In Dark Mural Nicole says, "My office on the third floor of Arts Humanities had a window overlooking the downward slope of a wooded hillside. Sitting at my desk, I saw some pale yellow spots among the wave of green treetops, my first glimpse of autumn color."
This photo gives an example of the kind of scene she describes. The people seen as tiny figures on the sidewalk suggest the grand scale of such vistas on a campus in the Appalachian foothills.
Since this was taken in springtime, as shown by sparse foliage on the trees, it gives a better impression of what Nicole would see from her window in Dark Picasso, the third Nicole Tang Noonan mystery, which takes place in April. Dark Picasso will be published in January, 2019.
In fact, I took this picture on the campus of Ohio University, in Athens, Ohio (not to be confused with Ohio State University in Columbus, Ohio), near the border with West Virginia. The fictional location of the Nicole Tang Noonan mysteries is somewhere between Chillicothe and Athens, so the landscape would be similar.
