The thrilling brand-new mystery from the million-copy-bestselling author of Murder Most Unladylike.

'Robin Stevens is Agatha Christie for children' - Katherine Rundell

'It's hard to know where to start. There's so much to say - about the murders, and the codes, and the spy, that I'm getting tangled up in the story already...'

It's December 1941, and almost Christmas, when a bomb falls on Deepdean School for Girls. May and Nuala are whisked away from the chaos and sent to stay with May's big sister, Hazel Wong, who is working at Bletchley Park.

Within seconds, they're thrown straight into their most dangerous and difficult case yet. A codebreaker has been shot in what first appears to be a tragic accident - until a suspicious and top-secret message is discovered in his pocket. Was he a spy, working for the other side? Was the message planted on him? Most importantly - was this murder?

Worst of all, Daisy's big brother, Bertie Wells, is being blamed. It's up to May, Nuala and their friend Eric to prove Bertie's innocence and solve the mystery. But Bletchley is a strange and secretive place, full of Britain's most ingenious minds. They'll need to watch, listen, and puzzle out the incredible, unthinkable truth...

About the Author

Robin Stevens was born in California and grew up in an Oxford college, across the road from the house where Alice in Wonderland lived. She has been making up stories all her life. When she was twelve, her father handed her a copy of The Murder of Roger Ackroyd and she realised that she wanted to be either Hercule Poirot or Agatha Christie when she grew up. She spent her teenage years at Cheltenham Ladies' College, reading a lot of murder mysteries and hoping that she'd get the chance to do some detecting herself (she didn't). She went to university, where she studied crime fiction, and then she worked at a children's publisher. Robin is now a full-time author and the creator of the internationally award-winning and bestselling Murder Most Unladylike series, starring Daisy Wells and Hazel Wong, and the brand-new Ministry of Unladylike Activity. She still hopes she might get the chance to do some detecting of her own one day. She lives in England.
