It is April 1845. You are abolitionist activist Frederick Douglass. You have completed the first draft of your biography, Narrative of the Life of Frederick Douglass, an American Slave. You mail it to the Anti-Slavery Society in Boston for publication.

They write back wanting to verify that you are who you say you are. They ask for 5 codes that will prove you are Frederick Douglass. You better determine the codes or your story will never reach the American people.

Make sure you know about Frederick Douglass to crack the codes and get it published!
