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.

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.

We're full of electricity, and the walls and floor of a building contain carbon - the same makeup as a video tape - and I think we give off a huge amount of energy. Some people are able to see that and pick that up. I think almost every person I've met in my life has had some sort of experience that they can't explain, and those fascinate me.

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 like dogs. Dogs don't judge people.

The biggest qualification to be a good police officer is to have a high degree of emotional intelligence.
