"The whole place is burning! Get out!" he cried, in German. "There may be explosive spirits still down there!" He slammed the door shut, and Frank heard running footsteps above. He waited until there were no more, and then, almost overcome by the smoke, slipped through the door. No one was left in the hallway into which he came. The place was full of smoke. He did not venture to the front door by which he had entered, but, still dragging his can of petrol, went to the back. Going through the kitchen, he found another door, as he had been sure he would and in a moment he was drinking in the cool, fresh air. The rain that was beating down on him now was welcome. Just as he reached the open there was a sharp explosion behind him, and he looked back, to see the windows on the ground floor glowing. That was the other can of petrol, as he could guess readily enough. At once he ducked, and, running low, got well to one side of the house. Then, just as a great burst of flame lighted up the whole scene, he dropped to the ground, and lay peering toward the road in front of the inn. A dozen officers and as many men, all in the German uniform, with the spiked helmets that made them so unmistakable, were in the road, staring at the burning house. And it was not until Frank saw how angry one of the officers was that he realized what a useful idea his had really been. Now detection of the Germans was certain. Investigation was almost certain to be made of a fire in a building so far out of the range of the German artillery as this. And so, even if neither he nor Captain Greene got back in time, the torch he had lighted, meaning only to secure his own escape, was likely to prove a death blow to the German hopes of secrecy. Frank could not hear what the Germans were saying, but he had no intention of getting closer in an attempt to do so. Instead, having satisfied himself that there were no pickets behind the burning inn, he began crawling cautiously to the rear. It was a difficult task, especially so because of the petrol, which was no light burden. But he managed to get well out of the lighted zone and then he decided that it would be safe to straighten up and walk along. As he went along the burning building served him well. It gave him a fixed landmark from which he could lay his course to the spot where he had left the monoplane and Captain Greene. By looking back from time to time he could correct his course, when he was crossing fields. And so without the guidance of roads, and partly to make better time and partly to avoid stray German pickets, he chose to stay away almost entirely from the roads and go across country.
