...And Let's Talk About Noble Adventurers:
Saint Christopher, Caribbean: A ship that sank along with an immense treasure on a forgotten island centuries ago, four playing cards which, when combined, hide the exact message for finding the lost treasure, and three "noble adventurers," Corto Maltese, the magnificent aesthete Rasputin, and a descendant of a fierce pirate...

The Cause Was a Seagull:
Seagull Island or Marakotokua, a fictional island invented by comic creator Hugo Pratt and supposedly located in the British Honduras [Belize] on the northwestern coasts of the Caribbean... stranded on the beach, Corto Maltese disturbs a seagull's nest which attacks him... he is left exposed and gets wounded in the head by a bullet.
