"It would seem so," Ned replied, "but, of course, the initial may be merely a coincidence."
"I guess we're in for it."
"But how did the Diver get here so soon after our arrival?" asked one of the boys.
Ned looked grave for a moment, and then replied, his manner showing how fully he appreciated the importance of his words:
"What I fear is that she got here first."
"And found the wreck?"
"She might have done so."
"Did you see anything of the Cutaria down there?" asked Frank.
"Not a bloomin' thing," answered Jimmie, making his appearance on the conning tower.
