Il metodo Fenoglio - L'estate fredda

Lopez, through photo recognition, indicates and describes in detail 42 individuals belonging to Grimaldi's organization who are arrested. At the port, however, the Carabinieri stop a large incoming shipment but Grimaldi manages to escape and become a fugitive. In the meantime, PM D'Angelo wants to clarify, after several years, the death of her brother Filippo, convinced that he did not die of an overdose, the case of which had been closed in a hurry by Judge Castellaneta under pressure from Marco Lorusso's uncle, a brilliant lawyer who is about to run for mayor and whom she has started seeing again. Thanks to Fenoglio's help, the girl discovers that Lorusso lied to her but he, after apologizing, reiterates that he knows nothing about his brother's death. In the meantime, Pellecchia and Grandolfo discover that Manzari has a farmhouse in the countryside and Damiano's body was found right nearby: during the search, the boy's backpack is then found and therefore the professor is placed in custody even if he denies being involved.

Fenoglio does not believe in Manzari's guilt and begins to interrogate several victims of quick kidnappings. Pellecchia confides in him that he committed serious crimes years before with his colleague Savicchio; the marshal is surprised but asks him not to report himself until the end of the investigation. In the meantime, Grimaldi finds refuge on Marco Lorusso's boat, who is also helping him with some business in Montenegro . Fenoglio and Pellecchia track down their colleague Tonino Ruotolo and understand that he is behind Damiano's kidnapping: when they confront him, a fight breaks out and the corporal is grazed.

Ruotolo decides to follow his colleagues to whom he confesses that he kidnapped Damiano together with Savicchio to earn money but the child had died by accident; the two officers thus decided to hide the body near Professor Manzari's farmhouse to put the blame on him since he already had a criminal record for pedophilia. Fenoglio and PM D'Angelo now hang out even after work and end up kissing; the marshal has been in crisis with his partner for some time but he steps aside almost immediately. Fenoglio and his team have to gather damning evidence against Savicchio and so they place bugs in his apartment. Pellecchia is convinced that he is hiding the Grimaldi ransom money in the house and convinces Fenoglio to carry out a search: he himself will find the loot in the ceiling and put the handcuffs on his colleague. Shortly after, Pellecchia says goodbye to Fenoglio and goes to report himself for the crimes committed in the past together with Savicchio. On the same day, July 19, Judge Paolo Borsellino dies in Palermo. In the evening, Fenoglio accompanies D'Angelo home but refuses her invitation to go up and, instead, joins his partner at the hotel; the PM has already decided to distance herself from Lorusso, even more so now that the case on his brother's death will be reopened. In the meantime, the boss Grimaldi has disappeared without a trace.
