Both Harriet Jacobs and her brother John frustrate the threats of their master by simply choosing what was meant as a threat: When Dr. Norcom throws John into the jail, which regularly serves as the place to guard slaves that are to be sold, John sends a slave trader to his master telling him he wants to be sold. When Norcom tells Harriet to choose between becoming his concubine and going to the plantation, she chooses the latter, knowing that plantation slaves are even worse off than town slaves.
