The Haunting of Low Fennel. Sax Rohmer

      Major Dale’s eyes began to protrude, and:—

      “Addison,” he said hoarsely—“don’t joke about it!—don’t joke. It was not a grey vapour that strangled Seager....”

      “Certainly it was not. Seager was strangled by some wholly inoffensive person—we shall probably never know his identity—who had fallen asleep amongst the bushes on the mound, close beside the house....”

      “But man alive! I’ve seen the beastly thing, with my own eyes! You’ve seen it! Wales saw it! Mrs. Ord saw it!...”

      “Mrs. Ord saw her husband.”

      “Ah! you’re coming round to my belief about the Ords!”

      “Decidedly I am.”

      “But what did Wales see—eh? And what did I see!”

      “You saw the vapour in operation.”

      The Major fell back in his chair with an expression upon his face which I cannot hope to describe. Words failed him altogether.

      “I had come prepared for something of the sort,” I continued rapidly; “for I have investigated several cases of haunting—notably in the Peak district—which have proved to be due to an emanation from the soil—a vapour. But the effect of such vapour, in the other cases, was to induce delusions of sight, in nearly every instance (although, in two, the delusions were of hearing).

      “In other words, the person affected by this vapour was drugged, and, during the drugged state, perceived certain visions. I made the mistake, at first, of supposing that Low Fennel came within the same category. The classical analogy, of course, is that of the Sibyls, who delivered the oracular responses from the tripod, under the afflatus of a vapour said to arise from the sacred subterranean stream called Kassotis. The theory is, therefore, by no means a new one!”

      Major Dale stared dully, but made no attempt to interrupt me.

      “There are probably many spots, in England alone,” I continued, “thus affected; but, fortunately, few of them have been chosen as building-sites. Barrows and tumuli of the stone and bronze age, and also Roman shrines, seem frequently to be productive of such emanations. The barrow beside Low Fennel (and now under the new wing) is a case in point.

      “Sudden atmospheric changes seem to be favourable to the formation of the vapour. The barrow in Peel Castle, Isle of Man, is peculiarly susceptible to thunder-storms, for instance, whilst that at Low Fennel emits a vapour only after a spell of intense heat, and at the exact moment when the temperature begins to fall again. In the case of a sustained heat-wave, this would take place at some time during each night.

      “And now for the particular in which the vapour at Low Fennel differs from other, similar emanations. It is not productive of delusions of sight; it induces a definite and unvarying form of transient insanity!”

      Major Dale moved slightly, but still did not speak.

      “Dame Pryce was the first recorded victim of the vapour. She was accused of witchcraft by a neighbour who testified to having seen her transform herself into a hideous and unrecognizable hag—whereas, in her proper person, she seems to have been a comely old lady. Lack of evidence compels us to dismiss the case of Seager, but consider that of the Ords. The man Ord, on his own confession, had fallen asleep outside the house. He became a victim of the vapour—and his own wife failed to recognize him.

      “To what extent the mania so produced is homicidal remains to be proved; the gas is rare and difficult to procure, so that hitherto analysis has not been attempted. My own theory is that the subject remains harmless provided that, whilst under the mysterious influence, he does not encounter any person distasteful to him. Thus, Seager may have met his death at the hands of some tramp who had been turned away from the house.

      “As to the symptoms: they seem to be quite unvarying. The subject strips, contorts his face out of all semblance to humanity (and always in a particular fashion) and crawls, lizard-like upon the ground, with the head held low, in an attitude of listening. That it is possible so to contort the face as to render it unrecognizable is seen in some cases of angina pectoris, of course.

      “The subject apparently returns to the spot from whence he started and sinks into profound sleep, as is seen in some cases of somnambulism; and—like the somnambulist, again—he acquires incredible agility. How you yourself came, twice, under the influence of the vapour, is easily explained. The first time—when the housekeeper saw you—you had actually been in bed; and the second time, as you have told me, you had gone upstairs, undressed, and then slipped on your dressing-gown in order to complete some work in the study. Instead of completing the work, you dozed in your chair—and we know what followed! In the case of—Mrs. Dale....”

      “God! Addison,” said the Major huskily, and stood up, clutching the chair-arms—“Addison! You are trying to tell me that—what I saw was ... Marjorie!...”

      I nodded gravely.

      “Without letting her suspect my reason for making the inquiries, I learnt that on that last night at Low Fennel, feeling dreadfully lonely and frightened, she determined to run along to the new wing—which seemed a safer place—and to wait in your room until you came up. She fell asleep, and....”

      “Addison ... can a mere ‘vapour’ produce such....”

      “You mean, is the vapour directed or animated, by some discarnate, evil intelligence? My dear Major, you are taking us back to the theory of Elemental spirits, and I blankly refuse to follow you!”
