"Ask ahead," returned Joe. "If you want to know whether I was scared, I'll say I was, but I was too busy getting pictures to notice it. If it is something else——"
"It is," interrupted Blake, and his manner was grave. "Come below and I'll tell you. I don't want any one else to hear."
Wondering somewhat at their friend's manner, Joe and Charlie went to their stateroom, and there Blake closed the door and took the dark cloth down from the mirror. A look into it showed that the transom of the room opposite—the cabin of Levi Labenstein—had been closed.
"So we can't tell whether he's in there or not," said Blake.
"Did you want to talk about him?" asked Joe.
"Yes, him and the lieutenant. Did you fellows happen to notice what they were doing when the submarine was attacking us?"
"Not especially," answered Joe. "I did see Lieutenant Secor looking at us as we worked the camera, but I didn't pay much attention to him."
"It wasn't him so much as it was the German," went on Blake.
"In what way?"
"Did you see where he was standing when the submarine came out of the water?"
