The girls I dream of are the gentle ones, wistful by high windows or singing sweet old songs at a piano, long hair drifting, tender as apple blossom. But a girl who goes into battle beside you and keeps your back is a different thing, a thing to make you shiver. Think of the first time you slept with someone, or the first time you fell in love: that blinding explosion that left you cracking to the fingertips with electricity, initiated and transformed. I tell you that was nothing, nothing at all, beside the power of putting your lives, simply and daily, into each other's hands.

I’m the least fanciful guy around, but on nights when I wonder whether there was any point to my day, I think about this: the first thing we ever did, when we started turning into humans, was draw a line across the cave door and say: Wild stays out. What I do is what the first men did. They built walls to keep back the sea. They fought the wolves for the hearth fire.

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.

You’re challenging every assumption that society is built on.

This is the one thing I hope: that she never stopped. I hope when her body couldn't run any farther she left it behind like everything else that tried to hold her down, she floored the pedal and she went like wildfire, streamed down night freeways with both hands off the wheel and her head back screaming to the sky like a lynx, white lines and green lights whipping away into the dark, her tires inches off the ground and freedom crashing up her spine.

What I warn you to remember is that I am a detective. Our relationship with truth is fundamental but cracked, refracting confusingly like fragmented glass. It is the core of our careers, the endgame of every move we make, and we pursue it with strategies painstakingly constructed of lies and concealment and every variation on deception.

Here's a little tip for you. If you don't like being called a murderer, don't kill people.

Sometimes, when you're close to someone, you miss things. Other people can see them, but you can't.
