“And some go the other way, the most lethal way of all: when the pressure gets to be too much, it's not their nerve that breaks, it's their fear. They lose the capacity to be afraid, even when they should be. These can't ever go home again. They're like those First World War airmen, the finest ones, shining in their recklessness and invincible, who got home and found that home had no place for what they were. Some people are undercovers all the way to the bone; the job has taken them whole.”

“For one last second, I saw them again the way I had that evening: a golden apparition on the front steps, shining and poised like young warriors stepped out of some lost myth, heads lifted, too bright to be real.”

“Our entire society is based on discontent. People wanting more and more and more. Being constantly dissatisfied with their homes, their bodies, their décor, their clothes, everything – taking it for granted that that’s the whole point of life. Never to be satisfied. If you are perfectly happy with what you got, especially if what you got isn’t even all that spectacular then you’re dangerous. You’re breaking all the rules. You’re undermining the sacred economy. You’re challenging every assumption that society is built on.”

“There was a time when I believed I was the redeemed one, the boy borne safely home on the ebb of whatever freak tide carried Peter and Jamie away. Not any more. In ways too dark and crucial to be called metaphorical, I never left that wood.”

“And God the taste of undercover on my tongue again, the brush of it down the little hairs on my arms. I'd thought I remembered what it was like, every detail, but I'd been wrong: memories are nothing, soft as gauze against the ruthless razor-fineness of that edge, beautiful and lethal, one tiny slip and it'll slice to the bone.”

“I was never afraid of getting killed and I was never afraid of losing my nerve. My kind of courage holds up best under fire; it's different dangers, more refined and insidious ones, that shake me.”

“I know what the right woman, at the right moment, can do to a man- not that Tessie seemed to have got away scot-free herself. Some people should never meet. The fallout spreads too wide and gets into the ground for much too long.”
