Widowmaker Jones
(Book)

"With a bag full of gold dust, Newt "Widowmaker" Jones is set for life. Then he makes his first mistake, trusting a cheerful stranger. By dawn the stranger--Javier Cortina, the son of the famous Texas border bandit, Juan "Red" Cortina--is gone. So is the gold. So are Newt's horse and even his fearsome Colt .44. It's enough to make a man want vengeance. And vengeance will be Newt's. Newt chases Cortina into Mexico, where the man is legendary for the horses he's stolen, the women he's bedded, and the men he's killed. As for Newt, he has a unique talent for choosing the wrong partners, from an angry, addled judge named Roy Bean to a brother and sister pair of circus gypsies, Fonzo Grey and Buckshot Annie. The more Newt pursues the cunning and deadly Cortina, the angrier he gets, until somewhere on the border the whole crazy journey explodes into an all-out battle of bullets and blood" --from Amazon.
