Crookhaven: The Beloved Book Series Heads to the Small Screen

Fans of the thrilling middle-grade book series Crookhaven have reason to celebrate: a television adaptation is on its way to BBC Television in 2026. Based on the novels by J.J. Arcanjo, the series promises to bring the world of aspiring young thieves and their unconventional school to life.

What is Crookhaven About?

Crookhaven centers around a unique boarding school that trains students in the art of thievery – not for malicious purposes, but to right wrongs and help those in need. Instead of facing arrest, students like the protagonist are invited by the enigmatic Caspian Crook to hone skills in lock-picking, forgery, and “crim-nastics.” The goal? To con the bad guys and redistribute wealth to the innocent.

The Books in the Series

The Crookhaven series currently consists of five books:

• The School for Thieves (2022) – The first book introduces readers to Crookhaven and its unconventional curriculum.
• The Forgotten Maze (2023) – The second installment continues the adventures of the students as they face new challenges.
• The Island Heist (2024) – The third book sees the students embarking on a daring heist.
• The Impossible Fortress (2025) – The fourth book presents the students with their most challenging task yet.
• The Thieves’ Revenge (2025) – The final book in the series, soon to be adapted for television.
