There was only one female marshal in the Indian Nations under Judge Issac Parker...Deputy US Marshal F.M. Miller. She teams up with Bass Reeves in Bass and the Lady and goes undercover to stop a new gang of murdering rustlers. Bass has an arrest warrant for his own son...for murder. Fiona Miller is also after the killer of her husband...but she's not a vigilante, she has to bring him in legally. It's why she became a Federal Officer. "It doesn't matter whether I stand or squat to pee...I'm wearing a Deputy United States Marshal's badge...and that trumps just about everything else I know..." Can she go toe to toe with the invincible legendary Bass Reeves? Can Bass keep up with the indomitable Fiona May Miller? Do the outlaws stand a chance against the two of them?
