Detective "Smile of Gioconda" was written by the outstanding English prose writer Aldous Huxley, known to the mass Russian reader for his novels "Counterpoint," "Yellow Krum" and especially the dystopia "Wonderful Brave World." Connoisseurs of Huxley's work know that he was a hereditary aristocrat, the grandson of the famous philosopher Thomas Huxley (it is in this transliteration that he is known to us). But first of all, he was a real gentleman, and therefore simply could not help but write a detective novel.
