6x19 - Distretto di Polizia

Investigating an arson attack, Alessandro and Irene meet a colleague from the explosives department who suspects a young but repeat offender. Simonelli takes it personally because he saw his best friend die during a fire set years earlier by the same deranged man. But Irene realizes that things are less straightforward than they seem, while Roberto manages to arrest the perpetrator of the car bomb commissioned by Patriarca.
