The Sisters Brothers by Patrick deWitt
This is a western set during the California Gold Rush. Charles and Eli Sisters are brothers who have quite the reputation. They are killers for hire and they are successful and ruthless.
The story is told from the voice of Eli, the younger brother. He is laying out their life as they go on another job. Relations seem strained between Eli and Charles and Eli is contemplating a new line of work.
This was a "light, fun read" after I finished my failed attempt at Satanic Verses and then reading Wolf Hall.
It wasn't really light but it was darkly humorous and I did enjoy it and the Murphy's Law way that things turned out.
