Their return to the Bennington again through a pathway of light that Thorpe knew was safe under the black muzzles of the destroyer's guns.
Or was it, he asked himself. Safe! Was anything safe from this devilish mystery that could pluck each cowering human from the lowest depths of this steel freighter, that could drag her down in the water till the radio man sent his cry: "We are sinking!.."
He told Brent quietly, after the ensign had reported, of the struggles in the wireless room and its few remaining traces. And he watched with the commander through the hour of darkness while the Bennington steamed in slow circles about the abandoned hulk, while her search-lights played endlessly over the empty waters and the men at the guns cast wondering glances at their skipper who ordered such strange procedure when no danger was there.
With daylight the scene lost its sense of mysterious threat, and Thorpe was eager to return to the abandoned ship.
"I might find something," he said, "some trace or indication of what we have to fight."
"I must leave," said Commander Brent. "Oh, I'm coming back, never fear," he added, at the look of dismay on Thorpe's face. The thought of leaving this mystery unsolved was more than that young seeker after adventure could accept.
"I'm coming back," Brent repeated. "I've been in communication with the Admiral – Honolulu has relayed the messages through. All code, of course; we mustn't alarm the whole Pacific with our nightmares. The old man says to stick around and get the low-down on this damn thing."
"Then why leave?" objected Thorpe.
Because I am coming around to your way of thinking, Thorpe. Because I am as certain as can be that we have a monster of some sort to deal with … and because I haven't any depth charges. I want to run up to the supply station at Honolulu and get a couple of ash-cans of TNT to lay on top of the brute if we sight him."
"Glory be!" said Thorpe fervently. "That sounds like business. Go and get your eggs and perhaps we can feed them to this devil – raw… And I think I'll stay here, if you will be back by dark."
"Better not," the other objected; but Thorpe overruled him.
"This thing attacks in the dark," he said. "I will lay a little bet on that. It left the orang-outang on the Minnie R.– quit at the first sign of daylight. I will be safe through the day, and besides, the beast has gutted this ship. It won't return, I imagine. And if I stay there for the day – live as they lived, the men who manned that ship – I may have some information that will be of help when you get back. But for Heaven's sake, Brent, don't stop to pick any flowers on the way."
"It's your funeral," said Brent not too cheerfully. "The old man said to give you every assistance, and perhaps that includes helping you commit suicide."
But Robert Thorpe only laughed as Commander Brent gave his orders for a small boat to be lowered. A ship's lantern and rockets for night signals were taken at the officer's orders. "We'll be back before dark," he said, "but take these as a precaution."
One favor Thorpe asked – that the ship's carpenter go over with him and help him to make a strong-barred retreat of the wireless cabin.
"And I'll talk to you occasionally," he told Brent. "I tried the key while I was aboard; the wireless is working on its batteries."
He waved a cheery good-by as the small boat pulled away. "And hurry back," he called. The destroyer commander nodded an emphatic assent.
On board the Nagasaki Maru, Thorpe directed the carpenter and his helpers in the work he wanted done. The man seemed to know instinctively where to put his hands on needed supplies, and the result was a virtual cage of strong oak bars enclosing the wireless room, and braces of oak to bar the single door. Thorpe was not assuming any bravado in his feeling of safety, but he was doing what he had done in many other tight corners, and he prepared his defences in advance.
These included weapons of offense as well. As the boat with the destroyer's men pulled back to the Bennington, he placed in easy reach in a corner of the room a heavy calibered rifle he had taken from his belongings.
And, still, with all his feeling of security, there was a strange depression fell upon him when the Bennington's narrow hull was small upon the horizon, and then that, too, was gone and only the heaving swells and the wallowing hulk were his companions.
Only these? He shivered slightly as he thought of that unseen watcher with the devil-eyes whose presence Captain Wilkins had felt – and his men, and the poor terrified ape! He deliberately put from his mind the thought of this; no use to start the day with morbid fears. He went below to examine the cabins. But he carried the heavy elephant gun with him wherever he went.
Below decks the signs of the marauder were everywhere, yet there was little to be learned. The slimy trails dried quickly and vanished, but not before Thorpe had traced them to the uttermost depths of the ship.
There was not a nook or corner that had gone unsearched in the horrible quest for human food. And one thing impressed itself forcibly upon the man's mind. He found a lantern, and he used it of necessity in his explorations, but this thing had gone through the dark and with unerring certainty had found its way to every victim.
"Can it see in the dark?" Thorpe questioned. "Or…" He visioned dimly some denizen of the vast depths, living beyond the limits of the sun's penetration, far in the abysmal darkness where its only light must be self-made. But his mind failed in the attempt to picture what manner of horror this thing might be.
Even in the hold its evil traces were found. There were tiers of metal drums that still shone wet in his lantern's light. Calcium carbide – for making acetylene, he supposed – marked "Made in U.S.A." The Nagasaki must have been westward bound.
He went, after an hour or so, to the wireless room, and only when he relaxed in the safety of his improvised fortress did he realize how tense had been every nerve and muscle through his long search. He tried the wireless and got an instant response from the destroyer.
"Don't shoot it too fast," he spelled out slowly to the distant operator: "I am only a dub. Just wanted to say hello and report all O.K."
