Inspector Montalbano must search for his missing right-hand man, but is he already too late? Before leaving for vacation with Livia, Montalbano witnesses a seagull doing an odd dance on the beach outside his home, when the bird suddenly drops dead. Stopping in at his office for a quick check before heading off, he notices that Fazio is nowhere to be found and soon learns that he was last seen on the docks, secretly working on a case. Montalbano sets out to find him and discovers that the seagull’s dance of death may provide the key to understanding a macabre world of sadism, extortion, and murder.
