About the Book:
FROM THE MEGA BESTSELLING GRAPHIC NOVEL SERIES
Tackle tricky cases in this solve-along Investigators adventure, along with everyone's favorite sleuths Mango and Brash!
Special agents Mango and Brash are back again, and this time they’ll be 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! 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!
About the Author:
John Patrick Green is a human with the human job of making books about animals with human jobs, notably the smash-hit graphic novel series InvestiGators. John is definitely a multiple New York Times-bestselling human author and not just a bunch of animals in a trench coat pretending to have a human job. With over three million copies of InvestiGators in print, John is a successful human being with only two hands and a normal amount of fur. He lives in a Brooklyn apartment that doesn't allow animals other than the ones living in his head.
