He had lost his sense of smell

Kastriot had lost his sense of smell so they made him a cleanup man. Dead rats, rotten fruit, vomit, excrement, nothing bothered him. He was clean and quiet and he never complained. He took any job that others refused and hardly anyone noticed him. The servants of important persons brought him into the palaces where he was ignored by councilors and concubines. He had a good mind for detail and he never forgot anything. He learned everyone’s secrets, and he kept them secret.
