Early in the story, a phone call wakes Norman in the middle of the night while he’s staying in Helena with his brother: Paul and an Indian girl called Mo-nah-se-tah are in jail. Paul hit a man in Weiss’s restaurant for disrespecting her.

A River Runs Through It: Last Chance Gulch (Helena)
She liked to hold Paul with one arm and me with the other and walk down Last Chance Gulch on Saturday night, forcing people into the gutter to get around us, and when they wouldn’t give up the sidewalk she would shove Paul or me into them. You didn’t have to go very far down Last Chance Gulch on Saturday night shoving people into the gutter before you were into a hell of a big fight….
When her hair glistened, though, she was worth it. (25-26)
