My Secret Life in Hut Six: One woman's experiences at Bletchley Park

Born and brought up in the sheltered environment of the Welsh valleys, Mair Thomas is amazed to discover her grasp of the German language and musical training make her an ideal code-breaker for Bletchley Park, and she finds herself working long shifts in Hut Six. Sworn to secrecy, she is so afraid of blurting out something she shouldn’t, she cannot sleep, especially not when her landlord tells her he will stand outside her room, listening. Ironically the man she loves is a pacifist, while her aunts think she should be at home, looking after her father.
