In his book "22 Cells in Nuremberg," Douglas Kelley details his personal accounts of interactions with the Nazis on trial at Nuremberg. In the final chapter, he details how the events of pre-WWII Germany could occur in the modern United States.

Much of his research is available in the UC Berkeley libraries.
