You Want an Anti-Hero?

I got yer anti-hero right here: Roger Brown, protagonist of Jo Nesbo's Headhunters. Other mystery writers may claim that they like writing flawed characters, but this usually means a middle-aged guy with a paunch and a drinking problem, a grown daughter he's estranged from because his police work makes him late to all their get-togethers, an ex-wife that he disappointed one too many times. You haven't seen flawed till you've met Roger Brown.
