In White Raiment

by William Le Queux

As I went upstairs I found a letter lying upon the hall table in the place where the guests’ letters were placed. Barton had, I suppose, driven into Corsham and brought with him the mail which would, in the usual course, have been delivered on the following morning. The note was from Hoefer, a couple of awkwardly scribbled lines asking me to come and see him without a moment’s delay.

Eager to hear whether the queer old fellow had made any discovery, I departed next morning by the eight o’clock express for London, having left a note with Beryl’s maid explaining the cause of my sudden journey, and soon after eleven was seated with the old German in his lofty laboratory. The table was, as usual, filled with various contrivances—bottles of liquids and test-tubes containing fluids of various hues—while before him, as I entered, a small tube containing a bright blue liquid was bubbling over the spirit-lamp, the heat causing the colour to gradually fade.

“Ah, my frient,” he said, with his strong accent, holding out his big fat hand encased in a stout leather glove, “I am glad you have come—very glad. It has been a long search, but I haf discovered something, after all. You see these?”—and he indicated his formidable array of retorts and test-tubes. “Well, I have been investigating at Gloucester Square, and have found the affair much more extraordinary than I believed.”

“And you have discovered the truth?” I demanded.

“Yes,” he responded, turning down the flame of the lamp and bending attentively to the bubbling fluid from which all colour had disappeared while I had been watching. “Shall I relate to you the course of my investigations?”

“Do. I am all attention.”

“Well,” he said, leaning both elbows upon the table and resting his chin upon his hands, while the tame brown rat ran along the table and scrambled into his pocket, “on the first evening you sought my assistance I knew, from the remote effects which both of us experienced, that the evil influence of that mysterious visitor in black, was due to some unknown neurotic poison. It was for that reason that I was enabled to administer an antidote without making an exact diagnosis. Now, as you are well aware, toxicology is a very strange study. Even common table-salt is a poison, and has caused death. But my own experiments have proved that, although the various narcotic poisons produce but little local change, their remote effects are very remarkable. Certain substances affect certain organs in particular. The remote action of a poison may be said to be due, in every instance, to its absorption into the veins or lymphatics, except when there is a direct continuity of effect traceable from the point where the poison was applied to the point where the remote effect is shown. It is remarkable that the agents which most affect the nervous system do not act at all when applied to the brain or trunks of nerves. Poisonous effects result from absorption of the poisoning body, and absorption implies solution; the more soluble, therefore, the compound is, the more speedy are its effects. Do you follow me?”

“Quite clearly.”

“The rapid, remote effect produced on leaving that room made it plain that I must look for some powerful neurotic poison that may be absorbed through the skin,” he went on. “With this object I searched microscopically various objects within and without the room, but for a long time was unsuccessful, when, one morning, I made a discovery that upon the white porcelain handle of the door a little colourless liquid had been applied. Greater part of it had disappeared by constant handling, but there was still some remaining on the shaft of the handle, and the microscope showed distinct prism-shaped crystals. All these I secured, and with them have since been experimenting. I found them to be a more deadly poison than any of the known paralysants or hyposthenisants, with an effect of muscular paralysis very similar to that produced by curare, combined with the stiffness about the neck and inability to move the jaws so apparent in symptoms provoked by strychnia. The unknown substance—a most deadly, secret poison, and, as I have since proved, one of those known to the ancients—had been applied to the door-handle on the inside, so that any person in pulling open the door to go out must absorb it in sufficient quantity to prove fatal. Indeed, had it not been for the antidote of chlorine and the mixed oxides of iron which I fortunately hit upon, death must have ensued in the case of each of us.

“To determine exactly what was the poison used was an almost insurmountable task, for I had never met with the substance before; but, after working diligently all this time, I have found that by treating it with sulphuric acid it underwent no change, yet by adding a fragment of bichromate of potassium a series of blue, violet, purple, and red tints were produced, very similar to those seen in the tests for strychnia. The same results were brought about, also, by peroxide of lead and black oxide of manganese. I dried the skin of a frog and touched it with a drop of solution containing a single one of the tiny crystals, when strong tetantic convulsions ensued and the animal died in ten seconds. At last, however, after many other experiments, the idea occurred to me that it was an alkaloid of some plant unknown in modern toxicology. I was, of course, aware of the action of the calabar bean of the West Coast of Africa, the akazga, the datura seeds of India, and such-like poisons, but this was certainly none of these. It was a substance terribly deadly—the only substance that could strike death through the cuticle—utterly unknown to us, yet the most potent of all secret poisons.”
