Twin Riders by Bob Dowd

Roy and Ray were identical twin brothers. When dressed alike, no one could tell them apart. Until the gunfight started. Roy was untouchable up close. Even though many had said they saw him draw his pistol, in reality, they had not. Ray on the other hand, while not nearly as fast as Roy, could hit a man at an unthinkable distance with his pistol. So, what does that mean to those that crossed paths with the brothers? It meant that if they were up close, and it was Roy they were shooting against---They would die. If they were at any distance and it was Ray they were shooting against---They would die. Many had called one of the brothers out---all had died. Why? Because if the fight was close, Roy would make sure he was the one stepping outside. If it was a distance shoot out, Ray would slip in and replace Roy. They had fooled many people, in many towns, for many years. (They had even been known to replace each other with the young ladies as well, but that's another part of the story). Ha. Their system with gunfighters and young ladies alike was working well for them, until Diana entered the picture. Roy fell in love. It was never the same. This story equates to Deadwood meets Fifty Shades of Grey. This book is rated 'R'.
