The secrets of the mysterious Culper Spy Ring
The Culper Ring, one of America's first 'spy families', played an influential role in the American Revolution, yet their identities remained a mystery for centuries.
Gathering information for George Washington, a group of seemingly ordinary citizens - a farmer, a whaleboat captain, a pub landlord and a merchant - not only helped turn the tide of the war, but also shaped the world of espionage we know today.
