been quite vain. Her engines had been shut down; there was no steerage-way for the Nagasaki Maru, and, from all they could see, there were no human hands to drag at the levers of her waiting engines nor to twirl with sure touch the deserted helm. The Nagasaki Maru was abandoned.
The lights held steadily upon her as the Bennington came alongside and a boat was swung out smartly in its davits. But Thorpe knew he was not alone in his wild surmise as to the cause of the catastrophe.
"Throw your lights around the water occasionally," Brent ordered. "Let me know if you see anything."
"Yes sir," said the man at the search-light. "I will report if I spot any survivors or boats."
"Report anything you see," said Commander Brent curtly.
"You go aboard if you want to," he suggested to Thorpe. "I will stay here and be ready if you need help."
Thorpe nodded with approval as the small boat pulled away in the dark, for there was activity apparent on the destroyer not warranted by a mere rescue at sea. Gun-crews rushed to their stations; the tarpaulin covers were off of the guns, and their slender lengths gleamed where they covered the course of the boat.
"Brent is ready," Thorpe admitted, "for anything."
They found the iron ladder against the ship's side, and a sailor sprang for it and made his way aboard. Thorpe was not the last to set foot on deck, and he shuddered involuntarily at the eery silence he knew awaited them.
It was the Minnie R. over again, as he expected, but with a difference. The sailing vessel, before he boarded it, had been for some time exposed to the sun, while the Nagasaki Maru had not. And here there were slimy trails still wet on the decks.
He went first to the wireless room. He must know the final answer to that interrupted message, and he found it in emptiness. No radio man was waiting him there, nor even a body to show the loser of an unequal battle. But there was blood on the door-jamb where a body – the man's body, Thorpe was sure – had been smashed against the wood. A wisp of black hair in the blood gave its mute evidence of the hopeless fight. And the slime, like the trails on the deck, smeared with odorous vileness the whole room.
Thorpe went again to the deck, and, as on the other ship, he breathed deeply to rid his lungs and nostrils of the abhorrent stench. The ensign in charge of the boarding party approached.
"What kind of a rotten mess is this?" he demanded. "The ship is filthy and not a soul on board. Not a man of them, officers or crew, and the boats are all here. It's absolutely amazing, isn't it?"
"No," Thorpe told him, "about what we expected. What do you make of this?" He touched with his foot a broad trail that shone wet in the Bennington's lights.
"The Lord knows," said the ensign in wonder. "It's all over and it smells like a rotten dead fish. Well, we will be going back, sir." He called to a petty officer to round up the men, and the boat was brought alongside.
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
