The Rose Code

by Kate Quinn

(£14.99, Harper Collins, HB)

Three very different women are recruited in 1940 to Bletchley Park, top-secret home of the codebreakers. Socialite Osla; ambitious Mab; and shy, smart Beth are friends, until an act of betrayal tears them apart. Years later, on the eve of a royal wedding they are brought together to crack one last code. Weaving real-life and fiction, Quinn’s storytelling is compelling and masterful.
