Chapter 10: Just ahead, at the edge of the stream, Denver could see her silhouette, standing barefoot in the water, liking her black skirts up above her calves, the beautiful head lowered in rapt attention.
Chapter 13: When he saw Denver silhouetted in the lamplight at the window, he could not help thinking, “And whose ally you?”
