"You know," said Lewis, "how a bit of burnt paper will sometimes hang over the coals before it goes up the chimney, and little worms of fire will shoot through it. It was like that, if you should be standing some distance away. Just threads and hairs of yellow light I saw, and specks and sparks of fire, and then a twinkling of a ruby no bigger than a pin point, and a green wandering in the black, as if an emerald were crawling, and then little veins of deep blue. 'Woe is me!' I said to myself in Welsh, 'What is all this color and burning?'
"And, then, at that very moment there came a thundering rap at the door of the room inside, and there was my man telling me that I was wanted directly up at the Garth, as old Mr. Trevor Williams had been taken very bad. I knew his heart was not worth much, so I had to go off directly, and leave Remnant to make what he could of it all."
Chapter VI
Mr. Remnant's Z Ray
Dr. Lewis was kept some time at the Garth. It was past twelve when he got back to his house.
He went quickly to the room that overlooked the garden and the sea and threw open the French window and peered into the darkness. There, dim indeed against the dim sky but unmistakable, was the tall pine with its sparse branches, high above the dense growth of the ilex trees. The strange boughs which had amazed him had vanished; there was no appearance now of colors or of fires.
He drew his chair up to the open window and sat there gazing and wondering far into the night, till brightness came upon the sea and sky, and the forms of the trees in the garden grew clear and evident. He went up to his bed at last filled with a great perplexity, still asking questions to which there was no answer.
The doctor did not say anything about the strange tree to Remnant. When they next met, Lewis said that he had thought there was a man hiding amongst the bushes—this in explanation of that warning gesture he had used, and of his going out into the garden and staring into the night. He concealed the truth because he dreaded the Remnant doctrine that would undoubtedly be produced; indeed, he hoped that he had heard the last of the theory of the Z Ray. But Remnant firmly reopened this subject.
"We were interrupted just as I was putting my case to you," he said. "And to sum it all up, it amounts to this: that the Huns have made one of the great leaps of science. They are sending 'suggestions' (which amount to irresistible commands) over here, and the persons affected are seized with suicidal or homicidal mania. The people who were killed by falling over the cliffs or into the quarry probably committed suicide; and so with the man and boy who were found in the bog. As to the Highway case, you remember that Thomas Evans said that he stopped and talked to Williams on the night of the murder. In my opinion Evans was the murderer. He came under the influence of the Ray, became a homicidal maniac in an instant, snatched Williams's spade from his hand and killed him and the others."
"The bodies were found by me on the road."
"It is possible that the first impact of the Ray produces violent nervous excitement, which would manifest itself externally. Williams might have called to his wife to come and see what was the matter with Evans. The children would naturally follow their mother. It seems to me simple. And as for the animals—the horses, dogs, and so forth, they as I say, were no doubt panic stricken by the Ray, and hence driven to frenzy."
"Why should Evans have murdered Williams instead of Williams murdering Evans? Why should the impact of the Ray affect one and not the other?"
"Why does one man react violently to a certain drug, while it makes no impression on another man? Why is A able to drink a bottle of whisky and remain sober, while B is turned into something very like a lunatic after he has drunk three glasses?"
"It is a question of idiosyncrasy," said the doctor.
"Is idiosyncrasy Greek for 'I don't know'?" asked Remnant.
"Not at all," said Lewis, smiling blandly. "I mean that in some diatheses whisky—as you have mentioned whisky—appears not to be pathogenic, or at all events not immediately pathogenic. In other cases, as you very justly observed, there seems to be a very marked cachexia associated with the exhibition of the spirit in question, even in comparatively small doses."
Under this cloud of professional verbiage Lewis escaped from the Club and from Remnant. He did not want to hear any more about that Dreadful Ray, because he felt sure that the Ray was all nonsense. But asking himself why he felt this certitude in the matter he had to confess that he didn't know. An aeroplane, he reflected, was all nonsense before it was made; and he remembered talking in the early nineties to a friend of his about the newly discovered X Rays. The friend laughed incredulously, evidently didn't believe a word of it, till Lewis told him that there was an article on the subject in the current number of the Saturday Review; whereupon the unbeliever said, "Oh, is that so? Oh, really. I see," and was converted on the X Ray faith on the spot. Lewis, remembering this talk, marveled at the strange processes of the human mind, its illogical and yet all-compelling ergos, and wondered whether he himself was only waiting for an article on the Z Ray in the Saturday Review to become a devout believer in the doctrine of Remnant.
But he wondered with far more fervor as to the extraordinary thing he had seen in his own garden with his own eyes. The tree that changed all its shape for an hour or two of the night, the growth of strange boughs, the apparition of secret fires among them, the sparkling of emerald and ruby lights: how could one fail to be afraid with great amazement at the thought of such a mystery?
Dr. Lewis's thoughts were distracted from the incredible adventure of the tree by the visit of his sister and her husband. Mr. and Mrs. Merritt lived in a well-known manufacturing town of the Midlands, which was now, of course, a center of munition work. On the day of their arrival at Porth, Mrs. Merritt, who was tired after the long, hot journey, went to bed early, and Merritt and Lewis went into the room by the garden for their talk and tobacco. They spoke of the year that had passed since their last meeting, of the weary dragging of the war, of friends that had perished in it, of the hopelessness of an early ending of all this misery. Lewis said nothing of the terror that was on the land. One does not greet a tired man who is come to a quiet, sunny place for relief from black smoke and work and worry with a tale of horror. Indeed, the doctor saw that his brother-in-law looked far from well. And he seemed "jumpy"; there was an occasional twitch of his mouth that Lewis did not like at all.
"Well," said the doctor, after an interval of silence and port wine, "I am glad to see you here again. Porth always suits you. I don't think you're looking quite up to your usual form. But three weeks of Meirion air will do wonders."
"Well, I hope it will," said the other. "I am not up to the mark. Things are not going well at Midlingham."
"Business is all right, isn't it?"
"Yes. Business is all right. But there are other things that are all wrong. We are living under a reign of terror. It comes to that."
"What on earth do you mean?"
"Well, I suppose I may tell you what I know. It's not much. I didn't dare write it. But do you know that at every one of the munition works in Midlingham and all about it there's a guard of soldiers with drawn bayonets and loaded rifles day and night? Men with bombs, too. And machine-guns at the big factories."
"German spies?"
"You don't want Lewis guns to fight spies with. Nor bombs. Nor a platoon of men. I woke up last night. It was the machine-gun at Benington's Army Motor Works. Firing like fury. And then bang! bang! bang! That was the hand bombs."
"But what against?"
"Nobody knows."
