Provenzano case

Provenzano used a version of the Caesar cipher, used by Julius Caesar in wartime communications. The Caesar code involves shifting each letter of the alphabet forward three places; Provenzano's ''pizzini'' code did the same, then replaced letters with numbers indicating their position in the alphabet. For example, one reported note by Provenzano read "I met 512151522 191212154 and we agreed that we will see each other after the holidays..." This name was decoded as "Binnu Riina".
