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.

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

Life's not some slot machine in an arcade with a sign that flashes up saying 'I'm sorry, you have been killed. Would you like another go?' But we might get put through the same test each time, get faced with the same situations until we've learned how to cope.

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.

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.

Every profession has its own culture, but the police look at the world differently to everybody else. I call it a 'healthy culture of suspicion'.

Police do get obsessed with solving crimes. You know, particularly if there's been a murder, it becomes personal for the police officer very quickly, and it gets to the family. Even after they've retired, they carry on, not letting go.
