The Sisters brothers

"Hermann Kermit Warm is going to die. The enigmatic and powerful man known only as the Commodore has ordered it, and his henchmen, Eli and Charlie Sisters, will make sure of it. Though Eli doesn't share his brother's appetite for whiskey and killing, he's never known anything else. But their prey isn't an easy mark, and on the road from Oregon City to Warm's gold-mining claim outside Sacramento, Eli begins to question what he does for a living-and whom he does it for."-- Publisher description.
