Sometime ago I read a short story set either in Alaska or the northern part of Canada. The protagonists of the story did some kind of work which involved moving supplies with sleds and dogs. They were bullied by their boss, who was a mean drunk. Eventually they get fed up with it and, while he’s away, replace the liquor in his flask with poisonous wood alcohol. He drinks it and dies.
I read this story, I believe, in an English text book from middle school or high school.
Does anyone know what it was?
