Almost every officer is going to put their life on the line at some point in their career.

The world is changing and people don't like change.

I never actually wanted to write horror, oddly enough. It was a kind of misnomer, because I didn't ever actually write horror in the sense of the genre known for it. It was more a type of pigeon-holing in bookshops.

If you and I took a walk down a shopping street in Jo'burg or Cape Town or London, we see two guys looking in a shop window, we think, "Oh, they're wondering what they're going to buy." A cop looks at them and thinks, "Why are they standing there? Are they doing a drug deal? Are they going to mug someone? Are they going to rob the shop?"

If you go into a bar or restaurant with a cop, the first thing he does is he'll stand in the entrance, and he'll look at every single face in that room because he doesn't want to spend an hour having a drink or lunch and didn't spot some villain they've been looking for, for two years.

Obviously I don't have whatever it is you need to be a successful writer.

There's a difference between what I call a dumb ghost and a smart ghost. The smart ghost is Hamlet's father - you know, he says, "Get revenge, my son!" That's incredibly rare. It's much more the grey lady in the same place everyday, moving across the floor.
