Jacky begins to market her own patent medicine consisting of an alcoholic tincture of opium (better known as laudanum) and Kentucky bourbon, which she markets during medicine shows. Most patent medicines of the time were made up with similar ingredients and similar lavish claims for their efficacy. Use of these compounds was widespread and unregulated.

The crew encounter a secret abolitionist running a slave-selling scam in which the "slave" is sold, and then escapes to be sold again and again. Similar plots were sometimes used to trick runaways into cooperating with a sale which would turn out to be final. After the import of foreign slaves was forbidden, the demand for slaves became very high and numerous types of deceit and slave-stealing became common. Jacky's crew encounters a family of rogues who make their living trying to repossess escaped slaves in the fashion of Patty Cannon.

Jacky herself attempts to pass for quadroon or octoroon as a disguise at one point, in an inversion of the usual trick, which was to pass people who were an eighth or a quarter African heritage as white. Several times, Jacky reflects on the diversity of her crew, which includes Native Americans, Africans and African-Americans, American Appalachians, British such as herself and her butler (or First Mate) Higgins, and so on. This reflects the reality of pirate crews of the day, which often contained escaped black slaves.

• Mike Fink was a real keelboater, reputed to tell tall tales.
• The Lafitte brothers were real pirates, and as Meyer has a subsidiary character note as Jacky's crew approaches New Orleans, Jean Lafitte made most of his money as a fence of stolen goods and a source of illegally imported slaves.
• Near the end of the book, an adopted white Shawnee called Lightfoot, a rifleman who always travels with his native Shawnee "brother," reveals his white surname to be "Bumpus" in an obvious tribute to James Fenimore Cooper's Natty Bumppo.
• Crow Jane's niece might be a reference to Sacajawea, as she "has been on that Lewis and Clark Expedition across the new Louisiana Territiory".
