It’s tricky to know where to begin – there’s so much excitement with murders, codes, and spies that the story is already twisting itself up! It’s December 1941, just before Christmas, when a bomb strikes Deepdean School for Girls. May and Nuala quickly leave the chaos to stay with May’s sister Hazel Wong, who works at Bletchley Park. Almost immediately, they’re thrown into a thrilling mystery: a codebreaker’s “accidental” death hides a secret message that could mean he was a spy. With Daisy’s brother Bertie blamed, May, Nuala, and Eric must unravel the truth in this puzzling, secretive world full of clever minds.
