Cambridge is heaven, I am convinced it is the nicest place in the world to live. As you walk round, most people look incredibly bright, as if they are probably off to win a Nobel prize.
I want my books to explore motives which make people think, 'Wow! Imagine the psychological state you'd have to be in for that to be your motive!' Whereas things like blackmail, jealousy - they're rational reasons for committing murder.
I always notice the dysfunctional dynamic of human relationships because most places where you encounter it, people are trying to pretend it isnt happening.
If you ask people if they enjoy crime novels, they'll say, 'Oh, my guilty pleasure is...' then name a really brilliant crime writer.
There are very few well-adjusted people in my books. But I do think that's normal. Because everyone does have their issues and hang-ups.
The crimes in my books are committed by people who can't keep it together any more. They do something to express their own pain, and that has a terrible effect on somebody else.
Weak people always attack strong people - it's safer. It's weak people who are dangerous, who lash out uncontrollably and hurt you back. Stong people can walk away - no repercussions, you see, if you attack a stong person.
