Luckily it was growing dark and Tom had pulled Rabig's hat well down over his face, yet not so far as to make it appear that he was trying to evade scrutiny. He walked on briskly to a point where a sentry on duty before an opening in the wire fence was standing.
"Halt! Wer da?" hailed the sentry.
"Ein Freund," replied Tom.
"Losung."
"Potsdam."
At the same time Tom carelessly extended the pass which the sentry glanced at and returned to him with a curt gesture, in which Tom thought he saw contempt. But it meant that he was free to pass, and he did so with an air of indifference.
His heart was beating so fast that it seemed as if he would suffocate. At every step he feared to hear a shout behind him that would tell him that the ruse was discovered. But the fortune that had frowned upon him so many times of late this time was friendly. Behind him were the usual camp noises and nothing more.
In a few minutes he had gotten out of sight of the lines and was in the woods at a point where the trees grew thickly and only a half-beaten trail led through the underbrush. Then he quickened his pace and soon found himself running.
If he were pursued, he had fully made up his mind what he would do. He would never again see the inside of a German prison. He had the revolver and he would fight to the last breath. He might go down, probably would, considering the odds that there would be against him, but he would die fighting, and would take one or more of his enemies with him.
He was racing along now at top speed and he only slackened his gait when he knew that he had put miles behind him. By that time it had grown wholly dark, and in the woods it was as black as pitch. He was safe for that night at least. His enemies could not have seen him if they had been within ten feet of him.
