What’s it about?

The story.

Mango and Brash, the toilet-travelling alligator agents of S.U.I.T., have a dairy disaster on their claws: the city's water supply has been replaced with milk, and the newest feline recruits, the InvestiGatos, don't seem to mind one bit. With monkey-scientists lurking behind the scenes and the rain falling a suspicious shade of green, the InvestiGators must sniff out the culprits before the whole city curdles. John Patrick Green delivers another full-colour explosion of terrible puns, madcap gadgets and slapstick chases in his hugely popular series. Fast, loud and relentlessly silly, it's catnip for reluctant readers and comic fans who like their mysteries served with a side of groan-worthy wordplay. Read it in sequence or dive straight in.

Fit check

Where it lands by age

Aimed squarely at 7-10s reading independently, with humour that works read aloud from about 6. The comic format and punchy pacing make it a reliable win for reluctant readers, and each case stands alone so newcomers can start anywhere.

Why it lands

Why they love it.

Why kids love it

The alligator agents travel by toilet, fight monkey-scientists and crack a pun on nearly every page. When the city's water turns to milk and the rain runs green, the chaos is exactly the kind of fast, gross, funny nonsense that keeps readers flipping panels.

  • Adventure and freedom
  • The underdog winning

Why parents love it

Book after book, the InvestiGators turn resistant readers into page-turners. The wordplay is clever enough to raise an adult smile, the format is inviting, and each volume stands alone so there's no homework before diving in.

About the author & illustrator

John Patrick Green.

JP

John Patrick Green

Writer & illustrator · United States

John Patrick Green is an American author-illustrator best known for the InvestiGators graphic-novel series, a fast, pun-heavy detective comedy starring two alligator agents of S.U.I.T. He also writes and draws the Kitten Construction Company picture books and the Hippopotister graphic novels. Green's style is clean-lined, cartoon-bright and gag-paced, with a strong vocabulary of visual jokes and groan-out-loud wordplay that lands well on read-aloud and gives confident young readers a steady comic engine to chew through. Strong reluctant-reader appeal for ages 6–10, particularly children who already love Dav Pilkey or Aaron Blabey. InvestiGators has been a New York Times bestseller across the run.
