"Don't be a fool," I answered. "There's a submerged rock right across here." Page 191.

"What's the matter?" he shouted. "And where's Arthur?"

"He's climbing down from that rock," I answered, as Duncombe came alongside. "I've just stopped his diving into this pool."

"Why?"

He was by my side now and I pointed downwards to the dark line of cruelly jagged rock. He looked for a moment concerned.

"Jove, I've never noticed those!" he muttered.

"They're barely three feet," I answered. "I can reach them."

Duncombe turned over on his back. We were in the shadow, almost surrounded by rocks. The voices of the others, preparing the lunch, sounded a long way away. I suddenly felt as though I were cut off, as though I could read the thoughts at the back of this man's brain, as though I myself were in danger. All the time he was drawing a little closer to me.

Leonard and Ella Duncombe suddenly appeared upon the summit of one of the lower ranges of rocks.

"Come along to lunch," the former shouted.
