"He's..." Smithback paused, feeling uncharacteristically at a loss for words. "He's unorthodox. Charming, a southern aristocrat, lots of dough, old family money, pharmaceuticals or something. I don't really know what his relationship is with the FBI. He seems to have free rein to poke into anything he likes. He works alone and he's very, very good. He knows a lot of important people. As far as the man personally, I don't know anything about him. He's a cipher. You never know what he's thinking. Christ, I don't even know his first name."
