The secrets act /
Weatherby, Alison,author.
Pearl and Ellen work at top-secret codebreaking HQ, Bletchley Park.   Pearl is the youngest. A messenger at sixteen, she's untidy, lively, bright, and half in love with the wrong boy, Richard. Her circle of friends overlaps with his - the dashing young men on their motorcycles who courier the secrets that Bletchley deciphers.   Ellen is a codebreaker. Reserved, analytical and beautiful. She never expected to get close to a girl like Pearl - or fall for a chap like Dennis.   But when tragedy strikes, their logical world is upended, with both friends caught in a spy plot that rocks the very heart of the war effort. Who can they turn to now? Who can they trust? And above all, can they unmask the traitor in their midst before it's too late?
