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.

Charles Fox is one of Britain's very best spies. He's dashing, he's clever... but he can't stop chasing chickens! And, during the Second World War, there is a VERY important agreement between all the animals that they won't eat each other. So Charles finds himself locked up for his own good.

Then his French cousin goes missing in action, along with some vital war plans, and Charles is the only one with the expertise to find him again. So, Charles is released but he's forced to pair up with a genius code-breaking chicken called Gertrude for the mission. He needs her if he's going to rescue his cousin from the enemy - but will he be able to control his appetite?!

Featuring the cunning French Resistance, a castle break-in and a race against time to stop plans falling into the wrong hands, this wartime tail will make you laugh and cry - and maybe teach you a thing or two as well!
