‘I’m naturally contrary.’

‘Did you finish your reading?’

‘Not yet.’

‘We checked for financial irregularities,’ Christopher said. ‘Or financial excesses, I suppose. But they’re all living within their means. Appropriate accommodations, four-cylinder cars, good clothes but small wardrobes, modest jewellery, no vacations, not that they’d take a vacation anyway. Not fast track people. Not if they want to be Chief of Staff one day. Or a defence industry lobbyist.’

Reacher put the thirty-year-old Lieutenant Colonel Christine Richardson to the bottom of the pile, and started in on the second of the women, twenty-nine years old and a mere major, name of Briony Walker, the daughter of a retired naval officer, brought up mostly in Seattle and San Diego, public elementary school, public high school, valedictorian, West Point.

Christopher said, ‘I hope it’s not her.’

Reacher said, ‘Why?’

‘The naval connection.’

‘You like the navy?’

‘Not much, but it’s still a military family.’

The third candidate was another thirty-year-old light colonel, this one called Darwen DeWitt, and right there Reacher knew she wasn’t the product of a military family. Not with a name like that. In fact she was the daughter of a Houston businessman who owned about a hundred dent-repair franchises. Private education all the way, softball star, West Point.

The fourth was Alice Vaz, age thirty, lieutenant colonel, granddaughter of another lieutenant colonel, except this one had been called Mikhail Vasilyevich and he had been a lieutenant colonel in the Red Army. A Soviet. His son, Alice’s father, had gotten out of Hungary just in time, with a pregnant wife, and Alice had been born in the United States. A citizen. California, public elementary, public high, West Point.

‘Notice anything definitive?’ Christopher asked.

Reacher said, ‘Their names are perfectly alphabetical. Alice, Briony, Christine and Darwen.’
