Recently finished a novel of that title by Ben Haas. It was copyrighted in 1964, a novel about a mythical Southern State and a Negro's struggle for civil rights amid the culture of a persisting Confederacy. Structurally it is like War and Peace in that you are in the life of the various characters successively with bridging description of events from a narrator's position. Charming and thought provoking. I got the above novel at the Salvation Army which is in part a reference for where the local culture has been.
Now that Ron Rosenbaum has written on Valkyrie, I recall 'Plotting Hitler's Death' by Joachim Fest. A great book. That one I took to Half Price books for nothing.
