The word of command was passed forward and immediately a boat was lowered.

“A man and a woman clinging to a table, sir,” an officer reported to Conyers. “We’re bringing them on board.”

Conyers moved to the side of the bridge. He saw Geraldine lifted into the boat, and Thomson, as soon as she was safe, clamber in after her. He watched them hauled up on to the deck of the destroyer and suddenly he recognised them.

“My God!” he exclaimed, as he dashed down the ladder. “It’s Geraldine!”

She was standing on the deck, the wet streaming from her, supported by a sailor on either side. She gasped a little when she saw him. She was quite conscious and her voice was steady.

“We are both here, Ralph,” she cried, “Hugh and I. He saved my life. Thank heavens you are here!”

Already the steward was hastening forward with brandy. Geraldine sipped a little and passed the glass to Thomson. Then she turned swiftly to her brother. There was an unfamiliar look in her face.

“Ralph,” she muttered, “don’t bother about us. Don’t stop for anything else. Can’t you find that submarine? I saw them all—the men—laughing as they passed away!”

Conyers’ eyes blazed for a moment with reminiscent fury. Then his lips parted and he broke into strange, discordant merriment.

“They’ll laugh no more in this world, Geraldine,” he cried, in fierce triumph. “They’re down at the bottom of the sea, every man and dog of them!”
