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.
