Rim o’ the World 

The Black Rim area in Idaho is a rather rough place, but no where is it more rough than at the Devil’s Tooth Ranch, a ranch run by the Lorrigans. No one willingly messes with the Lorrigans. Tom Lorrigan, the senior of the clan, has three son’s, Al, Duke, and Lance. His spouse, Belle, was at one time an entertainer of some note back East, Belle Delavan, "The Girl with a Thousand Songs".