"Fine," was the steady, careful response. "We have had a little trouble with our condensers – " There was a short pause, then the message continued, this portion dictated by the commander. "Delay not important. We will be back as agreed. Have picked up S. S. Adelaide bound east in your latitude. Warned her to take northerly course account derelict. See you later. Signed, Brent, commanding U. S. S. Bennington."
The man in the barred room tapped off his acknowledgement and closed the key. He suddenly realized he had had no breakfast, and the hours had been slipping past. He took his gun again and went down to the galley to prepare some coffee. It was not the time or place for an enjoyable meal, but he would have relished it more had he not pictured the Adelaide and her lovely owner steaming across these threatening seas.
He knew the captain of the Adelaide. "Obstinate pigheaded old Scotchman!" "Hope he takes Brent's advice. Of course Brent couldn't tell him the truth. We can't blat this wild yarn all over the air or the passenger lines would have our scalps. But I wish the Adelaide was safe in Manila."
His explorations in the afternoon were half-hearted and perfunctory. There was nothing more to be learned. But he had seen in his mind some vague outline of what they must meet. He saw a something, mammoth, huge, that could grasp and hold an ocean freighter – against whose great body he had seen the waves dash in a line of white spray. Yet a something that could force its way down narrow passages, could press with terrific strength on bolted doors and crush them inward, wrecked and splintered. Some serpentine thing that felt and saw its way and crawled so surely through the dark – found its prey – seized it – and carried off a man as easily as it might a mouse.
No octopus, no matter what proportions, filled the description. He gave up trying to see too clearly the awful thing. And he kept away from the ship's rail when once he had ventured near. For there had come to him a feeling of fear that had sent the waves of cold trickling and prickling up his spine. Was there something really there?.. A waiting lurking horror in the depths?
"The eyes," he thought, "the eyes!.." And he went more quickly than he knew to his barred retreat where again he might breathe quietly.
The position of the deserted ship was south of the regular steamer lanes on the TransPacific run. Only a trace of smoke on the northern horizon marked through the afternoon the passage of other craft. It was a long and lonely vigil for the waiting man. But the Bennington would return, and he listened in at intervals hoping to hear her friendly signal.
The batteries operating the Nagasaki's wireless were none too strong; Thorpe saved their strength, though he tried at times to raise the Bennington somewhere beyond his reach.
The sun was touching the horizon when he got his first response. "Keep up the old nerve," admonished the slow, careful sending of the Bennington's operator. "We have been delayed but we are on our way. Signed, Brent."
The man in the wireless room placed the oak bars across the door, and tried to believe he was nonchalant and unafraid as he laid out extra clips of cartridges. But his eyes persisted in following the sinking sun, and he watched from within his cage the coming of the quick dark.
The protecting glare of day must be unbearable to this monster from the lightless depths, and daylight was vanishing. Thorpe's mind was searching for additional means of defense. He found it in the cargo he had seen. The drums of carbide! He could scatter it on the deck – it reacted with water, and those slimy arms, if they came and touched it, could find the contact hot. He took his lantern and went hastily below to stagger back with a drum upon his shoulder.
In the half-light that was left him he forced the cover and then rolled the drum about the swaying deck. The gray, earthly lumps of carbide formed erratic lines. Useless perhaps, he admitted, but the threatening dark forced the man to use every means at his command.
He was scattering the contents of a second drum when he stiffened abruptly to rigid attention.
The ship, thrown broadside to the wide-spaced swells, had rolled endlessly with a monotonous motion. But now the deck beneath him was steadying. It assumed an abnormal levelness. The boat rose and fell with the waves, but it no longer rolled. There was something beneath holding, drawing on it.
Thorpe knew in that frozen second what it meant. The drum clattered to the rail as he dashed for his room. Gun in hand, he watched with staring eyes where the deserted deck showed dim and vague in the light of the stars and the bow of the ship was lost in the uncertain dark of night.
Wide-eyed he watched into the blackness, and he listened with desperate attention for some slightest sound beyond the splashing of waves and the creaking of spars.
Far in the west a light appeared, to glow and vanish and glow again in the tumbling waters. The Bennington! His heart leaped at the thought, then sank as he knew the destroyer's lights would not appear from that direction.
Through a slow hour that seemed an eternity the oncoming ship drew near, and he knew with a sudden, startling certainty that it was the Adelaide– and Ruth Allaire – coming on, through into the horror awaiting.
He leaned forward tensely as a sound reached his ears. A ghostly echo of a sound, like the softest of smooth, slipping fabric upon hard steel. And as he listened, before his staring eyes, a something came between him and the lighted yacht.
It wavered and swung in the darkness. It was formless, uncertain of outline, and it swung in the night out beyond the ship's rail till it suddenly neared, waved high overhead, and the cold light of the stars shone in pale reflection from an enormous, staring eye.
It surmounted a serpentine form that took shape in the dim radiance without and came lower in undulating folds to crash heavily upon the deck.
horpe's hand was upon the wireless key. He had wanted to warn off the yacht, but not till the thud of the creature on the bare deck proved its reality could he force his cold fingers to press the key.
Then, fast as his inexperience allowed, he called frantically for the Adelaide. He spelled her name, over and over… Would the sleepy operator never answer?
