InvestiGators books in order

Ages 7–10 · about grade 2 comic · still going

There are 9 InvestiGators books. Start with InvestiGators (2020) and read them in number order. The newest is book 9, Weather or Not (2026). Peabody's own estimate: Bookroo and Linden Tree Books both give 7 to 10 for the newest book, but neither is the publisher, and Macmillan's pages would not open for us.

What reading it is like: Full-color comic panels with short speech bubbles and a pun or wordplay joke on nearly every page.

What's next for InvestiGators

  • Agents of S.U.I.T.: A spin-off series by John Patrick Green with Chris Hastings in the same world. Bookroo lists four books: Agents of S.U.I.T. (2023), From Badger to Worse (2024), Wild Ghost Chase (2025) and Sew Much Trouble, the fourth, out 17 February 2026.
  • Case Files: A special solve-along edition with six new mysteries for the reader to work out. Listings give 2025, but the day varies between sellers, and it isn't numbered in the main run on Bookroo.
  • High-Rise Hijinks: Wikipedia lists it as a 2024 World Book Day title for the UK. It isn't in the numbered US run.

Do you have to read InvestiGators in order?

Each book is a separate case, so a child can start with book 1 or pick up any later one. Reading in number order is nicer, because the two main characters and the people around them grow more familiar and the running jokes build. Nothing is spoiled if you jump in the middle.

What age is InvestiGators for?

Seven to ten is our estimate from bookstore and review listings, which differ a little from book to book (Bookroo shows 7 to 9 on a couple, 8 to 12 on book 8). The comic panels carry the story, so younger children can follow it read aloud, and the puns suit a reader who enjoys wordplay. We don't print reading-level scores: they belong to the companies that make them.

What's it like inside InvestiGators?

  • Which way: Left to right, like most books.

About book 1. The page count is from openlibrary.org; the rest is Peabody's own note, never a score.
