Flat Lake in Winter — Joseph T. Klempner

Deep in the heart of the Adirondack Mountains sits a mansion, its image reflected perfectly on the still water of Flat Lake.

Now Fielder must fight the prosecution's campaign for the death penalty, but as he scours Jonathan's past for anything that will help their case, he uncovers a cache of dark family secrets that turn the case in a shocking and unexpected new direction...
