Lojacono and Di Nardo go to see Biagio's ex-girlfriend to ask her one more question. She happens to remember something that gives them a new lead. They then go and talk to Renato, Biagio's friend and colleague.

Lojacono is confident he knows how the murder happened and is able to trick Renato into saying something he couldn't have heard on the news.

The case has been solved, one gets the feeling that if the murderer had been Varricchio, a common ex-convict, instead of a promising biologist, son of a prominent professor, the outcome would have been more palatable to the city and to the press.

A parishioner shows up at police headquarters with photos she thinks are compromising. Lojacono and Alex then go to question the volunteers as to whether the insinuations could carry any weight.

Lojacono and Di Nardo go to church to be able to talk again with Don Michele. The priest confirms that he and Angela loved each other very much, but that they had no history. Lojacono only wants Don Michele to collaborate.
