Alexandre Dumas, the renowned French novelist, attends a dinner party hosted by Gioachino Rossini, the celebrated Italian composer. During the gathering, a unique idea emerges: to create an opera in an unconventional manner, with the music composed first, followed by the development of the storyline and lyrics. However, the choice of a Nordic-inspired theme proves to be a point of contention, as it deviates from the traditional Italian operatic style. The subsequent chapters recount the unfolding of the story, which ultimately remains unfinished, with Rossini composing only the overture but never completing the score. Despite the lack of a fully realized opera, the narrative itself takes shape, providing a glimpse into the creative process and the interplay between different art forms.
