5 Is The Perfect Number by Igort

This graphic novel follows an aging, retired Neapolitan hitman whose quiet life is shattered by violence; drawn back into the world he left behind, he embarks on a deliberate, vengeful odyssey to settle old scores, confronting memory, mortality, and the grim codes of organized crime. Rendered in stark, cinematic black-and-white art, the story blends noir mood, spare dialogue, and brutal action to examine guilt, honor, and the cost of a life of violence.
