Neither Commissario Brunetti nor his wife Paola have ever had much sympathy for the Italian armed forces, so when a young cadet is found hanged, a presumed suicide, in Venice's elite military academy, Brunetti's emotions are complex: pity and sorrow for the death of a boy, close in age to his own son, and contempt and irritation for the arrogance and high-handedness of the boy's teachers and fellow-students. But as Brunetti investigates further he is faced by a wall of silence, as the military protects its own and civilians are unwilling to talk. Is this the natural reluctance of Italians to involve themselves with the authorities, or is Brunetti facing a conspiracy of silence?
