PISTA Nº 01

The book is still closed. Good.
Open it slowly. Read what Massimo left in his apartment on the Aventino. Read what I wrote in his agenda. Then the seventeen clues. Apply them with a red pen, name by name, page by page. Forty-seven thousand names. One of them is the killer.
The eighteenth clue is not among the seventeen. It is in the page that faces him. When you find it, you will know.
