Lupa, a secret agent during the First World War, is the son of Sherlock Holmes and Irene Adler.  It is strongly implied that he is the younger version of fictional detective Nero Wolfe in the mystery series by Rex Stout.  Auguste Lupa is one of many aliases used by the character.  Jules Giraud, the narrator of the books, explains that Lupa always chooses as his alias a first name with a connection to one of the Caesars.  Auguste is the name of a Roman emperor and Lupa means "wolf."  Other aliases he has used include Julius Adler and Cesar Mycroft.  The latter surname indicates a connection to Mycroft Holmes, the brother of Sherlock Holmes.  In "Rasputin's Revenge" it is revealed that his real name is John Hamish Adler Holmes, combining the names of Dr. John Hamish Watson, the best friend of Sherlock Holmes, and Irene Adler's surname with the surname Holmes.
