The Secret Service is an American comic book series created by writer Mark Millar and artist Dave Gibbons, based on an original concept by Millar and filmmaker Matthew Vaughn. The series was first published in 2012 as a six-issue miniseries by Icon Comics, an imprint of Marvel Comics. It follows Gary London, a young man recruited by his uncle, Jack London, into a secret British intelligence organization known as Kingsman. The story combines spy thriller elements with Millar's trademark gritty, often satirical style, and features a plot involving a villainous tech mogul who threatens global population control. The series was later collected as a graphic novel and rebranded as 'Kingsman: The Secret Service' after the success of the film adaptation. It is set within the broader Millarworld shared universe, with cross-references to other Millar works such as Kick-Ass. The comic was critically acclaimed for its art and narrative, and its blend of traditional espionage with over-the-top action laid the groundwork for the film franchise.
