The story of a professional diver and his son provides the broad outline the author uses to create a very funny mystery novel which at times comes close to the grotesque comedy of Mortadelo and Filemón. Ernesto’s family life shatters stereotypes, as he is forced to live where his father works, in other words, on a boat. His mother, who was more restless, left them to go live with the modern pirate Barbaverde. The author’s sarcasm and irony are expressed through Ernesto, whose audacity will lead him to gather the clues that will reveal the dark secret behind the great anchovy factory and help him find his father, who has mysteriously disappeared.
