Wartime.

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?



Follows two young women, Pearl and Ellen, who are recruited
to work at Bletchley Park during the Second World War

Set in atmospheric 1940s England, The Secrets
Act also explores serious historical themes
