"Doctor, you were quite right," said I. "There is something wrong about that place."

"I thought you would change your mind," he answered, rather triumphantly. "You have had a bad night, eh? Shall I make you a pick-me-up? I have a capital recipe."

"No, thanks," I cried. "But I would like to tell you what happened."

I then tried to explain as clearly as possible precisely what had occurred, not omitting to state that I had been scared as I had never been scared in my whole life before. I dwelt particularly on the phenomenon of the porthole, which was a fact to which I could testify, even if the rest had been an illusion. I had closed it twice in the night, and the second time I had actually bent the bra.s.s in wrenching it with my stick. I believe I insisted a good deal on this point.

"You seem to think I am likely to doubt the story," said the doctor, smiling at the detailed account of the state of the porthole. "I do not doubt it in the least. I renew my invitation to you. Bring your traps here, and take half my cabin."

"Come and take half of mine for one night," I said. "Help me to get at the bottom of this thing."

"You will get to the bottom of something else if you try," answered the doctor.

"What?" I asked.

"The bottom of the sea. I am going to leave the ship. It is not canny."

"Then you will not help me to find out----"

"Not I," said the doctor, quickly. "It is my business to keep my wits about me--not to go fiddling about with ghosts and things."

"Do you really believe it is a ghost?" I inquired, rather contemptuously. But as I spoke I remembered very well the horrible sensation of the supernatural which had got possession of me during the night. The doctor turned sharply on me----

"Have you any reasonable explanation of these things to offer?" he asked. "No; you have not. Well, you say you will find an explanation. I say that you won't, sir, simply because there is not any."

"But, my dear sir," I retorted, "do you, a man of science, mean to tell me that such things cannot be explained?"

"I do," he answered, stoutly. "And, if they could, I would not be concerned in the explanation."

I did not care to spend another night alone in the state-room, and yet I was obstinately determined to get at the root of the disturbances. I do not believe there are many men who would have slept there alone, after pa.s.sing two such nights. But I made up my mind to try it, if I could not get any one to share a watch with me. The doctor was evidently not inclined for such an experiment. He said he was a surgeon, and that in case any accident occurred on board he must always be in readiness. He could not afford to have his nerves unsettled. Perhaps he was quite right, but I am inclined to think that his precaution was prompted by his inclination. On inquiry, he informed me that there was no one on board who would be likely to join me in my investigations, and after a little more conversation I left him. A little later I met the captain, and told him my story. I said that if no one would spend the night with me I would ask leave to have the light burning all night, and would try it alone.

"Look here," said he, "I will tell you what I will do. I will share your watch myself, and we will see what happens. It is my belief that we can find out between us. There may be some fellow skulking on board, who steals a pa.s.sage by frightening the pa.s.sengers. It is just possible that there may be something queer in the carpentering of that berth."

I suggested taking the ship's carpenter below and examining the place; but I was overjoyed at the captain's offer to spend the night with me.

He accordingly sent for the workman and ordered him to do anything I required. We went below at once. I had all the bedding cleared out of the upper berth, and we examined the place thoroughly to see if there was a board loose anywhere, or a panel which could be opened or pushed aside. We tried the planks everywhere, tapped the flooring, unscrewed the fittings of the lower berth and took it to pieces--in short, there was not a square inch of the state-room which was not searched and tested. Everything was in perfect order, and we put everything back in its place. As we were finishing our work, Robert came to the door and looked in.

"Well, sir--find anything, sir?" he asked with a ghastly grin.

"You were right about the porthole, Robert," I said, and I gave him the promised sovereign. The carpenter did his work silently and skilfully, following my directions. When he had done he spoke.

"I'm a plain man, sir," he said. "But it's my belief you had better just turn out your things and let me run half a dozen four inch screws through the door of this cabin. There's no good never came o' this cabin yet, sir, and that's all about it. There's been four lives lost out o'

here to my own remembrance, and that in four trips. Better give it up, sir--better give it up!"

"I will try it for one night more," I said.

"Better give it up, sir--better give it up! It's a precious bad job,"

repeated the workman, putting his tools in his bag and leaving the cabin.

But my spirits had risen considerably at the prospect of having the captain's company, and I made up my mind not to be prevented from going to the end of the strange business. I abstained from Welsh rare-bits and grog that evening, and did not even join in the customary game of whist.

I wanted to be quite sure of my nerves, and my vanity made me anxious to make a good figure in the captain's eyes.

IV.

The captain was one of those splendidly tough and cheerful specimens of seafaring humanity whose combined courage, hardihood, and calmness in difficulty leads them naturally into high positions of trust. He was not the man to be led away by an idle tale, and the mere fact that he was willing to join me in the investigation was proof that he thought there was something seriously wrong, which could not be accounted for on ordinary theories, nor laughed down as a common superst.i.tion. To some extent, too, his reputation was at stake, as well as the reputation of the ship. It is no light thing to lose pa.s.sengers overboard, and he knew it.

