When George Washington beat a hasty retreat from New York City in August 1776, many thought the American Revolution might soon be over. Instead, Washington rallied - thanks in large part to a little-known, top-secret group called the Culper Spy Ring. He realised that he couldn't defeat the British with military might, so he recruited a sophisticated and deeply secretive intelligence network to infiltrate New York. Drawing on extensive research, Brian Kilmeade and Don Yaeger have offered fascinating portraits of these spies: a reserved Quaker merchant, a tavern keeper, a brash young longshoreman, a curmudgeonly Long Island bachelor, a coffeehouse owner and a mysterious woman. Long unrecognised, the secret six are finally receiving their due among the pantheon of American heroes. *Now with a new afterword containing never-before-seen research on the identity of the spy ring's most secret member, Agent 355 "This is my kind of history book. Get ready. Here's the action." -BRAD MELTZER, bestselling author of The Fifth Assassin and host of Decoded
