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.
An Unputdownable and Whip-Smart Spy Mystery for Children
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, 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.

Praise for Cecily Sawyer: How to be a Spy:
"With so many undercover agents vying for attention, the choice can seem daunting – but Cecily Sawyer: How to Be a Spy, a delightful new adventure by Iona Rangeley, shows the detective formula working at its best… Rangeley is a witty, beguiling writer – and what follows is a neatly plotted adventure, in which each clue forms part of a puzzle which the reader can piece together as the narrative rips along." – The Telegraph
"Whip smart, absolutely hilarious and full of charm." – Laura Noakes, author of Cosima Unfortunate Steals a Star
"A fabulous book" – Zohra Nabi, author of The Kingdom over the Sea
"A charming and elegant corrective to the notion that 10-year-old girls and mice have no role to play in espionage." – Luke Jennings, author of Killing Eve
"I firmly recommend this book. A very good start for those who want to join the profession or who just want a good read." – Sir John Scarlett, former Chief of MI6 (really)
