Lord Archibald knows the school year is off to a bad start when he is kidnapped and then dramatically rescued by a sword-wielding stranger. No complaints if you're a princess—but not so great when you're a scrawny son of a duke in 19th-century England. When other boys are also attacked, it becomes clear that someone is out for blue blood in Wyndsor, England's School of Kings. Archie must put aside his bumbling ways, don his sleuth's hat and figure out who's behind the sinister attacks, and what they're really after, before it's too late!
