What role can or should loyalty play in the life of a police inspector? It is a question that Commissioner Brunetti must face and ultimately answer in this case when the distinguished Elisabetta Foscarini, a childhood acquaintance, asks him for a favor. Elisabetta's mother was always generous with her family, so Brunetti feels obliged to help her and starts a private investigation to try to find out who could be threatening her daughter's family. However, so far there is little concrete evidence: why would they want to harm a veterinarian and an accountant who works for a charity? The commissario is about to let the matter drop, attributing it to exaggerated maternal concern, when an attack occurs and the case takes a very dark turn. Brunetti will be forced to call in his own favors to move forward with an investigation that will inevitably become official when he discovers the two faces of what seemed like a venerable institution.
