Your Mission: Find Mary's secret diary using spycraft stools to
uncover hidden codes!
It's a true story of bravery: Mary Bowser was an African American spy
for the Union who worked as a maid in the mansion of Confederate
Jefferson Davis. From hair-raising close calls when she almost gets
caught to how she uses her photographic memory to "steal" top secret
documents. Mary's story reads like a gripping novel.
It's a mystery to solve: There are clues embedded in the story's
text and illustrations, and Spycraft materials--including a replica
Civil War cipher wheel--come in an envelope at the beginning of the
book. Use both to discover what happened to Mary Bowser's secret
diary.
