Death in a Strange Country

by Donna Leon

Second book in the Guido Burnetti series. Brunetti is a commissario (detective superintendent) in the Italian State Police, stationed in Venice and a native of that city. From Wikipedia: "Early one morning Brunetti is confronted with the body of a young man fished out of a fetid canal. All clues point to a mugging, but robbery seems too convenient a motive. Then something incriminating is found in the dead man's flat, which points to the existence of a high level cabal, and Brunetti becomes convinced that somebody is taking great pains to provide an easy solution to the crime."
