The suddenness of the whole incident was shocking in itself, but that was not all; the mere contrast to what he had looked for was disconcerting, but there was something more; the curious unexpected nature of the request, if request it was, was not without its element of mystery, but above and beyond all else was the thought--the thought that for a dreadful moment held his heart and soul in icy bonds--what sight when he returned to the inner room, as return at once he must, what gruesome sight would meet his eyes? What phantoms his misgivings raised, every man may conjecture for himself. Follow, then, another step in imagination, and having given a somewhat free and ghastly fancy rein, push the chamber door cautiously and inch by inch, or fling it boldly open as you will; then pause upon the threshold, as Hampden did, in sharp surprise. Nothing was altered, no single detail had undergone the slightest change! On the bed, rigid and very sharp beneath the single unclean sheet, lay the body of the mangled man. Not a fold of his shroud-like wrapping differed from its former line, it did not seem possible that a breath had stirred him. Had the voice been a trick of the imagination? Hampden knew, as far as mortal man can be sure of any mortal sense, that the voice had been as real as his life itself. Then----? It occurred to him in a flash: here was the stage of under-consciousness of which Dr Stone had spoken. Of his pain, the accident, where he at that moment lay, and all his real surroundings, the sufferer knew nothing, and never would know. But out of the shock and shattering, some of the delicate machinery of the brain still kept its balance, and would continue to exercise its functions to the end. It was an ordeal, but it had to be done. It was the purpose for which he had been summoned. Sir John moved to the bedside, nerved himself to watch the ashen face, and said slowly and distinctly: "Mr Tubes is not here. Do you wish to see him?" There was just a perceptible pause, and then the bloodless lips replied. But not the faintest tremor of a movement stirred the body otherwise from head to foot, and in the chilling absence of expression the simile occurred to Hampden of bubbles rising from some unseen working to the surface of an inky pool. "I have come on purpose. Let him be told that it is most important." Hampden had to feel his way. The woman had mentioned that Flak was at least on terms of acquaintanceship with Mr Tubes. The doctor had surmised that the man had something he must say before he died. But was this the one true line, or a mere vagary of the sub-conscious state--a twist in the tortuous labyrinth that would lead to nothing? "He is not here at present," he said. "If you will tell me what you wish to say I will write it down, so that it cannot fail to reach him." "No. I cannot tell any one else. I must see him."
