Paul Auguste Jean Nicolas Féval (called Paul Féval fils) (25 January 1860 – 15 March 1933) was a French adventure novelist, like his father Paul Féval, père. He was the third of eight children and the eldest son of Paul Féval, who was 42 years old and at the height of his success when Paul Féval fils was born.
Paul Féval fils became famous for writing sequels and prequels to his father's popular swashbuckler novel Le Bossu [The Hunchback] (1857), starting in 1893 with Le Fils de Lagardère [The Son of Largardère]. In 1914, he wrote Le Fils de d'Artagnan [The Son of d'Artagnan]. After that he published a more ambitious saga, pitting d'Artagnan himself against Cyrano de Bergerac.
Paul Féval fils' The Years Between series (French title d'Artagnan contre Cyrano) published in 1925 was written with M. Lassez and consists of four books: The Mysterious Cavalier, Martyr to the Queen, The Secret of the Bastille, and The Heir to Buckingham. These books supposedly fill in the missing twenty-year gap of d'Artagnan's life that Alexandre Dumas, père omitted between his stories of The Three Musketeers and Twenty Years After. Feval's stories take place in 1641, one year after Edmond Rostand's play Cyrano de Bergerac takes place.
In it, young Cyrano befriends a "Mystery Knight", who is revealed as the illegitimate son of the Duke of Buckingham and Anne of Austria, the Queen of France. On the other side politically is d'Artagnan who is helping Cardinal Richelieu and his successor, the wily Mazarin, to kidnap young George to use as leverage on the Queen to enlist Spain on the side of France. But d'Artagnan is still loyal to the Queen's family and uses his mission to help her son reclaim his inheritance. At first enemies, d'Artagnan acquires a grudging respect for young Cyrano, who is a little jealous of his elder. They then become true friends and allies. Aramis guest-stars.
