Dirk and Summer sat silently as Perlmutter read of the resulting tragedy. With no propulsion, the sub remained submerged for twelve hours, fearing that additional aircraft had been called to the scene. Surfacing at midday, they found themselves in an empty sea, drifting to the southeast. Carried past the shipping lanes and without a long-range radio, the officers feared they might drift to their deaths in the Antarctica. Captain De Julio ordered the crew to abandon ship, and they took to the four life rafts stowed beneath the forward deck, saluting their beloved vessel as they left her side. In a mix-up of orders, the last officer off failed to prime the scuttle charges and sealed the main hatch. Rather than sinking before them, the Barbarigo drifted off toward the horizon.

Perlmutter stopped reading and raised his eyebrows like a pair of drawbridges. “My word,” he said quietly. “That is most curious.”

“What happened to the other three boats?” Summer asked.

“The log entries become spottier at this point,” Perlmutter said. “They attempted to reach South Africa and were within sight of land when a storm struck. The boats were dispersed in the rough seas, and Captain De Julio said the men in his boat never again saw the other three. During the ordeal they lost five men, all their food and water, and their sail and oars. The raft was carried east, drifting away from shore with the coastal current. Eventually the weather turned hot and dry. With no fresh water, they lost two more crewmen, leaving only the captain, the first officer, and two engineers.”

“Ravaged by thirst, they eventually spotted land again and were able to paddle closer. High winds and huge swells carried them ashore and tossed them onto the beach,” Perlmutter said. “They found themselves in a hot desert, desperate for water. The last entry states the captain went off alone in search of water, as the others were too weak to walk. The journal ends, ‘God bless the Barbarigo and her crew.’”

“We can attest to the barrenness of the region,” Summer said after a time. “What a tragedy that they nearly made it safely to South Africa and ended up a thousand miles away in Madagascar.”

“They fared slightly better than the crewmen in the other three boats,” Dirk said.

Perlmutter nodded, though he appeared lost in thought. He rose from his seat and padded into the living room, then returned a few minutes later with an armful of books and an inquisitive look. “Congratulations, Summer. It would appear as if you have solved two enduring mysteries of the sea.”

“Two?” she asked.

“Yes, the fate of the Barbarigo and the identity of the South Atlantic Wraith.”

“I’ll buy the former,” Dirk said, “but what’s this Wraith?”
