What to expect

Laugh yourself silly with the InvestiGators! Crime-fighting alligators Mango and Brash are back in Off the Hook – the third adventure by John Patrick Green, perfect for fans of Bunny vs Monkey.

'Fast, fabulous, and fantastically funny' – Jamie Smart, creator of Bunny vs Monkey.

After escaping from the InvestiGators, villains Crackerdile and Hookline and Slinker are back and badder than ever! Rob a bank? Check. Find a secret lair? Check. Kidnap a giant chicken? Check.

Luckily, Mango and Brash are hot on their tail with their hi–tech Very Exciting Spy Technology (V.E.S.T.s). Do the InvestiGators have what it takes to catch the crooks or will the vile villains slither away from justice?

The InvestiGators series is a hit with readers of all ages and covers positive themes like:

Fun teamwork
Never giving up
Pesky problem–solving

Listen to the whole series: InvestiGators, Take the Plunge, Ants in our P.A.N.T.S and tons more. Don't miss Agents of S.U.I.T., the spin off series featuring Mango and Brash's colourful coworkers.

Critics Review

Has heaping helpings of surreal alligator action and wordplay gags to keep new readers bent on solving the mystery.

The New York Times

A hilarious ride with great wordplay, bright illustrations and plenty of twists and turns – lots to keep young readers engaged. Keen illustrators will also enjoy Green’s bonus drawing tips to create their own InvestiGators.

The Scotsman

In high-intensity colors, straightforward panel artwork by Green (Hippopotamister) offers plenty of slapstick gags to Brash and Mango’s tale. Fast-paced fun for the bad pun and dorky joke crowd.

Publisher's Weekly

Like the heroes of Dav Pilkey’s Dog Man or Captain Underpants, the Investigators are bound to resonate with kids.

School Library Journal: XpressReviews

With its rampant good-natured goofiness and its unrelenting fizz and pep, this feels like a sugar rush manifested as a graphic novel. Silly and inventive fast-paced fun.

Kirkus

If your young reader is looking for something to fill a Dogman-shaped hole in their personal libraries, let alligator investigators Mango and Brash step in. With a detailed comic-strip format, lots of toilet humour and zany plot lines, you will be pestered for the sequel before it's published.

Sunday Business Post (Ireland)

InvestiGators is a visual and verbal delight… and guaranteed to please even the most reluctant reader!

Lancashire Post

Whatever your rating system is this book smashes it and is something that should be in all KS2 classrooms as far as I’m concerned.

My six year old nephew would not put this book down . . . We can’t wait for more books in this series to be released!

Toppsta review

pun-heavy whodunnit graphic novel which is just as clearly laid out, colourful and silly as Dav Pilkey’s phenomenally successful series. Mango and Brash are an excellent detective duo that readers will definitely want to see more from…

BookTrust

Simply bursting with youthful energy, crazy comedy, vibrant artwork and breathtaking creativity, InvestiGators is a visual and verbal delight… and guaranteed to please even the most reluctant reader!

Lancashire Evening Post

Absolutely hilarious and fantastic book. Investigators has become a good new series to look out for and we simply can't wait to continue the story. My son and I went through the whole book in one sitting. Mango was my son’s favourite as he was extremely funny. The book has great design and vibrant colourful pictures. The puns and jokes are spot on

Toppsta review

It’s like a cartoon you can read, the illustrations are so good it’s like you’re watching them and not reading them at all.

The Reading Agency

My son loves this graphic novel and finds it hilarious
