"Do not speak," he said in a clear voice that made Dawson's heart leap with joy. "Just listen to me, because I cannot last long. I know it--inside. I failed, but perhaps it is not too late. Perhaps you will succeed. You must. Listen to me! Ten miles along the Duisburg-Dortmund highway there is a little group of hills. They form a ring, and the valley in the middle is flat as a table. You cannot see it from the air because it is perfectly camouflaged. The spot has never been bombed because it is out in the country. Our bombers wouldn't give it a second look. "But it _is_ a military objective. The most important this moment in all Germany. In that camouflaged valley there are a hundred British and American heavy bombers. Yes! British and American heavy bombers, I tell you. I have seen them. For months the Nazis have been planning this blow. They call it their secret weapon. It came out of the mad brain of the one they call Herr Baron. Who he is no one seems to know. But it is rumored that he was a famous Luftwaffe pilot shot down in the Battle of Britain. That he was horribly burned about the face. But he lived, and became the man of many faces. Some say he was a great actor before the war. I do not know. But I have seen him many times, and every time he looked different. Once I was almost able to kill him, but I failed then, too. To think, if I had only succeeded, this terrible thing might not be hanging over England, as it is." The man stopped talking and stark terror gripped Dawson and Farmer again. But the man only paused to draw breath into his dying body. He went on speaking again, a wild light flaring up in his eyes.
