Explanation:

According to a different source, this is the paragraph the question refers to:

It may seem surprising that no Confederate sympathizers took action against Van Lew, given her strong and public views on secession and slavery. Surely there were suspicions, especially among her upper-crust neighbors, but the matter never went beyond those suspicions. Historians have suggested that the secessionists were victims of their own cultural bias, believing that no aristocratic person, and certainly not a lady, would ever consider taking part in anything as impolite as spying. A true lady managed her servants, prepared parties and gatherings, and blindly supported her husband. Such attitudes worked in Van Lew's favor, diverting suspicion from her.

In this paragraph, we learn of the way in which people tended to think about ladies, and in particular, aristocratic ladies. We learn that most people did not believe that polite ladies of society would be capable of becoming involved in something like spying. This appeared to be a contradiction that was unimaginable. Because of this, no one suspected Elizabeth Van Lew, allowing her to do a better job as a spy.
