nothing would be gained by argument. Tony slowly brought the boat around.
"Good-bye," shouted Joe cheerfully.
The stranger did not reply. He stood there, gazing fixedly after them, his arms still folded, still tapping the revolver against his shoulder as the motorboat made its way out of the strange bay, out into open water.
"Looks as if he didn't want us around," remarked Tony, as soon as the Napoli was out of the cove.
"I'll say he didn't!" exclaimed Frank. "What a wicked looking customer he was! I expected to see him start popping at us with that gun of his before we got out."
"I don't want to run into him again," Joe declared. "He sure gave us our orders. And he meant 'em, too."
"I wonder who he is," said Tony.
"Do you think—Fellows! do you think it could have been Snackley?" shouted Frank.
