Simeon, a free black man, is working on the construction of the White House, as a bricklayer. While he daydreams about a quiet life after this job, perhaps meeting a nice woman and settling down to have children, his friends Eugene and Clifford are not so lucky. They are slaves, on loan from their master, and will have to return to Virginia when this project is over. The speculative element of this story comes from what they decide to do to avoid that fate.
Simeon is a quietly perceptive narrator, but he can not see everything. Because the story is told through his point-of-view, we never find out exactly what Eugene and Clifford did or who they struck their bargain with. That uncertainty provides the impetus for Simeon to write down this story.
Juxtaposing the White House – symbol and seat of the U.S. government – with the reality of slavery, is a bold and decisive move. It forces the reader to confront just whose labor built so many of our monuments, all while telling an emotionally compelling story.
