The first book in the Sgt. Dunn Novel series. When Allied intelligence agencies discover the Nazis will complete construction of their atomic bomb before the summer of '44 is out, the race is on to destroy the German facility before the course of the war takes a terrifying turn.

Operation Devil's Fire begins two weeks before D-Day with two seemingly unrelated events: a British spy, working in Berlin, steals a top-secret memorandum and is terrified by its contents. Two days, later a P-51 Mustang pilot spots a new German jet bomber while on B-17 escort duty over Germany.

When American and British intelligence link the events, there is one inescapable conclusion: Germany will finish the atomic bomb first and, furthermore, possesses a new transatlantic jet bomber.

U.S. Army Ranger Sergeant Thomas Dunn and his British Commando rival, Sergeant Malcolm Saunders, receive top secret orders from President Roosevelt and Prime Minister Churchill. Their teams of rugged, lethal soldiers will fly into Germany. Their missions: destroy the German atomic bomb facility and the new jet bomber.

Failure means the invasion of Europe was all for nothing. If Hitler drops the atomic weapon on the United States, Roosevelt and Churchill will have no choice but to concede the European continent to the dictator.

While the President and Prime Minister wait and worry, the two elite teams fight against enormous odds to complete the missions and return safely home.
