“One night, when I was turning over the matter in my mind, and examining each photograph in the study of my house on the Thames, the solution flashed on me. This tiny speck, which was not a star, and was certainly not Vulcan, was the satellite of another world, and that world was moving on the same orbit as our own earth, following exactly the same course, but being, as it was, immediately opposite to us behind the sun, was never visible! On whatever part of the ellipse we might be, the sun hid our sister world from us, and that was why the voice apparently came from the sun, for it was through the solar centre that the waves must pass. Two earths chasing one another along the same path, never overtaking, never being overtaken, balancing one another perfectly! It was a stupendous thought!
“I conveyed to my unknown friend, who called himself Colson, though I am under the impression that that was due to a misconception on his part as to what Colson meant — he probably thought that ‘Colson’ was the English word for ‘scientist’ — and I asked him to make observations. These he sent to me after a few days, confirming my theory. It was after we had begun to talk a little more freely, and my acquaintance with the language had increased so that I could express myself clearly, that it occurred to me there was an extraordinary similarity both in our lives and our environment. And this is the part in my narrative which you will find difficult to believe — I discovered that these two worlds were not only geographically exact, but that the incidents of life ran along on parallel lines. There were great wars in Neo, great disasters, which were invariably duplicated on our earth, generally from two to three days before or after they had happened in this new world. Nor was it only the convulsions of nature that were so faithfully reproduced. Men and women were doing in that world exactly as we were doing in ours. There were Stock Exchanges and street cars, railways, aeroplanes, as though twin worlds had produced twin identities; twin inspirations.
“I learnt this first when my friend told me that he had been seeking me for some time. He said that he had had a broken knee some five years ago, and during his enforced leisure he had pointed out the possibility of his having another identity. He said he was frequently feeling that the person he met for the first time was one in reality whom he had seen before; and he was conscious that the thing he did to-day, he had done a week before. That is a sensation which I also have had, and which every human being has experienced.
“But to go back to the story of his having been laid up with a broken knee. He had no sooner told me this than I realised that I also had had a broken knee — I had a spill on my motor-bicycle — and that I had spent the hours of my leisure pondering the possibility of there being another inhabited planet! There is a vulgar expression, frequently met with amongst neurotic people, that they have twin souls. In very truth this man was my twin soul: was me, had lived my life, thought my thoughts, performed every action which I performed. The discovery staggered me, and I began to fear for my reason; so I went to London and consulted an eminent Harley Street specialist. He assured me that I was perfectly normal and sane, and offered me the conventional advice that I should go away for a holiday.
“Then one day my astral friend, Colson, incidentally mentioned that there was great excitement in his town because a man had bought some steel stock which had since risen considerably in price — he mentioned the name — and, glancing through a newspaper, I saw the name of a stock which sounded very similar to that of which he had told me. Moreover, the price was very much as he had mentioned it; and the wild idea occurred to me that if happenings were actually duplicated, I might possibly benefit by my knowledge. With great trepidation I invested the whole of my savings, which were not very considerable, in these shares, and a few days later had the gratification of selling out at a colossal profit. I explained to my friend at the next opportunity what I had done, and he was considerably amused, and afterwards took an almost childish delight in advising me as to the violent fluctuations in various stocks. For years I have bought and sold with considerable benefit to myself. Not only that, but I have been able to warn Governments of impending disasters. I informed the Turkish Government of the great Armenian earthquake, and warned the Lamborn Shipping Company of the terrible disaster which overtook one of their largest liners — though I was not thanked for my pains.
“After this had been going on for some years, I was prepared to learn that my friend had incurred the enmity of a rich man, whom he called Frez on his side, and that this had been brought about unwittingly through me. For this is a curious fact: not everything on this new world is three days in advance of ours. Often it happened that the earth was in advance, and I was able, in our exchanges, to tell him things that were happening here which had not yet occurred in Neo, with the result that he followed my example, and in the space of a year had become a very rich man.
“Colson, as I called him, had a servant, whose name I have never learnt; he was called the equivalent to ‘helper,’ and I guess, rather than know, that he is a much younger man than my double, for he said that he had been to school as a pupil of Colson’s. He too learnt quickly; and if there is any difference in the two worlds, it is a keener intelligence: they are more receptive, quicker to grasp essentials.
“There are necessarily certain differences in their methods of government, but these differences are not vital. In Neo men are taught the use of arms, and receive their guerdon of citizenship (which I presume is the vote) only on production of a certificate of proficiency. But in the main their lives run parallel with ours. The very character of their streets, their systems of transportation, even their prison system, are replicas of those on this earth. The main difference, of course, is that their one language is universal. I intend at a later date writing at greater length on the institutions of Neo, but for the moment it is necessary that I should set down particulars of the machines and apparatus employed by me in communicating with our neighbours…”
Here followed twenty closely-written pages of technical description. Tim folded the manuscript and looked around at the astonished faces. Stamford was the first to break the silence.
“Preposterous!” he spluttered. “Impossible! Absurd!…It’s a nightmare! Another world — good God!”
“I believe every word of it.” It was Sir Charles’s quiet voice that stilled the agitated lawyer. “Of course, that is the speck by the side of the corona! Not the world which poor Colson found, but the moon of that world.”
“But couldn’t it be visible at some time?”
Sir Charles shook his head. “Not if it followed the exact orbit of the earth and was placed directly opposite — that is to say, immediately on the other side of the sun. It might overlap at periods, but in the glare of the sun it would be impossible to see so tiny an object. No, there is every possibility that Colson’s story is stark truth.”
He took the manuscript from Tim’s hand and read rapidly through the technical description.
“With this,” he said, touching the paper, “we shall be able to get into communication with these people. If we only had the vocabulary!” he groaned.
“I am afraid you will never hear from Neo again, sir,” said Tim quietly, and told of that brief but poignant minute of conversation he had had before the cry of the dying servant, and the crash of broken instruments, had brought the voice to an abrupt end.
After the lawyer and the scientist had departed, he went with Elsie into the instrument room, and they gazed in silence upon the motionless apparatus.
“The link is broken,” he said at last; “it can never be forged again, unless a new Colson arrives on both earths.”
She slipped her arm in his.
“Aren’t you glad?” she asked softly. “Do you want to know what will happen tomorrow
