Francesque Duquesne was an agent of the Shadow Directory in late 19th century Paris. He had curated its museum of antiquities, but when the Doll's House was stolen, he was exposed to its psychic residue and had a breakdown, so he retired to Charenton Asylum. The Seventh Doctor visited him there, and Francesque told him about his dreams of a toy shop where the Doll's House might be found. (PROSE: The Death of Art)

Francesque may be related to Marielle Duquesne, a Shadow Directory agent who appeared in PROSE: Christmas on a Rational Planet.
