I had not read Pérez Reverte before, but I have discovered that he is an extremely great narrator. Apparently, he is well-versed in the schemes and compositional strategies of the classic American noir novels.
In this story, he demonstrates a great knowledge of sailing. It is possible that this is one of his great hobbies.
The intrigue revolves around the ambition of his characters: extreme in the main protagonists and non-existent in the secondary ones. This contrast in ambition creates a complex web of relationships and motives that keeps the reader engaged from beginning to end. Pérez Reverte's ability to develop such multi-faceted characters and a captivating plot is truly remarkable. His detailed descriptions of the sailing vessels and the sea add another layer of authenticity to the story, making it feel as if the reader is right there on board, experiencing the adventure along with the characters.
