Cecily Sawyer: How To Be a Spy

A thrilling, mysterious and very, very funny new adventure from the award-winning author of EINSTEIN THE PENGUIN. Cecily Sawyer has spent the evening in the attic, training her pet mouse, Mrs Maple Syrup – an unusually intelligent mouse, in Cecily’s opinion – when her parents disappear. Luckily, Cecily is more than ready to investigate such a thing. She has wanted to be a spy her whole life, and has all the spy handbooks, manuals and code-cracking kits a girl could need. But soon, Cecily discovers several very strange things in her city. She’s not the only spy out there – far from it, in fact. And Mrs Maple Syrup is not the only unusually intelligent mouse… This latest children's fiction is a top pick for both avid and reluctant readers. The story is filled with action, adventure, and a touch of humour that will keep readers of all ages engaged. For fans of Gennifer Choldenko (Mouse and His Dog), R. A. Spratt (Friday Barnes 5), Jonathan W. Stokes (Addison Cooke and the Ring of Destiny), Shirley Marr (All Four Quarters of the Moon), and Peter Brown (The Wild Robot). HarperCollins Children’s 2025
