"I don't know. But I think the best thing to do is to go down to where that motor boat was tied up. I don't think they can leave unless they use that boat—unless, of course, they have some craft we haven't as yet seen."
There was a well-defined path running from the cave down to the shore of the island. This they followed, through the patch of woods and over some rocks. Then they came to an opening where were located several delapidated buildings. Not far from one building were the remains of a re cent camp.
"I believe this was the camp Darkingham and those with him made!" ejaculated Dick. "They have gone—maybe they have left the island!"
"Come on, I don't'like this!" put in Tom, and broke into a run for the old dock, and the others followed on his heels.
They were still a hundred yards from the dock when Tom let up a shout:
"There they are!"
"Where?" asked Dick.
"In the motor boat!"
"Who?" questioned Sam.
"The Sobber crowd—and they have Mrs. Stanhope with them."
"Stop! stop!" yelled Dick, at the top of his voice. "Stop, I tell you! Mrs. Stanhope!"
