Bletchley Park Mystery

Twelve-year-old Robyn has grown up in Bletchley Park, where her father works as a driver. When she's not at school, she helps her dad in the garages. Then the war begins and everything at Bletchley changes. Robyn is assigned to help with the carrier pigeons that take messages to the Allies. But first, she must sign the Official Secrets Act and is ordered not to leave the grounds of the park. While Bletchley is buzzing with people recruited for the war effort and all eyes are on the skies, Robyn becomes convinced that there's something sinister going on within Bletchley Park.

Before the war starts, Ned is resigned to a future working in the family funeral parlour. Then the covert operations at Bletchley Park begin and his life is transformed. Ned and his mother leave Bletchley Park on a vital wartime mission into the remote Welsh countryside. Their task: to protect the priceless artwork that is being stored in a slate mine in the village of Manod. As long as its whereabouts are secret, they'll keep the national treasures out of the hands of the enemy. But when it appears that someone in the village is trying to expose the truth, suspicion turns to the newcomers.
