Mr. Liebling’s evocative photographs . . . effectively capture the spirit of the two houses. They focus on poignant images like a light-struck glass knob at the Homestead, which casts ghostly reflections on a white door; worn stone steps in Emily’s garden; her plain white dress, preserved in a glass case; a nest of scuffed children’s shoes stored at the Evergreens; and the long march of picket fence along Main Street-now gone-that once united the two homes.
