The thing about being a mystery writer, what marks a mystery writer out from a chick lit author or historical fiction writer, is that you always find a mystery in every situation.

I hate nostalgia, it's laziness with prettier accessories.

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.

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

People you knew when you were teenagers, the ones who saw your stupidest haircut and the most embarrassing things you've done in your life, and they still cared about you after all that: they're not replaceable, you know?

I listen to the things people want out of love these days and they blow my mind. I go to the pub with the boys from the squad and listen while they explain, with minute precision, exactly what shape a woman should be, what bits she should shave how, what acts she should perform on which date and what she should always or never do or say or want; I eavesdrop on women in cafes while they reel off lists of which jobs a man is allowed, which cars, which labels, which flowers and restaurants and gemstones get the stamp of approval, and I want to shout, Are you people out of your tiny minds?

Over time, the ghosts of things that happened start to turn distant; once they've cut you a couple of million times, their edges blunt on your scar tissue, they wear thin. The ones that slice like razors forever are the ghosts of things that never got the chance to happen.
