the following statement is not true. It is not Eulalia who discovers the revolt, but the woman working at the jail who overhears 2 slaves talking about it. Furthermore, the plot is not made up by local abolitionists, but by Brainard (who's from the North) 

 As time passes, Eulalia also discovers a plot by a group of local abolitionists to stage a large-scale slave rebellion, with aims to "free" the otherwise-content slaves of the plantation, and to murder both Moreland and Eulalia, despite their kindness to their slaves.
