‘Will do, ma’am.’

‘Out,’ Sorenson said. She hung up the microphone. She said, ‘How do you stop a car doing a hundred miles an hour? We’ll probably get Puller killed.’

‘In which case we’ll be helping the gene pool.’ Reacher hurtled onward. Dawson and Mitchell were now three hundred yards back. About six seconds, at a hundred miles an hour. But they were still gaining. Reacher scanned far ahead. Straight road, flat dirt, low horizon. No sign of Puller.

He asked, ‘Did your tech team call?’

Sorenson said, ‘Not yet. What’s on your mind?’

‘Motive,’ Reacher said. ‘Who snatches a dead woman’s kid? Especially a kid who saw nothing and knows nothing?’

‘How can the autopsy answer that question?’

‘It might not,’ Reacher said. ‘That’s what’s on my mind.’ His foot was hard on the boards. It was crushing the pedal. But the car was tapped out. It wouldn’t go any faster. A hundred was as good as it got. They passed a turn to the left. Another, on the right. Paved, but not much more than tracks between fields.

‘There,’ Sorenson said.

Reacher saw a dot on the horizon. A tiny smudge, vaguely black and white and gold against the brown. Puller’s cruiser, waiting on the shoulder. Maybe a mile away. Thirty-six seconds. No more turns before it. Far away to the right was a copse of trees. Faraway to the left was an old barn, swaybacked and grey with age.

Thirty seconds.

Twenty seconds.

‘Hold tight,’ Reacher said.

Fifteen seconds.

He clamped the wheel tight in his hands and came off the gas and stamped on the brakes. The front end dipped radically and he and Sorenson were thrown forward and he fought to keep the car straight. Dawson and Mitchell didn’t slow down. They kept on coming. Puller’s car was a hundred yards ahead. Then fifty. Then thirty. Then Reacher swung the wheel hard and drove off the road into the dirt on the right and Dawson and Mitchell were launched ahead of him like a slingshot. Reacher hugged a tight bouncing circle in the dirt and saw Dawson and Mitchell passing Puller at about seventy and Puller lighting up his strobes and his siren and pulling out behind them. Reacher continued the circular turn and thumped back up on the road and headed south, fast, back the way he had come, all the way to the turn he had seen on the left, which was now on the right. He braked hard and took it and pattered over the lumpy surface and turned in on a rutted track and came to a dead stop behind the old swaybacked barn. He got out and ran to the far corner of the ramshackle structure and peered out north.

Nothing in the distance. No sign of Dawson and Mitchell. Not yet. They were still out of sight, more than a mile to the north. He counted out time and space in his head. Right then they would be slowing, stopping, turning around, hassling with Puller, showing ID, arguing, yelling, getting frustrated.

Getting delayed.

Then they would be coming back south, as fast as they could. They would have seen his tight turn on the dirt, and they would be planning on chasing him all the way back to town.

Three minutes, he figured.

Maybe three minutes and ten seconds.

He waited.

And then he saw them, right on time, far away on the main drag, hustling left to right, north to south, doing about a hundred again. An impressive sight. The big stately sedan was really picking up its skirts. Its paint was winking in the watery sun. It was planted firmly on the blacktop, squatting at the rear, straddling the centre line. Reacher ran back past Goodman’s car and peered out from the barn’s other corner. He got a rear view of the blue Crown Vic blasting south. After ten seconds it was a tiny dot. After twenty seconds it was gone altogether.

He breathed out and walked back to the car. He got back in and closed the door. He sat slumped in the seat with his hands on his knees.

Silence. Nothing but the faithful idle of the engine, and clicks and ticks as stressed components cooled back down.

Sorenson said, ‘You’re not such a terrible driver.’

He said, ‘Thank you.’

‘What now?’

‘We wait.’

‘Where?’

‘I guess this place is as good as any.’

She unzipped her black leather bag and took out Goodman’s phone. She clipped it in its dashboard cradle. It chimed once to tell them it was charging.

Then it started to ring.

She leaned over and checked the window.

‘My tech team,’ she said.

FIFTY-THREE

SORENSON TOUCHED THE green button and Reacher heard telephone sounds over the speakers again, weirdly clear and detailed, like before. Sorenson said, ‘You have something for me?’

A man’s voice said, ‘Yeah, we have some preliminary results.’

The voice was tired, and a little breathless. Reacher thought the guy was walking and talking at the same time. Probably stumbling out to the fresh air and the bright sunlight, after long and unpleasant hours in a white-tiled basement room. Breathing deep, blinking, yawning and stretching. Reacher could picture the scene. A pair of institutional doors, a short flight of concrete steps, a parking lot. Maybe planters and benches. Back in the day the guy would have been pausing at that point, to light a welcome cigarette.

Sorenson said, ‘Go ahead.’

The guy said, ‘You want me to be honest?’

‘You usually are.’

‘Then I can’t promise you the incineration was post mortem. It might have been. Or it might not have been. There’s something that might have been damage to what might have been a rib. If I squint a bit I could see it as a gunshot wound to the chest. Which might have been enough. It’s in what would have been the general area of the heart. But I wouldn’t say so in court. The other side would laugh me out of the room. There’s far too much heat damage for conclusions about external injuries.’

‘Gut feeling?’

‘Right now my gut feeling is I want to retrain as a hairdresser. This thing was about the worst I’ve ever seen.’

Sorenson was quiet for a long moment.

Then she said, ‘Anything else?’

‘I started from the beginning, with the pelvic girdle. That’s the only way to confirm gender with a case like this. And it was totally clear. The pelvic bones had been reasonably well protected by a thick layer of fat.’

Reacher looked up. Delfuenso wasn’t fat. She was thin.

Sorenson said, ‘And?’

‘It’s beyond a reasonable doubt the corpse was male.’

Sorenson ran through the details with her guy. Like a crash course in forensic anthropology. Reacher remembered some of the words and some of the principles from the classroom. He had studied such things once, partly as a professional requirement, and partly out of interest. There were four things to look for with pelvises. First was the iliac spread. The ilia were the big bones shaped like butterfly wings, and female ilia were flared wider, and shaped more like a cradle, like cupped hands, with the anterior spines farther apart, whereas male ilia were narrower and tighter and much more straight up and down, more like a guy on a riverbank describing a foot-long trout.

Then second, the hole in the ischium was small and triangular in females, and large and round in males. And third, the angle across the pubic arch was always greater than ninety degrees in females, and rounded, and always less than ninety degrees in males, and sharp.

And the fourth was the clincher, of course: the space between the ischia was big enough in females for a baby’s head to fit through. Not so with males. Not even close.

Pelvises didn’t lie. They couldn’t be confused one for the other. Even a million-year-old pelvis dug out of the ground in pieces was quite clearly either male or female. Short of being ground to powder, a pelvis determined gender, no question, no doubt at all, end of story, thank you and goodnight. That was what Reacher had learned in the classroom, and that was what the voice on the phone confirmed.
