"Let be!" croaked Huldricksson; his voice was thick and lifeless as though forced from a dead throat; his lips were cracked and dry and his parched tongue was black. "Let be! Go! Let be!"

The Portuguese had picked himself up, whimpering with rage and knife in hand, but as Huldricksson's voice reached him he stopped.

Amazement crept into his eyes and as he thrust the blade back into his belt they softened with pity.

"Something veree wrong wit' Olaf," he murmured to me. "I think he crazee!" And then Olaf Huldricksson began to curse us. He did not speak--he howled from that hideously dry mouth his imprecations. And all the time his red eyes roamed the seas and his hands, clenched and rigid on the wheel, dropped blood.

"I go below," said Da Costa nervously. "His wife, his daughter--" he darted down the companionway and was gone.

Huldricksson, silent once more, had slumped down over the wheel.

Da Costa's head appeared at the top of the companion steps.

"There is n.o.body, n.o.body," he paused--then--"n.o.body--nowhere!" His hands flew out in a gesture of hopeless incomprehension. "I do not understan'."

Then Olaf Huldricksson opened his dry lips and as he spoke a chill ran through me, checking my heart.

"The sparkling devil took them!" croaked Olaf Huldricksson, "the sparkling devil took them! Took my Helma and my little Freda! The sparkling devil came down from the moon and took them!"

He swayed; tears dripped down his cheeks. Da Costa moved toward him again and again Huldricksson watched him, alertly, wickedly, from his bloodshot eyes.

I took a hypodermic from my case and filled it with morphine. I drew Da Costa to me.

"Get to the side of him," I whispered, "talk to him." He moved over toward the wheel.

"Where is your Helma and Freda, Olaf?" he said.

Huldricksson turned his head toward him. "The shining devil took them," he croaked. "The moon devil that spark--"

A yell broke from him. I had thrust the needle into his arm just above one swollen wrist and had quickly shot the drug through. He struggled to release himself and then began to rock drunkenly. The morphine, taking him in his weakness, worked quickly. Soon over his face a peace dropped. The pupils of the staring eyes contracted. Once, twice, he swayed and then, his bleeding, prisoned hands held high and still gripping the wheel, he crumpled to the deck.

With utmost difficulty we loosed the thongs, but at last it was done.

We rigged a little swing and the Tonga boys slung the great inert body over the side into the dory. Soon we had Huldricksson in my bunk. Da Costa sent half his crew over to the sloop in charge of the Cantonese.

They took in all sail, stripping Huldricksson's boat to the masts and then with the Brunhilda nosing quietly along after us at the end of a long hawser, one of the Tonga boys at her wheel, we resumed the way so enigmatically interrupted.

I cleansed and bandaged the Norseman's lacerated wrists and sponged the blackened, parched mouth with warm water and a mild antiseptic.

Suddenly I was aware of Da Costa's presence and turned. His unease was manifest and held, it seemed to me, a queer, furtive anxiety.

"What you think of Olaf, sair?" he asked. I shrugged my shoulders.

"You think he killed his woman and his babee?" He went on. "You think he crazee and killed all?"

"Nonsense, Da Costa," I answered. "You saw the boat was gone. Most probably his crew mutinied and to torture him tied him up the way you saw. They did the same thing with Hilton of the Coral Lady; you'll remember."

"No," he said. "No. The crew did not. n.o.body there on board when Olaf was tied."

"What!" I cried, startled. "What do you mean?"

"I mean," he said slowly, "that Olaf tie himself!"

"Wait!" he went on at my incredulous gesture of dissent. "Wait, I show you." He had been standing with hands behind his back and now I saw that he held in them the cut thongs that had bound Huldricksson. They were blood-stained and each ended in a broad leather tip skilfully spliced into the cord. "Look," he said, pointing to these leather ends. I looked and saw in them deep indentations of teeth. I s.n.a.t.c.hed one of the thongs and opened the mouth of the unconscious man on the bunk. Carefully I placed the leather within it and gently forced the jaws shut on it. It was true. Those marks were where Olaf Huldricksson's jaws had gripped.

