Clue Tracker's Field Journal: An unofficial research companion inspired by The 39 Clues

Clue Tracker's Field Journal is an unofficial, independently created resource. It is not affiliated with, authorized by, endorsed by, approved by, licensed by, or sponsored by Scholastic Inc. or the authors of The 39 Clues. All characters, settings, and trademarks referenced from The 39 Clues are the property of their respective rights holders.

Your reader doesn't just finish the books — they work the case.

Clue Tracker's Field Journal is a print-your-own companion that turns reading the series into hands-on research. As the story unfolds, your child becomes the investigator: logging the characters they meet, digging into the real historical figures woven through the plot, mapping the real-world places the trail travels to, and tracking the clues as the mystery comes together. It's reading, writing, geography, and history — documented by hand, one book at a time.

What's inside — 22 pages:

- Welcome + grown-up instructions — a simple start: read the books, then document the adventure.

- Operative Dossiers — a template for recording each character and where they fit.

- Ancestral Files — research cards for the real historical figures the series introduces.

- Global Field Reports — location cards for mapping the real-world places the story visits.

- Clue Recovery Log — pages for tracking leads, clues, and evidence, with a plain-language explainer on how they differ.

- Mission Debrief — a reflection page to complete after each book.

- Instructor Notes — a grown-up reference listing the real historical figures (by name and book) and the world locations featured across the series, so you can prompt your reader and check their work.
