Former corsair turned pirate, Olivier Levasseur, also known as "The Buzzard", is known to have hidden one of the biggest treasures in pirate history, estimated at over 4. 5 billion euros, and leaving a cryptogram (with templar alphabet) behind with its whereabouts. In 1994, Bibique, whose real name was Joseph Guy Germain Tipveau, discovered a hint between the manuscript and a rock (discovered at the Ravine of Despair) exposed at the City Hall of La Possession, in the isle of La Réunion. In 1949, while sick with malaria, Reginald Cruise-Wilkins met Captain Goldvorg, who introduced him to Madam Rose Savy. At her house, he found out that she had discovered engraved marks and demarcation lines on rocks during the 1920s, leading her to the conclusion that those were pirate symbols. She visited the French National Library (Bibliothèque Nationale de France) and received confirmation that the documents she possessed originated from La Buse. Cruise-Wilkins bought those documents for $29, after that, he started great searches for the treasure. He found only a flintlock rifle, sword blade, figurines and a few coins, a pale reward for a 30,000 sterling pounds investment. After his death in 1977, John Cruise-Wilkins took on his father's search (siding with an American investor) using dynamite on the coastal rocks. Jacques and Edward, two other treasure-hunters, searched deep in the jungle, where they discovered ruins, an old coffer, a bell, lanterns, and bones (they were at odds with Wilkins after a quarrel, where they supposedly fabricated markings on the rocks). A popular story tells that many other pirates buried their own treasures in the same island, such as Hodoul, Boudin, Avery, Kid, Halsay or Taylor. Nowadays, John Cruise-Wilkins still searches for the treasure of La Buse, in the Seychelles, at the site of Bel-Ombre, north of Mahé. There he found a cavern with a network of tunnels. He indicated that all modern technology is useless because of the omnipresence of minerals & Iron Pyrite ("Fool's Gold") inside the rocks.
