I think that the way that I write stories is by instinct. You have some basic ideas - a character, or an image, or a situation that sounds compelling - and then you just feel your way around until you find the edges of your story. It's like going into a dark room... you stumble around until you find the walls and then inch your way to the light switch.

I can't understand how people can settle for having just one life. I remember we were in English class and we were talking about that poem by - that one guy. David Frost. 'Two roads diverged in a yellow wood-' You know this poem, right? 'Two roads diverged in a yellow wood, and sorry I could not travel both and be one traveler, long I stood and looked down one as far as I could, to where it bent in the undergrowth-" "I loved that poem. But I remember thinking to myself: Why? How come you can't travel both? That seemed really unfair to me.

A lot of time, with stories, I'll start out with a title and try to dream myself into the story that it evokes - a kind of subconscious exercise in which I'm trawling for some kind of entryway into fiction.

Fiction is a particular kind of rhetoric, a way of thinking that I think can be useful in your life. It asks you to image the world through someone else's eyes, and it allows you to try to empathize with situations that you haven't actually experienced.

I'm working with fragments a lot of the time and the connective tissue isn't there yet. I think of it the way comics work. You have a block here and a block here, and there's this white space in between. Somehow your mind makes the leap to connect those two blocks. Finding a way to trick your mind into connecting those blocks is one of the fun things for me about writing. You can have those leaps that will emerge into something, if you're lucky.

I've been reading Peter Straub since I was a teenager, and his work is hardwired into my brain. A Dark Matter contains echoes of all that has been great about Straub's previous work and builds upon it. This Rashomon-like tale is as spooky and frightening as anything he has written, but it's also an intense and moving celebration of love. Out of the darkness comes, ultimately, a surprising and haunting sense of joy.

The thing that made me turn more towards writing was realizing how hard it was going to be to get a singular vision on film and how much more control I would have if I were writing novels.
