I think people will be surprised at some of the things about the shootings by policemen of unarmed African-American men. But I also think it's a balanced view. Balance has become almost a dirty word these days. It seems we're supposed to pick one side or the other. But these issues are extremely complicated. I think people will be surprised at some of that.

The devil's in the details. The way I view my job is to bring the reader into a world they otherwise could not enter and let them see it through the character's eyes. And you can only do that with detail. The details make the characters distinct from one another. If you can give them those little grace notes, those little touches, that's what makes the reader relate.

Bookstores never seem to know where to put me on the shelves. But I do. I love my genre and I love those writers, so I am happy to be considered a crime writer. That's what I consider myself.

I've been writing since I was six years old. It's hard to imagine stopping. I would hate to think that I've already written my best book.

American cops didn't create that atmosphere, they're the ones though who have to live with it on a daily basis. These are generalisations; you can't make generalisations about hundreds of thousands of people. The New York Police Department, for instance, has 38,000 police officers in it. But most cops, when I talk to them, desperately care about the victims of gun violence. They see it, they experience it.

I try to pay attention to language. I think that as a general rule, we as writers talk too much and we should listen more. I read my dialogue out loud to myself because I think that's when you catch the wrong notes and the wrong tones.

The Force deals a lot with the heroin epidemic, which I'm sorry to know people are experiencing in Canada.
