The smell of the sea swept over the wall and in through the empty window-hole, wide and wild with a million intoxicating secrets. I don't trust that smell. It hooks us somewhere deeper than reason or civilization, in the fragments of our cells that rocked in oceans before we had minds, and it pulls till we follow mindlessly as rutting animals....It lures us to leap off high cliffs, fling ourselves on towering waves, leaves behind everyone we love and face into thousands of miles of open water for the sake of what might be on the far shore.

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.

I used to think I sewed us together at the edges with my own hands, pulled the stitches tight and I could unpick them any time I wanted. Now I think it always ran deeper than that and farther, underground; out of sight and way beyond my control.

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.

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.

I am not good at noticing when I'm happy, except in retrospect. My gift, or fatal flaw, is for nostalgia. I have sometimes been accused of demanding perfection, of rejecting heart's desires as soon as I get close enough that the mysterious impressionistic gloss disperses into plain solid dots, but the truth is less simplistic than that. I know very well that perfection is made up of frayed, off-struck mundanities. I suppose you could say my real weakness is a kind of long-sightedness: usually it is only at a distance, and much too late, that I can see the pattern.

One of my da's tragedies was always the fact that he was bright enough to understand just how comprehensively he had shat all over his life.
