It's a very, very fascinating story for me, cause it's about a man who's been doing bad; bad things. And he's a father of four children in parochial school, he's a lieutenant of detectives, but he's in conflict with himself and with trying to do what's right.
Perseverance is not a long race; it is many short races one after the other.
I enjoy pushing my characters to the limit. No matter how far out there I go, I look for things that make the characters human.
