Saevus Corax Deals With the Dead by K. J. Parker

From one of the most original voices in fantasy comes a twisted tale of murder, betrayal, and battlefield salvage. 

There’s no formal training for battlefield salvage. You just have to pick things up as you go along. Swords, armour, arrows – and the bodies, of course.
 
Over the years, Saevus Corax has picked up a lot of things. Some of them have made him decent money, others have brought nothing but trouble. But it’s a living, and somebody has to deal with the dead.
  
Something else that Saevus has buried is his past. Unfortunately, he didn’t quite succeed.
