The 39 Clues: The Cahill Files: Spymasters

This collection gathers three short adventures from the Cahill family's secret archive, first released as separate ebooks. The Cahills, a clan that has quietly shaped world events for centuries, appear at three turning points in history. In one tale, a young family member must escape from the capital while it burns during the War of 1812. Another follows a daring attempt to uncover the hidden method behind a famous magician's escape. The last sends a young Cahill stowing away on a risky mission aboard an early nuclear submarine. Each story pulls back the curtain on the family's influence, and the book invites readers to step into the vault, with a warning that the secrets inside may be more than they bargained for.
