We are grateful to the magistrates Giancarlo Capaldo and Nicola Gratteri, and Deputy Public Prosecutor Galileo Proietto of the District Anti-mafia Office of Milan, for their help.
We would also like to thank Maurizio Belpietro and Ferruccio de Bortoli, without whose advice this book would not have been published.
Our thanks are also due to Giuseppe Di Bella and Filippo Barreca for their courage in coming forward with their information; to investigators such as Giovanni Capello; to Barbara Reggiani for her meticulous work in transcribing the recordings; and to all the other people who have contributed to the publication of this book and who for various reasons cannot be named.
Lastly, we would like to thank Camilla and Valentina for their trust and patience.
