Mick asked.Nancy glanced ahead to make sure that Theo couldn’t hear them. Then she showed Mick the marking on the cushion. “I saw the same cushions in that cave.”“Are you sure?” Mick questioned. “We don’t know the Greek alphabet. Maybe some of the letters just look the same.”“I’m positive,” she said emphatically. “It was a star, followed, by these symbols.” A quick search of the other cushions on the aft deck revealed that they were all marked the same way.Mick’s eyes darkened, and he said, “Now that I think of it, what was Theo doing on that deserted part of Dragonisi—after he refused to take us there? He could have been on his way to see the people in the cave!”Nancy tensed. “And remember that woman we saw him talking to, next to the snorkelers? She had red hair . . .”“Just like the woman in the cave,” Mick finished. “I think it’s time Theo gave us some solid answers,” he added, suddenly on his feet.Nancy grabbed his arm and pulled him back.
