The Ministry of Unladylike Activity

1940. The world is at war, and a secret arm of the British government is training up spies.
Enter May Wong: courageous, stubborn, and desperate for the war to end so she can go home to Hong Kong (and leave her annoying school, Deepdean, behind forever). May knows she would make the perfect spy. After all, grown-ups always underestimate children like her.
When May and her friend Eric are turned away by the Ministry, they decide to take matters into their own hands. Masquerading as evacuees, they travel to Elysium Hall, home to the wealthy Verey family - including snobby, dramatic Nuala. They suspect one of the Vereys is secretly passing on information to Germany. If they can prove it the Ministry will have to take them on.
But there are more secrets at Elysium Hall than either May or Eric could ever have imagined.
And the someone is murdered...
