I have the Sam Davis book, and have "Spies of the Confederacy" ordered, but was looking to see if there were any others.

On a side note, one of the names we had picked out for a son was Sam Davis Roberts. While in Pulaski, I visited (again) the monument on the courthouse square, the museum where he was hung, and the capture side at Minor Hill. On my next trip to the area, I will try to visit the Schuler House in Campbellsville, as it was a "safe house" for Coleman's Scouts.
