Don Juan Triumphant - The Novel

The Novel

In the novel by French novelist Gaston Leroux, Don Juan Triumphant (French: Don Juan triomphant) is an unfinished piece that the Phantom had been working on for a period of 20 plus years. At one point, he remarks that once he completes it, he will take the score into the coffin he uses for a bed and never wake up. The Phantom plays a section of his opera following his unmasking at the hands of Christine Daaé, who is stunned by the power of the music.

The narrator comments that the work was never found in the 30 years since the Phantom's death, and speculates that it may still be in his house next to the subterranean lake beneath the Paris Opera. Gaston Leroux had thought he had found the remains of Erik, but without notes/letters from Christine Daae, the Persian, and others he would not have found them.
