"When I'm faced with a Pilkey fan looking to branch out, this graphic novel is the first book I reach for." ―The New York Times

With more than four million copies in print, #1 New York Times-bestselling author John Patrick Green's goofy graphic novel series is a colossal comics hit! Join super spy alligator duo MANGO and BRASH as they surf the sewers and fight the forces of evil.


Special agents Mango and Brash are asking their readers for help in cracking the case! The gators have been given a brand new add-on for their V.E.S.T.s to help with gathering evidence and making sense of clues - the G.R.I.D. (Gator Reasoning, Inquiry, Deduction) - and with that powerful tool in hand, kids can follow along as they solve six brand-new mysteries all by themselves! Featuring plenty of familiar faces from investigations past, as well as a few brand new suspects, Mango and Brash and YOU (the reader) will get to the bottom of cases big and small!

John Patrick Green

John Patrick Green lives and works in New York City where he makes books and comics about animals with human jobs, notably the smash-hit graphic novel series InvestiGators - and its spin-off Agents of S.U.I.T. He's worked as a comics consultant for Disney, Nickelodeon and Dreamworks. With over four million copies of InvestiGators - starring Mango and Brash the sewer-dwelling crime busters - in the wild, he also creates artwork for video games. He lives in a flat in Brooklyn that doesn't allow any pets, or animals, so he has to make do with the ones living in his imagination.

Just because Steve Behling sleeps with the lights on, doesn’t mean he’s afraid of monsters. Or maybe it does? Anyway. Obsessed with comic books and old horror movies since he was a kid, Steve loves to tell stories. Some of his works include the original middle grade novel Agent Stitch: A Study in Slime, the Marvel Monsters Unleashed chapter book series, and many others. Steve lives in a top secret subterranean lair with his wife, two human children, and an awesome shelter dog, Loomis, who is afraid of monsters because he is smart.
