But, for the role of Sarah Linden, we saw everybody. Everybody wanted this role. Every female actor in town really wanted to play a real woman and be in this drama. It was incredible that all these women were coming in. And then, Mireille [Enos] walked in the door and she was reading the lines that I had written, and I saw her in that field. I was like, "Wow, she's the one."

Seattle is beautiful. You look at the sky and it's one of the most beautiful skies in the world, and then there's the Puget Sound, which will kill you, if you fall into it, but it's also beautiful. Seattle is a city of contradictions. It's the most liberal and most literate city in America, and it has Starbucks and [Bill] Gates, but it's also where the Green River killer hunted women and where the runaway population is just shocking when you walk the streets. Within the same city, there's darkness and light.

I heard John Wells say something really smart, many years ago. He said, "Assume your audience is really intelligent. Assume that they are really smart, and tell your story that way." So, for me, it's about never assuming that they will go away because they're not entertained.

I think it is the hardest thing in the world. I'm endlessly intrigued by what human nature is capable of, both the horrible things we are capable of and also the heroic things. I'm really interested in exploring that side of human nature.

Before I write anything, before I create any assumption in my mind about what it's like to be in that world, I go out there first. I'm very drawn to darkness and light, very drawn to cop drama, because there are very few places besides war and murder and a homicide investigation where you see the extremes of human nature - the darkest crevices and cracks in what people do to one another.

It's a challenge, for sure. My family is not seeing me at all, for probably the next six months, and they haven't seen me for the last year. I'm really blessed with a lot of great partners, including my writing staff. Being able to rely on the people around me has really helped out.

Creating a world that reflects the inner voyage of our characters was really important. Also, because this isn't a black and white show, and this isn't about bad guys and good guys, but it's about good men being capable of bad things and vice versa, I wanted to be in a city that had contradiction.