About ten o'clock that evening, as I was smoking a last cigar, he came up to me and drew me aside from the beat of the other pa.s.sengers who were patrolling the deck in the warm darkness.

"This is a serious matter, Mr. Brisbane," he said. "We must make up our minds either way--to be disappointed or to have a pretty rough time of it. You see, I cannot afford to laugh at the affair, and I will ask you to sign your name to a statement of whatever occurs. If nothing happens to-night we will try it again to-morrow and next day. Are you ready?"

So we went below, and entered the state-room. As we went in I could see Robert the steward, who stood a little further down the pa.s.sage, watching us, with his usual grin, as though certain that something dreadful was about to happen. The captain closed the door behind us and bolted it.

"Supposing we put your portmanteau before the door," he suggested. "One of us can sit on it. Nothing can get out then. Is the port screwed down?"

I found it as I had left it in the morning. Indeed, without using a lever, as I had done, no one could have opened it. I drew back the curtains of the upper berth so that I could see well into it. By the captain's advice I lighted my reading-lantern, and placed it so that it shone upon the white sheets above. He insisted upon sitting on the portmanteau, declaring that he wished to be able to swear that he had sat before the door.

Then he requested me to search the state-room thoroughly, an operation very soon accomplished, as it consisted merely in looking beneath the lower berth and under the couch below the porthole. The s.p.a.ces were quite empty.

"It is impossible for any human being to get in," I said, "or for any human being to open the port."

"Very good," said the captain, calmly. "If we see anything now, it must be either imagination or something supernatural."

I sat down on the edge of the lower berth.

"The first time it happened," said the captain, crossing his legs and leaning back against the door, "was in March. The pa.s.senger who slept here, in the upper berth, turned out to have been a lunatic--at all events, he was known to have been a little touched, and he had taken his pa.s.sage without the knowledge of his friends. He rushed out in the middle of the night, and threw himself overboard, before the officer who had the watch could stop him. We stopped and lowered a boat; it was a quiet night, just before that heavy weather came on; but we could not find him. Of course his suicide was afterwards accounted for on the ground of his insanity."

"I suppose that often happens?" I remarked, rather absently.

"Not often--no," said the captain; "never before in my experience, though I have heard of it happening on board of other ships. Well, as I was saying, that occurred in March. On the very next trip--What are you looking at?" he asked, stopping suddenly in his narration.

I believe I gave no answer. My eyes were riveted upon the porthole. It seemed to me that the bra.s.s loop-nut was beginning to turn very slowly upon the screw--so slowly, however, that I was not sure it moved at all.

I watched it intently, fixing its position in my mind, and trying to ascertain whether it changed. Seeing where I was looking, the captain looked too.

"It moves!" he exclaimed, in a tone of conviction. "No, it does not," he added, after a minute.

"If it were the jarring of the screw," said I, "it would have opened during the day; but I found it this evening jammed tight as I left it this morning."

I rose and tried the nut. It was certainly loosened, for by an effort I could move it with my hands.

"The queer thing," said the captain, "is that the second man who was lost is supposed to have got through that very port. We had a terrible time over it. It was in the middle of the night, and the weather was very heavy; there was an alarm that one of the ports was open and the sea running in. I came below and found everything flooded, the water pouring in every time she rolled, and the whole port swinging from the top bolts--not the porthole in the middle. Well, we managed to shut it, but the water did some damage. Ever since that the place smells of sea-water from time to time. We supposed the pa.s.senger had thrown himself out, though the Lord only knows how he did it. The steward kept telling me that he could not keep anything shut here. Upon my word--I can smell it now, cannot you?" he inquired, sniffing the air suspiciously.

"Yes--distinctly," I said, and I shuddered as that same odour of stagnant sea-water grew stronger in the cabin. "Now, to smell like this, the place must be damp," I continued, "and yet when I examined it with the carpenter this morning everything was perfectly dry. It is most extraordinary--hallo!"

My reading-lantern, which had been placed in the upper berth, was suddenly extinguished. There was still a good deal of light from the pane of ground gla.s.s near the door, behind which loomed the regulation lamp. The ship rolled heavily, and the curtain of the upper berth swung far out into the state-room and back again. I rose quickly from my seat on the edge of the bed, and the captain at the same moment started to his feet with a loud cry of surprise. I had turned with the intention of taking down the lantern to examine it, when I heard his exclamation, and immediately afterwards his call for help. I sprang towards him. He was wrestling with all his might, with the bra.s.s loop of the port. It seemed to turn against his hands in spite of all his efforts. I caught up my cane, a heavy oak stick I always used to carry, and thrust it through the ring and bore on it with all my strength. But the strong wood snapped suddenly, and I fell upon the couch. When I rose again the port was wide open, and the captain was standing with his back against the door, pale to the lips.

"There is something in that berth!" he cried, in a strange voice, his eyes almost starting from his head. "Hold the door, while I look--it shall not escape us, whatever it is!"
