“Most people are only too delighted to wreck each other's heads. And for the tiny minority who do their pathetic best not to, this world is going to go right ahead and make sure they do it anyway.”

“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.”

“Rule Number Three, and Four and Five and about a dozen more: you do not go with the flow in this job. You make the flow go with you.”

“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.”

“Have you noticed how easily the very young die? They make the best martyrs for any cause, the best soldiers, the best suicides. It's because they're held here so lightly: they haven't yet accumulated loves and responsibilities and commitments and all the things that tie us securely to this world. They can let go of it as easily and simply as lifting a finger. But as you get older, you begin to find things that are worth holding onto, forever.”

“Sarte was right, Hell is other people”

“People need a moral code, to help them make decisions. All this bio-yogurt virtue and financial self-righteousness are just filling the gap in the market. But the problem is that it's all backwards. It's not that you do the right thing and hope it pays off; the morally right thing is by definition the thing that gives the biggest payoff.”
