If you talk to any cop, however hardened, and say, "Has anything that's ever bothered you", they'll tell you about the death of a child that they had to deal with.

There's a really classic cliche every time you switch the TV on - you see cops arguing. I have spent a day a week for many years in the presence of police and I have never seen them argue. It's a military hierarchy. They do what they're told. There's no bickering.

Brighton has two universities. It's got a massive young, middle-class community, and the largest gay community in the UK. The result of which is a huge recreational drug market. It's the favoured place to live in the UK for first division criminals.

There's no question that ghosts exist. The big question for me is whether ghosts are simply electronic imprints left in the walls or the atmosphere of places, or whether they do actually represent something from the afterlife.

My day starts with Radio 4's Today live or 'listen again' wherever I am in the world, thanks to digital radio - I even have an app on my iPhone that receives it.

I think the police are a major part of the glue that holds civilised life together. They're not highly paid.

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.
