Peretti summons the police to the Moroni family home, and with the entire family present, proceeds to excoriate the killer for killing in cold blood while overlooking the one detail that revealed his identity. Peretti then produces the mirror, and upon showing the back of it to Beniamino, he screams before someone cuts off the lights in the room. Once the chaos settles and the lights are turned back on, Oliviero is found sobbing in the corner behind a chair. He admits to having killed Stefania and her father out of jealousy for the latter's wealth, and all the others in an attempt to cover his tracks.
