The man who took the photograph to the paper has a long criminal record. Maltese has him followed and studies his habits and behaviour. Maltese also discovers that the man’s name pops up in one of the last cases Inspector Perlata was dealing with: the disappearance of a female student. He starts to investigate and discovers that along with the young woman her boyfriend also vanished, a young boxer, who was a friend of the man he is having followed. After arresting him, Maltese manages to make him confess and the Mafia’s involvement becomes a lot clearer.
