Stieg Larsson’s Inspector Monica Figuerola
If you haven’t read Larsson’s Millennium trilogy, fuckin’ get on it. The Girl Who Kicked the Hornet’s Nest has some of the most badass female characters ever, including Figuerola.

"Where do we start?" [Blomkvist] said.
"We could start by having coffee… Monica?" Edklinth said.
"Thanks, that would be nice," Figuerola said. 

That’s probably my favorite quote from this book.
