Two hundred years ago, a man hid a fortune and left behind three encrypted letters. No one has cracked them until now.
A 200‑year‑old cipher hides a secret that could reshape the world. When a legendary set of encrypted letters finally begins to yield its secrets, British Museum curator and codebreaker Calla Cress is framed for the disappearance and murder of her best friend. Forced on the run, she must decode the Beale Ciphers and stop a vengeful foe before the codes unleash a plan that threatens civilisation.
What if the world’s greatest cipher wasn’t about gold but about power?
When Calla Cress and her friend Jack Kleve discover ancient wall paintings and a mysterious telescope in a New Mexico cave, they realise the Beale Ciphers might be more than a legend.
Moments later the cave collapses, Jack disappears, and Calla becomes the prime suspect in his murder. Discredited and on the run, she travels to North Africa following Jack’s clues and encounters mercenaries, treasure hunters and a vengeful foe with a deadly plan for the ciphers.
Haunted by a recent loss and hunted by her own government, Calla must trust Halona Osa‑Menglian, a descendant of the Wampanoag people and guardian of the telescope, and decode a centuries‑old number sequence painted by her ancestors.
From sacred caves and desert hideouts to Moroccan souks and secret intelligence offices, the chase becomes a race against time to prevent a plan that could unleash chaos.
Fans of Steve Berry, Clive Cussler and Jason Bourne will devour this high‑stakes techno‑thriller where history, cryptography and espionage collide.
The legend of the Beale Ciphers is one of America’s enduring mysteries: three encrypted letters said to point to a hidden treasure in Virginia. In The Decrypter and The Beale Ciphers, author Rose Sandy reimagines what would happen if the code were finally cracked – and if its secrets were far more dangerous than gold. This blog post explores the novel’s themes, tropes and exotic locations.

The Decrypter and the Beale Cipers is an enjoyable read. Calla, Jack, and Nash must work alone this time. Calla must decipher the Beale papers, Nash must go on a mission of his own to help an friend, and Jack is kidnapped. Eventually the plot reveals that all events are related and other characters come in to play in order to get the three back together where they belong. I really liked this book and the entire series. Even though the books can be read as stand alones, I think it's better to have read each previous book as there are references to other characters and events that might be a bit confusing. Definitely recommend the series.
