Joe noticed that the stranger cast frequent anxious glances toward the shore. Suddenly an expression of alarm crossed the man's face, and Joe saw that he was watching two figures who had appeared on the road and who were running along, waving their arms, evidently trying to attract attention.
"Somebody signaling to us," he said to Frank.
Frank looked up. The two men on the road were making frantic efforts to draw attention, as they waved their arms and leaped about like lunatics.
"Friends of yours?" asked Frank of their passenger.
The florid-faced man laughed. The laugh was meant to be carefree and hearty, but there was no disguising the note of uneasiness beneath it.
