Son Altesse Sérénissime (His Serene Highness) or SAS is a series of espionage novels created by French author Gérard de Villiers, featuring Austrian prince Malko Linge as the main character. Since, more than 120 million copies have been sold globally, mostly in French, scoring in the top 25 of the best-selling book series of all time, behind Frédéric Dard's "San-Antonio" with 200 million copies sold worldwide.
Since 2006, the novels have been published as comic books, though intended chiefly for adults given their contents of violence and sex. 
The novel's title is a play on initials: "Son Altesse Sérénissime" (SAS) is the French version of "His Serene Highness" (HSH); and the British Special Air Service (SAS) is the principal special forces unit of the British Army.
In 2014, Vintage Books published posthumously English versions of "The Madmen of Benghazi" and "Chaos in Kabul," translated and adapted by William Rodarmor. The publisher released three other books in English through 2016.
Background.
Gérard de Villiers was a correspondent for "France-Soir" and other newspapers. He began writing the "SAS" novels in 1964, when an editor told him that Ian Fleming had died and that de Villiers might create the next James Bond. He succeeded; the series had sold about 100 million copies worldwide, comparable to the Bond series. It may be the longest book series in history written by one person.
Government officials and intelligence officers, who enjoyed seeing themselves fictionalized and reading about events they could not reveal publicly, told de Villiers secrets that appeared in "SAS", making the series' plots and settings unusually realistic. The books predicted some events such as the capture of Carlos the Jackal, assassination of Anwar Sadat, and events of the Syrian Civil War. Robert F. Worth, former Beirut bureau chief for "The New York Times", was amazed to read in "La Liste Hariri" details of the assassination of Rafic Hariri that no journalist knew when the book appeared. A Lebanese intelligence officer who wanted to reveal information but did not trust journalists (including Worth) helped de Villiers, the novelist said.
Hubert Védrine said that while Foreign Minister, before visiting a country he read "SAS" novels to learn what French intelligence believed about it. While the books' many detailed sex scenes give the series a poor literary reputation, "the French elite pretend not to read him, but they all do", Védrine said.
