Almost above a score of the lights, Hal shut off the motor and the machine began to descend. A short time later it came quietly to earth just beyond the village. Hal scrambled out and spoke to the Germans. "This should be Spa, according to my calculations," he said. "Correct me if I am wrong." "You are right, sir," said one of the German delegates. "You have done well in bringing us here in such a short period of time." The Germans alighted, and Chester also scrambled out. "If you will come with us," said the spokesman of the enemy mission to the lads, "we will see that you are provided with quarters for the night. It is hardly possible that we will return before to-morrow at noon, if at all." The lads followed the Germans into the town. Before a building somewhat larger than the rest, the men stopped and the one who appeared to be leader of the party said: "You gentlemen wait here. I will go within and see that quarters are provided for the young Americans." He motioned the lads to follow him, which they did. Inside a German officer barred their progress, but the German soon set the man’s doubts at rest, and the latter stepped aside. "Captain," said the German envoy, "these gentlemen have brought us back from the allied lines, and will conduct us there again to-morrow should it be necessary for us to go. You will kindly see that they have all necessary accommodations for the night." "Yes, sir," said the captain. "Then I shall leave them to you. I will return for them to-morrow some time." "Very well, sir." The German bade the lads good night and took his departure. The German captain addressed them. "Kindly follow me, sirs," he said. The lads did so. Along a long hall they were led. Then they turned into a large room at the far end of the hall. Inside were a dozen or more German officers. The captain led the way toward a door across the room. All eyes were turned on the lads as they stepped across the room. Suddenly there came an exclamation from a man who sat near, as Hal and Chester passed. A chair scraped the floor and a man sprang up and confronted them. Hal and Chester looked into the eyes of General Knoff, the German general whose daughter Chester had befriended in Sedan some weeks before. "So," said the general confronting the lads with a gleam of anger in his eyes, but his gaze resting particularly upon Hal, "so you made fools of me in Sedan, eh?" Hal smiled. He was perfectly safe now and he knew it. Not a man there nor in the German lines any place for that matter would dare harm the officer who had piloted the German envoys back from their tryst with Marshal Foch. "It had to be done, General," said Hal, still smiling. "But," protested the general, "why was it necessary for you to pick me for your tool?" "We wouldn’t have done that, General," said Hal, "had you not been so insistent upon our having breakfast with you."
