The 39 Clues: The Cahill Files: Spymasters

In 1814, redcoats burned the White House to the ground. In 1889, Harry Houdini discovered a trick that would save his life. In 1955, the U.S. launched the world's first nuclear submarine. And one family pulled the strings behind the scenes at each of these events: the Cahills, the most powerful family the world has ever known.

Now the Cahills have opened their vault and secrets are pouring out. This book contains three of them, three stories that will change history as we know it forever. Flee alongside a young Cahill as Washington burns, unlock Houdini's magic, and stow away with young Fiske Cahill on a desperate mission that could cost his life.

Venture into the vault if you dare. But don't say we didn't warn you.

Available in a single edition for the first time, this bind-up contains the three Cahill Files shorts, originally published as e-books:

• The 39 Clues: The Cahill Files Book 2: The Submarine Job
• The 39 Clues: The Cahill Files Book 3: The Redcoat Chase
• The 39 Clues: The Cahill Files Book 4: The Houdini Escape
