Who Was The FEMALE Spy Who Changed The Course Of The American Revolution?

In the middle of the American Revolution, there was a spy so secret we still don’t know her name, only her code: Agent 355. Moving through British‑occupied New York as a well‑placed “lady,” she is said to have charmed information out of officers, slipped secrets to the Culper Ring, and helped expose Benedict Arnold’s treason, then vanished into history with no confirmed face, no confirmed grave, and a legend built entirely out of whispers in other people’s letters.
