Not only was Carg puzzled by this strange summons but none of the others could understand it. The Belgian, when questioned, merely shook his head. He was not the general's confidant, but his fee as messenger would enable him to buy bread for his family and he had been chosen because he knew the way to the hospital ship.
As there was nothing to do but obey, the captain went ashore in one of the launches, which towed the skiff in which Maurie had come.
When he had gone, Lieutenant Elbl, who had been sitting in the cabin, bade the others good night and retired to his room. Most of the others retired early, but Patsy, Uncle John and Doctor Gys decided to sit up and await the return of the captain. It was an exceptionally cool evening and the warmth of the forward cabin was very agreeable.
Midnight had arrived when the captain's launch finally drew up to the side and Carg came hastening into the cabin. His agitated manner was so unusual that the three watchers with one accord sprang to their feet with inquiring looks.
"Where's Elbl?" asked the captain sharply.
"Gone to bed," said Uncle John.
"When?"
"Hours ago. I think he missed your society and was rather broken up over the necessity of leaving us to-morrow."
Without hesitation Carg turned on his heel and hastened aft. They followed him in a wondering group. Reaching the German's stateroom the captain threw open the door and found it vacant.
"Humph!" he exclaimed. "I suspected the truth when I found our launch was gone."
"Which launch?" asked Uncle John, bewildered.
"The one I left with the ship. On my return, just now, I discovered it was not at its moorings. Someone has stolen it."
They stared at him in amazement.
"Wasn't the deck patrolled?" asked Patsy, the first to recover.
"We don't set a watch till ten-thirty. It wasn't considered necessary. But I had no suspicion of the trick Elbl has played on me to-night," he added with a groan. Their voices had aroused others. Ajo came out of his room, enveloped in a heavy bathrobe, and soon after Maud and Beth joined them.
"What's up?" demanded the boy.
"The German has tricked us and made his escape," quietly answered Dr. Gys. "For my part, I'm glad of it."
"It was a conspiracy," growled the captain. "That rascal, Maurie – "
"Oh, was Maurie in it?"
"Of course. He was the decoy; perhaps he arranged the whole thing."
"Didn't the general want you, then?"
Carg was so enraged that he fairly snorted.
"Want me? Of course he didn't want me! That treacherous little Belgian led me into the waiting room and said the general would see me in a minute. Then he walked away and I sat there like a bump on a log and waited. Finally I began to wonder how Maurie, who was always shy of facing the authorities, had happened to be the general's messenger. It looked queer. Officers and civilians were passing back and forth but no one paid any attention to me; so after an hour or so I asked an officer who entered from an inner room, when I could see the general. He said the general was not there evenings but would be in his office to-morrow morning. Then I showed him my order and he glanced at it and said it was forged; wasn't the general's signature and wasn't in proper form, anyhow. When I started to go he wouldn't let me; said the affair was suspicious and needed investigation. So he took me to a room full of officers and they asked me a thousand fool questions. Said they had no record of a Belgian named Maurie and had never heard of him before. I couldn't figure the thing out, and they couldn't; so finally they let me come back to the ship."
"Strange," mused Uncle John; "very strange!"
"I was so stupid," continued Carg, "that I never thought of Elbl being at the bottom of the affair until I got back and found our launch missing. Then I remembered that Elbl was to have been turned over to the prison authorities to-morrow and like a flash I saw through the whole thing."
"I'm blamed if I do," declared Mr. Merrick.
The others likewise shook their heads.
"He got me out of the way, stole the launch, and is half way to Ostend by this time."
"Alone? And wounded – still an invalid?"
"Doubtless Maurie is with him. The rascal can run an automobile; so I suppose he can run a launch."
"What puzzles me," remarked Patsy, "is how Lieutenant Elbl ever got hold of Maurie, and induced him to assist him, without our knowing anything about it."
"I used to notice them talking together a good bit," said Jones.
"But Clarette has kept Maurie a prisoner. She wouldn't let him come back to the ship."
"He was certainly at liberty to-night," answered Beth. "Isn't this escape liable to be rather embarrassing to us, Uncle John?"
"I'm afraid so," was the reply. "We agreed to keep him safely until the authorities demanded we give him up; and now, at the last minute, we've allowed him to get away."
Anxiety was written on every countenance as they considered the serious nature of this affair. Only Gys seemed composed and unworried.
"Is it too late to go in chase of the launch?" asked Ajo, breaking a long pause. "They're headed for Ostend, without a doubt, and there's a chance that they may run into a sand-bank in the dark, or break down, or meet with some other accident to delay them."
"I believe it's worth our while, sir," answered Carg. "The launch we have is the faster, and the trip will show our good faith, if nothing more."
"Then make ready to start at once," said Ajo, "and I'll dress and go along."
Carg hurried away to give orders and the boy ran to his stateroom. Five minutes later they were away, with four sailors to assist in the capture of the fugitives in case they were overtaken.
It was a fruitless journey, however. At daybreak, as they neared Ostend, they met their stolen launch coming back, in charge of a sleepy Belgian who had been hired to return it. The man frankly stated that he had undertaken the task in order to get to Dunkirk, where he had friends, and he had been liberally paid by a German on crutches, who had one foot missing, and a little Belgian whom he had never seen before, but who, from the description given, could be none other than Maurie.
They carried the man back with them to the Arabella, where further questioning added nothing to their information. They now had proof, however, that Elbl was safe with his countrymen at Ostend and that Maurie had been his accomplice.
"I would not believe," said Patsy, when she heard the story, "that a Belgian could be so disloyal to his country."
"Every nation has its quota of black sheep," replied Uncle John, "and from what we have learned of Maurie's character he is not at all particular which side he serves."
CHAPTER XX
THE DUNES
The escape of a prisoner of war from the American hospital ship was made the subject of a rigid inquiry by the officials and proved extremely humiliating to all on board the Arabella. The commandant showed his irritation by severely reprimanding Mr. Merrick for carelessness, while Captain Carg had to endure a personal examination before a board of inquiry. He was able to prove that he had been at headquarters during the evening of the escape, but that did not wholly satisfy his inquisitors. Finally an order was issued forbidding the Americans to take any more wounded Germans or Austrians aboard their ship, and that seemed to end the unpleasant affair.
However, a certain friction was engendered that was later evidenced on both sides. The American ambulance was no longer favored on its trips to the front, pointed preference being given the English and French Red Cross Emergency Corps. This resulted in few wounded being taken to the Arabella, as the Americans confined their work largely to assisting the injured on the field of battle. The girls were not to be daunted in their determined efforts to aid the unfortunate and every day one of them visited the trenches to assist the two doctors in rendering first aid to the wounded.
The work was no longer arduous, for often entire days would pass without a single casualty demanding their attention. The cold weather resulted in much sickness among the soldiers, however, and Gys found during this period of military inactivity that his medicine chest was more in demand than his case of surgical instruments.
A slight diversion was created by Clarette, who came to the ship to demand her husband from the Americans. It seemed almost impossible to convince her that Maurie was not hidden somewhere aboard, but at last they made the woman understand he had escaped with the German to Ostend. They learned from her that Maurie – or Henri, as she insisted he was named – had several times escaped from her house at night, while she was asleep, and returned at daybreak in the morning, and this information led them to suspect he had managed to have several secret conferences with Lieutenant Elbl previous to their flight. Clarette announced her determination to follow her husband to Ostend, and perhaps she did so, as they did not see her again.
