Cluedle Series

(11 reviews)

Calling on all sleuths aged 8+! The Cluedle books are perfect if you love mysteries, puzzles and cases that need cracking and are different to most mystery books in that the reader gets to actively solve each story!

All written by Hartigan Browne, each book in the series features 50 or more puzzles that need to be completed to solve a new case. From missing puppies, to crimes at sea and Christmas capers, you will have to work your way through the many puzzles to get to the bottom of each mishap and become a successful detective! The activities throughout are perfect if you love word searches, maths problems, cracking codes and reading maps, making for the most interactive read that even reluctant readers will enjoy.

The books do not have to be read in any particular order, as each book has a new set of characters and is placed in a new setting, and if you're worried you might get stuck at any point in the book, you can just turn to the back where you'll find a list of solutions. 

If you decide to give these books a go and discover you love a good mystery, do also check out our list of the Best Crime and Mystery Series for 9 and 10 year olds, where you'll find more recommendations.
