Peterson said nothing more, and a minute later dinner arrived. Plates piled high, mashed potatoes, plenty of gravy. The coffee was an hour old, and it had suffered in terms of taste but gained in terms of strength.

Peterson asked, ‘What exactly did you do in the MPs?’

Reacher said, ‘Whatever they told me to.’

‘Serious crimes?’

‘Sometimes.’

‘Homicides?’

‘Everything from attempted to multiple.’

‘How much medical training did you get?’

‘Worried about the food here?’

‘I like to know things too.’

‘I didn’t get much medical training, really. I was trying to make the old folks feel better, that’s all.’

‘They spoke well of you.’

‘Don’t trust them. They don’t know me.’

Peterson didn’t reply.

Reacher asked, ‘Where was the dead guy found? Where the police car was blocking the side street?’

‘No. That was different. The dead guy was somewhere else.’

‘He wasn’t killed there.’

‘How do you know?’

‘No blood in the snow. Hit someone hard enough in the head to kill them, the scalp splits. It’s inevitable. And scalps bleed like crazy. There should have been a pool of blood a yard across.’

Peterson ate in silence for a minute. Then he asked: ‘Where do you live?’

Which was a difficult question. Not for Reacher himself. There was a simple answer. He lived nowhere, and always had. He had been born the son of a serving military officer, in a Berlin infirmary, and since the day he had been carried out of it swaddled in blankets he had been dragged all over the world, through an endless blur of military bases and cheap off-post accommodations, and then he had joined up himself and lived the same way on his own account. Four years at West Point was his longest period of residential stability, and he had enjoyed neither West Point nor stability. Now that he was out of the service, he continued the transience. It was all he knew and it was a habit he couldn’t break.
