The creation of this little aperture of Tintin began in the tropics, where the story takes place : Madagascar. Some time ago, I began a long story, but years passed and still there had been little advancement. On the one hand, I wanted to continue The O-Light Project" (that was the original title of this adventure), but on the other, I very much wanted to "try my hand" at another type of story, a simpler idea of less importance. To try my hand at inking, my rhythm of storytelling, my ability to create suspense, my sense of humour ...
... And the idea came, in a few hours, during a voyage between Tananarive and Tamatave (a harbour town where you can travel by plane or boat to Saint-Marie - Nosy Boraha - the island where the action unfolds).
In the beginning, the idea was basically that Tintin and Haddock went diving ... in wetsuits,which had been curiously absent in the work of Herge (except in the film 'Tintin and the Golden Fleece'). Again, I still failed to find any intrigue, other than that of a treasure hunt or the eternal struggle against villains. Suddenly, an idea popped into my head: "The Speaking Fish." Was Tintin going to discover a mysterious creature with the power or speech? Why not?
After many reflections, I began on this improbable tale, desperate to avoid the possible pitfalls of which I was well aware. The story, in my head only, not written, seemed to stay together to the end.
