Ignazio Busoni Dies of Heart Attack
Ignazio Busoni suffers a fatal heart attack in an alleyway near the Duomo. Before dying, he leaves a voicemail for his secretary, Eugenia Antonucci, with a message for Langdon. He says the mask is safely hidden and gives a clue: 'Paradise Twenty-five.' He also says 'the gates are open to you.'
