The Rose Code

1940: As England prepares to battle the Nazis, three very different women heed the call to the enigmatic rural estate Bletchley Park, where Britain's brightest minds train to break German military codes. Osla, the vivacious debutante, has it all—beauty, fortune, and the dashing Prince Philip of Greece sending her roses—but she is determined to show herself as more than a social girl, and uses her fluent German as a translator of intercepted enemy secrets.

Mab, the haughty self-made product of east-end London poverty, operates the famed codebreaking machines while concealing ancient scars and looking for a socially suitable marriage. Both Osla and Mab see potential in local village spinster Beth, whose timidity hides a tremendous ability with riddles, and Beth soon spread her wings as one of the Park's few female cryptanalysts. War, grief, and the unbearable burden of secret, however, will rip the three apart.

1947: As the royal wedding of Princess Elizabeth and Prince Philip erupts in post-war Britain, three friends-turned-enemies are reunited by a mystery encrypted letter, the key to which is hidden in the long-ago treachery that shattered their friendship and sent one of them to an institution. A mystery traitor has resurfaced from the shadows of their Bletchley Park past, and Osla, Mab, and Beth must rebuild their old partnership in order to break one final code together.
