The start of a thrilling new mystery series from the number-one-bestselling， award-winning author of Murder Most Unladylike。

Britain is at war， and a secret arm of the British government called the Ministry of Unladylike Activity is training up spies。 And who better to become a spy than a child？ A child can go places， see things and listen in on conversations in a way that no adult ever can。

And then the murder happens。。。
