Jean-David Morvan brilliantly recounts the ferocious journey of the ruthless Toto Riina, a poor peasant from Corleone who became the supreme leader of the Sicilian mafia in the 1980s and 1990s. Nicknamed La Belva (the wild beast), described by his own henchmen as a man of implacable coldness and cruelty, the godfather of godfathers rose through the ranks of Cosa Nostra by spreading unquenchable violence.

Morvan imagines the mafioso at the dawn of his death in 2017, in his prison in Parma.
