Black Cross by Greg Iles is an action novel set in World War II. Its protagonist is an American pacifist, Mark McConnell, who is a doctor and chemical engineer specializing in nerve chemical/biological weapons and who is working for the duration of the war in Oxford, England. His sidekick is Jonas Stern, a Jewish refugee. They are assigned a mission by British Brigadier Duff Smith against a German prisoner camp, Totenhausen, where two powerful nerve gases, Sarin and Soman, are being produced. Their highly improbable mission is to use Britain's own supply of Sarin to kill everyone in the camp, inmates included. It turns out, by some odd coincidence, that Jonas' father Avram is being held at the camp. Mark and Jonas work with Avram and a few other prisoners to successfully save many of the inmates and destroy the camp. After Mark dies in an accident, his grandson narrates the story.
