Twelve witnesses testified against Aristèides Albanese at that time. He spent seventeen years in prison for manslaughter. Now he is out and wants to take revenge on all of them. And in a very special way, as Aristèides is a chef and plans to prepare the execution meal for each of them himself. Commissario Proteo Laurenti was never convinced by the statements of the twelve, yet at that time he did not stand up to the prosecutor, who seemed obsessed with the case, despite knowing better. To this day, Laurenti regrets not having confronted him. Just as Aristèides is back on the streets, there is another corpse, and once again he is among the suspects. As he did seventeen years ago, Laurenti investigates and desperately tries to find the missing link between the cases.
