There was something about the Burolo case which was different any other he had ever been involved in. He had known cases which obsessed him professionally, taking over his life until he was unable to sleep properly or to think about anything else, but this was even more disturbing. Inspector Zen has a problem: an impossible murder, recorded on the closed-circuit video of Oscar Burolo's top-security Sardinian fortress. As he gets to work, he is once again plunged into a menacing and violent world where his own life is soon at risk.
