The Scavengers of Graveny Marsh

They operate from "The Pit," a secret room beneath the ancient stone stables of Whitstable Castle. This team of experts feeds phony intelligence to the Germans. But Captain Janine Carlisle discovers a frightening secret - a fifth column who call themselves the Scavengers of Graveny Marsh have stumbled upon secret Allied plans for a swimming tank - the Duplex Drive Sherman - ready to go ashore in the first wave of the invasion. Carlisle must stop them before the plans can reach German command. But she learns the Scavengers are planning a diversion - to assassinate General George Patton on the eve of D-Day as he speaks to the troops in nearby Seasalter and in the chaos spirit the plans across the English Channel. Carlisle learns of the plot just as Patton steps to the podium to give "The Speech." The fate of D-Day hangs by a thread with only minutes to spare.
