“Great burning!” he exclaimed. “What on earth are you getting at now? It is madness. Do you mean to tell me that you think there is some connection between a swarm or two of bees that have turned nasty, a cross dog, and a wicked old barn-door cock and these poor people that have been pitched over the cliffs and hammered to death on the road? There’s no sense in it, you know.”

“I am strongly inclined to believe that there is a great deal of sense in it,” replied Remnant, with extreme calmness. “Look here, Lewis, I saw you grinning the other day at the club when I was telling the fellows that in my opinion all these outrages had been committed, certainly by the Germans, but by some method of which we have no conception. But what I meant to say when I talked about inconceivables was just this: that the Williams’s and the rest of them have been killed in some way that’s not in theory at all, not in our theory, at all events, some way we’ve not contemplated, not thought of for an instant. Do you see my point?”

“Well, in a sort of way. You mean there’s an absolute originality in the method? I suppose that is so. But what next?”

Remnant seemed to hesitate, partly from a sense of the portentous nature of what he was about to say, partly from a sort of half-unwillingness to part with so profound a secret.

“Well,” he said, “you will allow that we have two sets of phenomena of a very extraordinary kind occurring at the same time. Don’t you think that it’s only reasonable to connect the two sets with one another.”

“So the philosopher of Tenterden steeple and the Goodwin Sands thought, certainly,” said Lewis. “But what is the connection? Those poor folks on the Highway weren’t stung by bees or worried by a dog. And horses don’t throw people over cliffs or stifle them in marshes.”

“No; I never meant to suggest anything so absurd. It is evident to me that in all these cases of animals turning suddenly savage the cause has been terror, panic, fear. The horses that went charging into the camp were mad with fright, we know. And I say that in the other instances we have been discussing the cause was the same. The creatures were exposed to an infection of fear, and a frightened beast or bird or insect uses its weapons, whatever they may be. If, for example, there had been anybody with those horses when they took their panic they would have lashed out at him with their heels.”

“Yes, I dare say that that is so. Well.”

“Well; my belief is that the Germans have made an extraordinary discovery. I have called it the Z Ray. You know that the ether is merely an hypothesis; we have to suppose that it’s there to account for the passage of the Marconi current from one place to another. Now, suppose that there is a psychic ether as well as a material ether, suppose that it is possible to direct irresistible impulses across this medium, suppose that these impulses are towards murder or suicide; then I think that you have an explanation of the terrible series of events that have been happening in Meirion for the last few weeks. And it is quite clear to my mind that the horses and the other creatures have been exposed to this Z Ray, and that it has produced on them the effect of terror, with ferocity as the result of terror. Now what do you say to that? Telepathy, you know, is well established; so is hypnotic suggestion. You have only to look in the ‘Encyclopædia Britannica’ to see that, and suggestion is so strong in some cases as to be an irresistible imperative. Now don’t you feel that putting telepathy and suggestion together, as it were, you have more than the elements of what I call the Z Ray? I feel myself that I have more to go on in making my hypothesis than the inventor of the steam engine had in making his hypothesis when he saw the lid of the kettle bobbing up and down. What do you say?”

Dr. Lewis made no answer. He was watching the growth of a new, unknown tree in his garden.
