I've already posted a map of Fuchs College and a map of Blanton, Ohio. These are fictional places where most of the action in the Nicole Tang Noonan mysteries takes place. This map shows the spatial relation of the college and the town.
I imagined a rural campus located about ten minutes by car from the nearest town. The dotted line indicates a footpath across an open field. Students use it as a shortcut for walking into town. This is central to the plot of Dark Mural, the first book in the series.
The road shown in the upper-left corner crosses a creek and leads to Chillicothe, the only real place indicated on these maps. This fictional road would take the driver to the real route 35.
This area of Ohio is in the foothills of the Appalachian mountains, very pretty country with winding roads through wooded hillsides. The land further south flattens out. It would have been farmed by the first Europeans to arrive here, who were English.
The German settlers who came later would have made do with the steeper land. In my imaginary history, they formed a commune, as was frequently done in the mid-1800s. By the late 1800s, their descendents left communal life, sold some of the land, and devoted the rest to establishing the Eden Independent School, which later became Fuchs college.
