Can a crafty fox and a genius chicken complete an epic rescue mission... without one of them getting eaten? A funny action-adventure story from bestselling children's author Dermot O'Leary, with glorious illustrations from Claire Powell.

Charles Redfearn is one of Britain's very best spies. He's dashing, he's clever . . . but he can't stop chasing chickens. He is a fox, after all.

When his French cousin goes missing in action, along with some vital war plans, Charles is forced to pair up with Gertrude Featherhorn - chicken and master code-breaker - to have any chance of a successful rescue. But will he be able to control his appetite?

Featuring the cunning French Resistance, a daring castle break-in and a race against time to stop plans falling into the wrong hands, Charles and Gertrude's mission is going to be even more important than they could have imagined!

Set during the Second World War, this amazing story brings history alive in a brilliantly fun way for readers aged 7-12.

Dermot O'Leary is the bestselling author of the Toto the Ninja Cat series and Wings of Glory.
