National treasures, criminal masterminds, and…secret agent librarians? Steve Brixton wants to be a crime-busting detective—just like his favorite crime-busting detectives, the Bailey Brothers. Turns out, though, that real life is nothing like the stories. When Steve borrows the wrong book from the library, he finds himself involved in a treasonous plot that pits him against helicopter-rappelling librarians, has him outwitting a gaggle of police, and sees him standing off against the mysterious Mr. E. And all his Bailey Brothers know-how isn’t helping at all! Worst of all, his social studies report is due Monday, and Ms. Gilfeather will not give him an extension!

When a missing surfboard proves to have hidden depths, twelve-year-old super-sleuth Steve Brixton must go undercover—and underwater—to tackle a puzzling tangle of mysteries. Steve Brixton’s finally gotten a hang of this super-sleuth thing. After a few months of busting bad guys he finally has his own office—even if it’s a bit small, and outside, and okay, used to be a doghouse. So when someone asks him to help track down a board stolen by a local surf gang, it’s just a matter of slipping into a neon wetsuit and blending in with the surfers—right? But when the assignment goes all wrong, Steve is going to have to test his wits against pirate smugglers, thick-necked goons, and a sixth-grader who just wants his gym shorts back—all with the help of the tips and tricks he learned from his beloved Bailey Brothers books, of course!
