Bestseller listMerchandise
Adults love it too

The series' first art heist, and the first time creativity_and_imagination becomes a lead deep theme. Green transplants Mango and Brash into a museum setting with the same commitment he brought to sewers, giant ants, and boulders, and the hide-and-seek pun in the title earns its place.

What’s it about?

The story.

Heist and Seek marks a tonal shift for the InvestiGators series: where earlier books placed the agents inside disasters or mysteries, this one sends them into the world of art crime. The art_heist plot engine and museum setting give Green new visual territory, the contrast between the agents' sewer-trained instincts and the rarefied gallery world is exactly the kind of absurdist collision the series excels at. The creativity_and_imagination deep theme (0.7) is new to the series and fits naturally: a heist plot requires improvisation and invention, and the art setting foregrounds what creativity looks like under pressure. The fairness_and_justice deep theme (0.6) reflects that something has been taken that shouldn't have been, there's a moral clarity to the mission that earlier books grounded more in pure comedy. The interested_in_art_and_creativity reader_situation (0.5) is also new for the series, suggesting this book has crossover appeal for children who don't usually reach for spy comedy. The 'heist and seek' title pun is classic Green: it works on multiple levels, and the hide-and-seek dimension (what exactly is being sought, and what is hidden) is presumably central to the plot.

Why it lands

Why they love it.

Why kids love it

The specific kick is the art-heist setup — Mango and Brash transplanted from their usual sewers into a posh art museum, sewer-trained instincts meeting fine-art etiquette. The InvestiGators that turns the agents into rumpled detectives in a gallery, which is funnier than it sounds.

  • Adventure and freedom
  • Becoming invisible
  • Being a detective
  • Having a nemesis
  • Having a secret base

Why parents love it

The InvestiGators where the agents work an art heist — gallery setting, rare painting, a clear moral mission. Slightly more genuine detective story than the earlier books while keeping the pun-density intact. Useful crossover pick for kids interested in art who also like comedy.

  • Shared humour
  • Quick to read
  • Conversation starter

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.
