Investigators! Series

by
(150 reviews)

InvestiGators is a new comic-style series from John Patrick Green, perfect for fans of Dog Man and Captain Underpants aged 7+.
 
Mango and Brash are alligators and investigators! This super-spy duo of sewer-loving agents fight crime and solve mysteries undercover. Using their Very Exciting Spy technology and their tried-and-true, toilet-based travel techniques they are ready to crack any case and defeat the super-villains.
 
This mystery series set in the sewers is ideal for emerging readers and graphic novel fans, as well as kids that prefer illustrated fiction. We love the colour illustrations, silly humour and comic strip layout.
 
Keen illustrators will also enjoy the instructions on how to draw the characters. It’s a great introduction to the world of graphic novels.
