"The long and the short of it is," Mr. Remnant concluded, "that any one of us may be the murderer, though he hasn't the faintest notion of the fact. Take Llewelyn there."
Mr. Payne Llewelyn was an elderly lawyer, a rural Tulkinghorn. He was the hereditary solicitor to the Morgans of Pentwyn. This does not sound anything tremendous to the Saxons of London; but the style is far more than noble to the Celts of West Wales; it is immemorial; Teilo Sant was of the collaterals of the first known chief of the race. And Mr. Payne Llewelyn did his best to look like the legal adviser of this ancient house. He was weighty, he was cautious, he was sound, he was secure. I have compared him to Mr. Tulkinghorn of Lincoln's Inn Fields; but Mr. Llewelyn would most certainly never have dreamed of employing his leisure in peering into the cupboards where the family skeletons were hidden. Supposing such cupboards to have existed, Mr. Payne Llewelyn would have risked large out-of-pocket expenses to furnish them with double, triple, impregnable locks. He was a new man, an advena, certainly; for he was partly of the Conquest, being descended on one side from Sir Payne Turberville; but he meant to stand by the old stock.
"Take Llewelyn now," said Mr. Remnant. "Look here, Llewelyn, can you produce evidence to show where you were on the night those people were murdered on the Highway? I thought not."
Mr. Llewelyn, an elderly man, as I have said, hesitated before speaking.
"I thought not," Remnant went on. "Now I say that it is perfectly possible that Llewelyn may be dealing death throughout Meirion, although in his present personality he may not have the faintest suspicion that there is another Llewelyn within him, a Llewelyn who follows murder as a fine art."
Mr. Payne Llewelyn did not at all relish Mr. Remnant's suggestion that he might well be a secret murderer, ravening for blood, remorseless as a wild beast. He thought the phrase about his following murder as a fine art was both nonsensical and in the worst taste, and his opinion was not changed when Remnant pointed out that it was used by De Quincey in the title of one of his most famous essays.
"If you had allowed me to speak," he said with some coldness of manner, "I would have told you that on Tuesday last, the night on which those unfortunate people were murdered on the Highway I was staying at the Angel Hotel, Cardiff. I had business in Cardiff, and I was detained till Wednesday afternoon."
Having given this satisfactory alibi, Mr. Payne Llewelyn left the club, and did not go near it for the rest of the week.
Remnant explained to those who stayed in the smoking room that, of course, he had merely used Mr. Llewelyn as a concrete example of his theory, which, he persisted, had the support of a considerable body of evidence.
"There are several cases of double personality on record," he declared. "And I say again that it is quite possible that these murders may have been committed by one of us in his secondary personality. Why, I may be the murderer in my Remnant B. state, though Remnant A. knows nothing whatever about it, and is perfectly convinced that he could not kill a fowl, much less a whole family. Isn't it so, Lewis?"
Dr. Lewis said it was so, in theory, but he thought not in fact.
"Most of the cases of double or multiple personality that have been investigated," he said, "have been in connection with the very dubious experiments of hypnotism, or the still more dubious experiments of spiritualism. All that sort of thing, in my opinion, is like tinkering with the works of a clock—amateur tinkering, I mean. You fumble about with the wheels and cogs and bits of mechanism that you don't really know anything about; and then you find your clock going backwards or striking 240 at tea-time. And I believe it's just the same thing with these psychical research experiments; the secondary personality is very likely the result of the tinkering and fumbling with a very delicate apparatus that we know nothing about. Mind, I can't say that it's impossible for one of us to be the Highway murderer in his B. state, as Remnant puts it. But I think it's extremely improbable. Probability is the guide of life, you know, Remnant," said Dr. Lewis, smiling at that gentleman, as if to say that he also had done a little reading in his day. "And it follows" therefore, that improbability is also the guide of life. When you get a very high degree of probability, that is, you are justified in taking it as a certainty; and on the other hand, if a supposition is highly improbable, you are justified in treating it as an impossible one. That is, in nine hundred and ninety-nine cases out of a thousand."
"How about the thousandth case?" said Remnant. "Supposing these extraordinary crimes constitute the thousandth case?"
The doctor smiled and shrugged his shoulders, being tired of the subject. But for some little time highly respectable members of Porth society would look suspiciously at one another wondering whether, after all, there mightn't be "something in it." However, both Mr. Remnant's somewhat crazy theory and Dr. Lewis's plausible theory became untenable when two more victims of an awful and mysterious death were offered up in, sacrifice, for a man was found dead in the Llanfihangel quarry, where the woman had been discovered. And on the same day a girl of fifteen was found broken on the jagged rocks under the cliffs near Porth. Now, it appeared that these two deaths must have occurred at about the same time, within an hour of one another, certainly; and the distance between the quarry and the cliffs by Black Rock is certainly twenty miles.
"A motor could do it," one man said.
But it was pointed out that there was no high road between the two places; indeed, it might be said that there was no road at all between them. There was a network of deep, narrow, and tortuous lands that wandered into one another at all manner of queer angles for, say, seventeen miles; this in the middle, as it were, between Black Rock and the quarry at Llanfihangel. But to get to the high land of the cliffs one had to take a path that went through two miles of fields; and the quarry lay a mile away from the nearest by-road in the midst of gorse and bracken and broken land. And, finally, there was no track of motor-car or motor-bicycle in the lanes which must have been followed to pass from one place to the other.
"What about an airplane, then?" said the man of the motor-car theory. Well, there was certainly an aerodrome not far from one of the two places of death; but somehow, nobody believed that the Flying Corps harbored a homicidal maniac. It seemed clear, therefore, that there must be more than one person concerned in the terror of Meirion. And Dr. Lewis himself abandoned his own theory.
"As I said to Remnant at the Club," he remarked, "improbability is the guide of life. I can't believe that there are a pack of madmen or even two madmen at large in the country. I give it up."
And now a fresh circumstance or set of circumstances became manifest to confound judgment and to awaken new and wild surmises. For at about this time people realized that none of the dreadful events that were happening all about them was so much as mentioned in the Press. I have already spoken of the fate of the Meiros Observer. This paper was suppressed by the authorities because it had inserted a brief paragraph about some person who had been "found dead under mysterious circumstances"; I think that paragraph referred to the first death of Llanfihangel quarry. Thenceforth, horror followed on horror, but no word was printed in any of the local journals. The curious went to the newspaper offices—there were two left in the county—but found nothing save a firm refusal to discuss the matter. And the Cardiff papers were drawn and found blank; and the London Press was apparently ignorant of the fact that crimes that had no parallel were terrorizing a whole countryside. Everybody wondered what could have happened, what was happening; and then it was whispered that the coroner would allow no inquiry to be made as to these deaths of darkness.
