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.

There are an awful lot of readers who won't pick up a book if they think it's got anything horrific in it, or paranormal or whatever.

A news junkie, I read, daily, the 'Times/Sunday Times,' the 'Guardian/Observer,' 'Mail,' and the 'Argus' - both to keep up with crime in Brighton, where I set my novels, and because I think it is vital to support local papers - they provide a unique accountability for councils, emergency services and so much else, and are dangerously undervalued.

What Brighton's got is a major sea port on either side, good for importing drugs, great for exporting cash, stolen cars, stolen antiques. It's got the largest number of antique shops in the UK, so it's a great place to fence stolen goods. It's got tremendous communication: you've got the sea ports, you've got the channel tunnel, you've got Gatwick Airport 25 minutes away, and London's 50 minutes away by train. So all these escape routes... Which is what villains like.

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?"

The crime genre's always been regarded very well by the literary end of the book world, whereas horror, although it had that spell in the late eighties, by and large, it's sort of ghetto-ized, and considered to be exploited literature.

There are people who can achieve huge success in life, while adding a bit of fun and a splash of colour to this increasingly grey world.
