I used to be something of an obsessive when it came to research. When I first began writing the Thorne novels, I would drive to a set of traffic lights in the early hours of the morning to make sure you could turn left. I thought it was important to get even the most trivial details right.

Too much research can be the writer's enemy. You can spend days on end in the British Library or prowling the streets with a Dictaphone, and it's easy to convince yourself that you're working hard. Often, it can be an excuse not to work; a classic displacement activity.

It never ceases to amaze me that readers who are willing to suspend their disbelief when it comes to the motivation of a vicious serial killer get high and mighty because I have put a coffee shop where there isn't one. Er... it's a novel. I made one up. I'm allowed to make stuff up. I'd go as far as to suggest that I make stuff up for a living.
