Day of the wolf

the long version

"When mysterious mountain man Wolf comes down to the Crow village to return one of its wounded, the Crow wonder whether he is man or spirit. Wanting no part in the rampant war in the western plains, Wolf is set on returning to his mountain refuge. But his journey home is interrupted by three desperate women who need his help. What Wolf doesn't realize about these women is that they aren't what most people would call ladies. His innocent association with these prostitutes leads to a near-deadly fight that ends with a charge for attempted murder. Chased by the most experienced deputy the marshal service has, Wolf leads him to the Black Hills, where their final showdown can only end in blood" -- from publisher's web site.
