A groan escaped the wretched sentry. Ever since he had exchanged words with Dick, he had been conjuring up all sorts of pains and penalties as a consequence of his rashness. His knees positively knocked together as he besought this officer to spare him and forget the matter.

"Release them at once," cried Dick peremptorily. "Now, listen. If His Highness asks no questions, well and good. Perhaps we shall not be too late for this discussion even now, that is if you hasten. As to the third officer, hold him till you receive a written order, or till an hour has passed. Now, stand aside. Major, please follow."

"But—but you don't mean to tell me that you have obtained our release?" cried that astonished officer. "How? And where are we to go?"

"Please follow as if you had every right to be at liberty," answered Dick. "I'll tell you later how I've worked it. But come at once, for there is no saying when other soldiers may turn up, with perhaps an officer."

He stalked before them out of the guard-house and led the way into the streets of Adrianople, streets for the most part still untenanted. For civilians lay at home shivering beneath the cruel bombardment, and fearful of those dreadful shells. They were coming again into the city, and more than once Dick and the two who followed had to dodge behind some building to escape the bursting of a bomb.

"And now, perhaps, you'll tell us where we are going," said the Major, when they had gained a smaller street. "To the airship? Impossible. She would never dare to come here in daylight. Then where?"

"To join Commander Jackson and Alec," answered Dick. "We entered the city last night in search of you both. But—hush! Lookout! Let's hurry. If that isn't the very fellow I most wanted to avoid."

A figure had dived into the street immediately behind them, a figure strangely familiar. Dick eyed him suspiciously, and then recognized him with a start. For this man's head was swathed in bandages which left his face fully exposed, and that face was young, and smooth, and hairless. In fact, it was the very officer against whom he had collided on the previous night.

"Had he been back to his house and there discovered Alec and the Commander? Or was he now on his way?"

Dick asked himself those urgent questions, and then, spurred on by fear and dreadful foreboding hastened along the street, the Major and his friend close beside him, and the inquisitive officer in rear. Soon they turned into the street in which that house they sought was located, and for a moment the follower was out of sight.
