What happened with the opioid epidemic is the Mexican cartels made a very deliberate, corporate decision to undercut the price of opioids. What they discovered was they could increase production, increase potency and decrease the price, and sell it for a third of what the Big Pharma could, or street dealers could, for Big Pharma pills. North America, and to a slightly lesser extent Europe, is being flooded with this Mexican heroin as a direct result of the attempt to undercut American pharmaceutical companies.

The Americans take a product that literally grows on trees and turn it into a valuable commodity. Without them, cocaine and marijuana would be like oranges, and instead of making billions smuggling it, I’d be making pennies doing stoop labor in some California field, picking it.

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.

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 have a life, I have a wife. I have an adult son who I'm very close to, and friends. I go hiking almost every day, four to six miles. In the summer, I'm out surfing or swimming. I think that real, human relationships with people mostly balance dark places in my work.

I start work at 5 in the morning and I have a wicked insomnia problem.