"Wait!" Da Costa repeated, "I show you." He took other cords and rested his hands on the supports of a chair back. Rapidly he twisted one of the thongs around his left hand, drew a loose knot, shifted the cord up toward his elbow. This left wrist and hand still free and with them he twisted the other cord around the right wrist; drew a similar knot. His hands were now in the exact position that Huldricksson's had been on the Brunhilda but with cords and knots hanging loose. Then Da Costa reached down his head, took a leather end in his teeth and with a jerk drew the thong that noosed his left hand tight; similarly he drew tight the second.

He strained at his fetters. There before my eyes he had pinioned himself so that without aid he could not release himself. And he was exactly as Huldricksson had been!

"You will have to cut me loose, sair," he said. "I cannot move them.

It is an old trick on these seas. Sometimes it is necessary that a man stand at the wheel many hours without help, and he does this so that if he sleep the wheel wake him, yes, sair."

I looked from him to the man on the bed.

"But why, sair," said Da Costa slowly, "did Olaf have to tie his hands?"

I looked at him, uneasily.

"I don't know," I answered. "Do you?"

He fidgeted, avoided my eyes, and then rapidly, almost surrept.i.tiously crossed himself.

"No," he replied. "I know nothing. Some things I have heard--but they tell many tales on these seas."

He started for the door. Before he reached it he turned. "But this I do know," he half whispered, "I am d.a.m.ned glad there is no full moon tonight." And pa.s.sed out, leaving me staring after him in amazement.

What did the Portuguese know?

I bent over the sleeper. On his face was no trace of that unholy mingling of opposites the Dweller stamped upon its victims.

And yet--what was it the Norseman had said?

"The sparkling devil took them!" Nay, he had been even more explicit--"The sparkling devil that came down from the moon!"

Could it be that the Dweller had swept upon the Brunhilda, drawing down the moon path Olaf Huldricksson's wife and babe even as it had drawn Throckmartin?

As I sat thinking the cabin grew suddenly dark and from above came a shouting and patter of feet. Down upon us swept one of the abrupt, violent squalls that are met with in those lat.i.tudes. I lashed Huldricksson fast in the berth and ran up on deck.

The long, peaceful swells had changed into angry, choppy waves from the tops of which the spindrift streamed in long stinging lashes.

A half-hour pa.s.sed; the squall died as quickly as it had arisen. The sea quieted. Over in the west, from beneath the tattered, flying edge of the storm, dropped the red globe of the setting sun; dropped slowly until it touched the sea rim.

I watched it--and rubbed my eyes and stared again. For over its flaming portal something huge and black moved, like a gigantic beckoning finger!

Da Costa had seen it, too, and he turned the Suwarna straight toward the descending orb and its strange shadow. As we approached we saw it was a little ma.s.s of wreckage and that the beckoning finger was a wing of canvas, sticking up and swaying with the motion of the waves. On the highest point of the wreckage sat a tall figure calmly smoking a cigarette.

We brought the Suwarna to, dropped a boat, and with myself as c.o.xswain pulled toward a wrecked hydroairplane. Its occupant took a long puff at his cigarette, waved a cheerful hand, shouted a greeting. And just as he did so a great wave raised itself up behind him, took the wreckage, tossed it high in a swelter of foam, and pa.s.sed on. When we had steadied our boat, where wreck and man had been was--nothing.

There came a tug at the side--, two muscular brown hands gripped it close to my left, and a sleek, black, wet head showed its top between them. Two bright, blue eyes that held deep within them a laughing deviltry looked into mine, and a long, lithe body drew itself gently over the thwart and seated its dripping self at my feet.

"Much obliged," said this man from the sea. "I knew somebody was sure to come along when the O'Keefe banshee didn't show up."

"The what?" I asked in amazement.
