Let's see the story of Mary Bowser become a movie!

\Mary Bowser, former slave of the Van Lew family, infiltrated the Confederacy by working as a servant in the household of Jefferson Davis. Bowser was assumed to be illiterate, and as a black woman was below suspicion. Practically invisible, she was able to listen to conversations between Confederate officials and read sensitive documents, gathering information that she handed over to the Union.
