"The Last Station" was adapted from the novel by Jay Parini, and its structure is fairly intricate parallel love stories (Tolstoy and Sofya, Valentin and Masha), plus interlocking triangles (Sofya and Chertkov contending for Tolstoy's soul, Sofya and Chertkov pumping Valentin for information about one another's grip on Tolstoy's property).
