Corto Maltese, Steiner, and Tristan Bantam sail for Bahia to meet Morgana, Tristan’s half-sister. She has their father’s notes concerning the lost continent of Mû, the very papers Tristan glimpsed in his dreams; even the Indians have predicted that his fate lies there. But in Bahia, a lawyer by the name of Milner tries to kill Tristan.
Corto exposes Milner and beats him at poker; he wins and Milner loses his life. The treasure hunt can now continue on its way towards Itapoa.
