the gun. So he had to be very careful with his
