How does Millhone describe her tendency to break rules in the novel, O Is for Outlaw?

From the text:

I was split down the middle, my good angel sitting on one shoulder, Lucifer perched on the other. Duffy's struggle was the same, and while he leaned in one direction, I usually leaned in the other, searching for justice in the heart of anarchy. This was the bottom line as far as I was concerned: If the bad guys don't play by the rules, why should the good guys have to?
