Cecily Sawyer: How to Crack a Code

The second thrilling, mysterious and very, very funny CECILY SAWYER mystery, from the award-winning author of EINSTEIN THE PENGUIN.​

Cecily Sawyer is surrounded by spies. They’re everywhere – on the streets, in her home, at her school – and after intercepting a highly suspicious message intended for her parents (also spies), Cecily, along with her highly-intelligent pet mouse, Mrs Maple Syrup, decides to investigate.​

And the more that Cecily digs, the further the mystery deepens … forcing her to question who – if anyone – she can really trust.

Hugely gripping, incredibly funny, and highly original, and brilliantly illustrated throughout by David Tazzyman, How to Crack a Code is an unputdownable mystery – perfect for fans of Robin Stevens and Katherine Woodfine.
