1992. Colonna is offered a fee he can’t refuse to ghost-write a memoir. His subject, Braggadocio, is convinced that Mussolini’s corpse was a body-double and part of a wider Fascist plot. When a body is found, stabbed to death in a back alley, even Colonna is jolted out of his complacency.

Fuelled by conspiracy theories, Mafiosi, love, corruption and murder, Numero Zero reverberates with the clash of forces that have shaped Italy since the Second World War.
