Bodyguard and driver of Don Salieri.
We only meet him in the chapter
Bon appétit!,
where Carlo betrayed Salieri with a rival mafia family
Morello
and reveals the restaurant where Salieri will be staying for lunch,
himself, on the fateful day, suddenly excuses himself from illness to avoid the attack.
Carlo has a nameless lover, in whose apartment he lives.
It is there that Salieri and I will come for him right after the failed assassination attempt.
