"True Grit" by Charles Portis, in which the narrator, 14 year-old Mattie Ross, is looking to recruit a Federal marshal to pursue the man who killed her father:
"Who is the best marshal they have?"
The sheriff thought on it for a minute. He said, "I would have to weigh that proposition. There is near about two hundred of them. I reckon William Waters is the best tracker. He is half-breed Comanche and it is something to see, watching him cut for sign. The meanest one is Rooster Cogburn. He is a pitiless man, double-tough, and fear don't enter into his thinking. He loves to pull a cork. Now, L. T. Quinn, he brings his prisoners in alive. He may let one get by now and then but he believes even the worst of men is entitled to a fair shake. Also the court does not pay any fees for dead men. Quinn is also a good peace officer and a lay preacher to boot. He will not plant evidence or abuse a prisoner. He is straight as a string. Yes, I will say Quinn is about the best they have."
I said, "Where can I find this Rooster?"
I'd explain everything that's right about this for you, but I am pretty sure it's self-explanatory.
