When the detective agency is flummoxed by a spate of mysterious crimes, they enlist the help of a brilliant young detective (the reader) to crack the case. The agency asks them to infiltrate the inner circle of a criminal mastermind, Silas Ridley, who used to work as a police puzzle specialist. To help with their work as a mole, they give them an actual mole, who is an expert tracker! Can the reader help bring the criminal to justice, solving one Detectogram® at a time?

Packed with a mix of 46 logic, visual and text-based puzzles. From clues to unravel, maps to navigate, suspects to examine and secret codes to crack, there’s plenty of fun and perplexing puzzles to be solved in this brain-busting mystery for young super sleuths.

Perfect for fans of detective-themed activity books, such as the bestselling Cluedle and Murdle Junior, and the crime-solving adventure series Sherlock Bones.
