"Mr Di Pietro, I am writing to you not only to wish you well in your work investigating bribery and corruption, especially now that some people would like to erase and cover up everything. I am also writing to bring to your attention, as well as to your listeners, an investigation that appears today in Corriere della Sera, which could be entitled: Where are they now? The protagonists are all people who passed through your office at the time, Dr Di Pietro: namely, those investigated, suspected and accused in the Mani Pulite investigation."
