What is main idea of "Night Talkers"?

"Night Talkers" is a story based on life and personal
beliefs in Haiti, as contrasted with the less personal relationships of those in
America, centered on New York. On the island, communication between close relatives
takes place on a non-verbal level, the level of "night talkers." Thus the impending
death of Estina is somehow made known to the main male character, Dany, who travels from
the United States to Haiti to be with her in her final hours. It is as though Estina
intuitively knows that Dany is thinking about carrying out a violent act of vengeance,
and silently summons him back to Haiti to prevent him from doing so. As one of the major
characters says, "Blood calls blood. She [Estina] made him come so he could see her
before she died" (paragraph 160.)
