He was about to put wood on these, when he heard a rustling.
“What was that?” he asked himself, turning quickly.
Then he saw the form of a man stealing away from the vicinity of the camp.
“That’s the guide,” he whispered, his suspicions instantly aroused. “Now, I wonder what he’s up to?”
He saw the form melting into the darkness, and wondered if he should call Merriwell or some member of the party.
“No, I’ll look into this thing myself!” he decided.
He had no weapon save a pocket knife; but, nevertheless, he set out after the gliding form he supposed to be the guide.
“I must be careful, or I’ll miss him!” he thought, stopping when clear of the camp. “He walks like a shadow.”
He heard the bushes rustle, and, guided by the sound, hurried on, and soon came again in sight of the stealthy figure. He was still sure it was the guide, and was much exercised as to why the man should be astir at that hour of the night.
Straight across the island went the man, with Diamond hanging closely behind.
