Catin waited breathless in his hiding place until they returned. "By heaven, they didn't find it!" he breathed eagerly.

Pauline and Ensign Summers stood at the rail watching the foamy rush of a fast motor boat, when a hail sounded across the water.

A man was standing up in the motor boat and calling through a megaphone.

Summers raised his glasses. "Do you know who that is?" he asked laughingly.

"Of course not. What does he want?"

"It's Harry, and I suspect he wants to take you away from us."

Pauline uttered an exclamation of annoyance.

"Isn't he silly!" she cried, "One would think I was, a baby, the way he watches me."

Soon the voice of Harry could be plainly distinguished.
