My work schedule has changed over the years. The one constant is, when at work on a novel, I try to work seven days a week, so as not to lose touch with that world. Within that, I'm flexible on hours and output.

There are a couple of writers I admired who were very good at giving the character's emotion without stating what that emotion was. Not saying "He was feeling tense," instead saying, "His hand squeezed harder on the chair arm," as if staying outside the guy. I wanted to try doing that. I wanted to have a really emotional story in which the characters' emotions are never straight - out told to you, but you get it.

I was writing everything. I grew up in Albany, New York, and I was never any farther west than Syracuse, and I wrote Westerns. I wrote tiny little slices of life, sent them off to The Sewanee Review, and they always sent them back. For the first 10 years I was published, I'd say, "I'm a writer disguised as a mystery writer." But then I look back, and well, maybe I'm a mystery writer. You tend to go where you're liked, so when the mysteries were being published, I did more of them.

For a long while, I found Parker impossible. He went away for 23 years. I tried to bring him back a few times, and I sort of figured out where he came from, why he went away, and why he came back. The thing that I have to tap into for Parker is in some way the outsider. If I can tap into the outsider, I can write about Parker, and if I can't, I can't.

I don't think I would have been a good architect. Really, I have thought about this from time to time, and I might have wound up like my father, who never did find that which he could devote his life to. He sort of drifted from job to job. He was a traveling salesman, he was a bookkeeper, he was an office manager, he was here, there, there. And however enthusiastic he was at the beginning, his job would bore him. If I hadn't had the writing, I think I might have replicated what he was doing, which would not have been good.

I know people who have suffered writer's block, and I don't think I've ever had it. A friend of mine, for three years he couldn't write. And he said that he thought of stories and he knew the stories, could see the stories completely, but he could never find the door. Somehow that first sentence was never there. And without the door, he couldn't do the story. I've never experienced that. But it's a chilling thought.

I don't think I ever have trouble with writer's block. It's different when you make it up as you go - that means you're going to get stuck. I wouldn't call it writer's block, I'd say, "I don't know where the hell this story is going."
