Review: Codebusters by Dan Metcalf

This book is an entertaining, easy read which opens a door to cryptography for a Key Stage 2 readership. It is produced by Bloomsbury’s Black Cats imprint, a set of fast-paced stories with illustrations throughout, designed to appeal to even reluctant readers.

Jackson Hilbert has to move schools, to Bletchley Grange, mid-term and decides to re-invent himself as “Jax” a popular footballer rather than the maths geek he was viewed as at his last school. However, he just can’t stop his competitive edge getting the better of him in a prime number challenge in his first maths class, and following a little code-cracking he is recruited by the “codebusters”!

Before his first week at Bletchley Grange is over, he is embroiled in deciphering a trail of clues alongside Jasper Newton, Michelle Chang and Charlie Babbage, to discover the whereabouts of a stolen school trophy. With guidance from the super-intelligent Captain Sir Alastair Horacio Turing PhD, this team of smart kids pool their talents to take on the challenges that the mysterious ”Elgar” has set for them.

I love the way that the author, Dan Metcalf, has played with the names of his characters and introduced ideas such as the Caesar cipher, which could spark an interest in the discipline of cyber-security in young readers. For those intrigued by secret codes, more information and some fun worksheets can be found on the author’s website: danmetcalf.co.uk I would certainly recommend this book as an entertaining read for children of 8+ and a great cross-curricular resource for accompanying aspects of the Key Stage 2 computing curriculum.
