Frank had reasoned quickly. He had been sure that the next move of the German officer would have been to denounce him also. But while the German officer had had a good look at Henri on the night of the Zeppelin disaster, he had not seen Frank. Frank had been in the shadow when the officer had tried to murder Henri; he had taken the German by surprise, and stunned him. And so there was no way in which the German could know him again, unless he saw him with Henri and so leaped to the conclusion that he must also have been with him on the night of disaster. By that process of reasoning Frank argued that he might remain free to go about the town. The Germans had come to trust the Boy Scouts, understanding that their honor was pledged when they gave their word, even to an enemy. Some of the restrictions applying to the other citizens of Amiens did not restrain them. They were allowed to be on the streets after the hour of curfew, for one thing. And between the scouts and a good many of the German privates and younger officers a relation almost friendly had been established. Frank, for instance, was welcomed at one Bavarian mess, which contained several soldiers who had studied at English schools, and liked a chance to air their knowledge of the English tongue. He hoped to gain some information in this way. Nor was he wrong. His friends had heard of the arrest of Henri, who, like Frank, was popular with them. And it turned out that they had little use for the officer who had caused the arrest. He was known as a tyrant who had more than once during the campaign shot down his own men for slight breaches of discipline. Frank learned that he had been degraded for the destruction of the Zeppelins, for which he had been held responsible. His superiors had scouted his story of two boys who had burned the dirigibles, and had assumed that he had been careless. Therefore Frank found it easy to discover where Henri was confined. He was to be tried by court-martial early in the morning, and for the night he was in a room on the ground floor of the Hotel de Ville. "He's only a boy," said a Bavarian corporal. "No need to guard him closely. Even if he escaped, where could he go? Our men are everywhere."
