Veteran journalist and author Joseph C. Goulden offers a good review of John A. Nagy's Dr. Benjamin Church, Spy: A Case of Espionage on the Eve of the American Revolution.
No less an authority than the American Revolution historian Thomas Fleming calls Dr. Benjamin Samuel Church Jr. “the least known and most dangerous spy in American history.”
Surely he was in a position to do grave harm to the fight for independence from the British. As John Nagy writes, Church was “one of the most admired and respected patriots in Massachusetts,” on a par with John and Samuel Adams and John Hitchcock. He served “on almost every committee of importance” and was the on-site political leader in the state.
In terms of position, Church inarguably was the most important American spy ever, for his treachery could have led to the loss of the war that created the United States. By comparison, such spies as Alger Hiss of the State Department, Aldrich Ames of the CIA and Robert Hanssen of the FBI were mere spear-carriers.
