You know, people call mystery novels or thrillers 'puzzles.' I never understood that, because when I buy a puzzle, I already know what it is. It's on the box. And even if I don't, if it's a 5,000-piece puzzle of the 'Mona Lisa', it's not like I put the last piece in and go, 'I had no idea it's the 'Mona Lisa'!'

A trial is two narratives competing for your attention.

I don't find any real rivalries with crime and thriller writers anyway. That might sound a little Pollyanna, but for the most part the writers I compete with, if you want to use that word, it's a pretty friendly rivalry. I think we all realise that the boat rises and sinks together.

I remember one time I heard this English professor asking the class what the world's scariest noise is. Is it a man crying out in pain? A woman's scream of terror? A gunshot? A baby crying? And the professor shakes his head and says, 'No, the scariest noise is, you're all alone in your dark house, you know you're all alone, you know that there is no chance anyone else is home or within miles—and then, suddenly, from upstairs, you hear the toilet flush.

Painful memories didn't just ease back in-they shoved the door open hard, all of them and all at once

No characters in 'Stay Close,' including the leads, are black and white. I want them to be grey. I think that makes for a much more interesting reading experience, something that will stay with you a little bit longer.

Hope is cruel. Hope reminds me of what almost was. Hope makes the physical ache return.
