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 read a lot. I always have, but in those two years I gorged myself on books with a voluptuous, almost erotic gluttony. I would go to the local library and take out as many as I could, and then lock myself in the bedsit and read solidly for a week. I went for old books, the older the better - Tolstoy, Poe, Jacobean tragedies, a dusty translation of Laclos - so that when I finally resurfaced, blinking and dazzled, it took me days to stop thinking in their cool, polished, crystalline rhythms.

When we can't see a pattern, we fit pieces together until one takes shape, because we have to.

With acting, you have to depend on somebody else to decide if you are allowed to work. You can spend weeks and months when you are not acting at all.

Now death is uncool, old-fashioned. To my mind the defining characteristic of our era is spin, everything tailored to vanishing point by market research, brands and bands manufactured to precise specifications; we are so used to things transmuting into whatever we would like them to be that it comes as a profound outrage to encounter death, stubbornly unspinnable, only and immutably itself.

Regardless of the advertising campaigns may tell us, we can't have it all. Sacrifice is not an option, or an anachronism; it's a fact of life. We all cut off our own limbs to burn on some altar. The crucial thing is to choose an altar that's worth it and a limb you can accept losing. To go consenting to the sacrifice.

I can't explain the alchemy that transmuted one evening into the equivalent of years held lightly in common. The only way I can put it is that we recognized, too surely even for surprise, that we shared the same currency.
