Not knowing the story or excerpt you are referring to, I can only help you by asking some questions to get you thinking about the correct answer. Is the village far away from other villages or towns? Are there many sick people in the village making the doctor want to stay away? Is there a lot of violence that the doctor is trying to avoid?
