"The speaker went to the window, leaving the other still staring fearfully in my direction. Having closed the curtains, the man returned to his place. "'By heaven!' he cried, 'the thing is still there!' And I could see the pallor creeping over his face. "A moment later I heard one of them say, 'It has gone. Well, whatever it was, I have had a shock. I am trembling all over.' And with that he rang the bell. "Presently a footman appeared with a bottle of spirits and a siphon. Having deposited the tray, he chanced to look towards the place where I was sitting. A piercing cry followed, and the man ran screaming out of the room. The two men also started to their feet and began shouting something I could not hear. I suppose they were calling to some person in the house, for the shouts were quickly followed by the entry of a young fellow of athletic build and truculent countenance. "'Show me your damned ghost,' he said, 'and I'll soon settle him.' "'He's over there--in that seat,' cried one. 'For heaven's sake, go up to him, Reginald, and see what he's made of.' "The truculent youth darted forward, but suddenly came to a dead stop, with a face as white as a sheet. Then with a trembling hand he whipped a revolver out of his pocket, and at five paces fired all six barrels point-blank at my body. At each shot I was aware of a painful feeling in the penumbra of my consciousness, like the sudden awakening of a buried sorrow." At this point Panhandle paused to relight his cigar, and I took the opportunity to make a remark. "Count it no grievance," I said, "if one who shoots at psychologists is himself occasionally shot at. I surmise that the truculent youth was the ghost of a promising psychologist, foully murdered by your nefarious gun." "Name it a righteous execution, and I shall agree," he answered. "Or it may be," I added, "that many of the sudden and inexplicable pains that break out in our minds and in our bodies are caused by ghosts, or whatever you call them, shooting at us, or stabbing us, to test our reality." Panhandle turned a keen glance at my face to see if I was serious, and, being satisfied that I was, continued: "I have heard more unlikely explanations of such pains, and your theory is precisely one of those which medical science will have to investigate when these discoveries of mine are made public. But let me resume the narrative. "At the sound of the firing the whole household seemed to be aroused. And what a household it was! In a few moments the room was crowded with beings of reverend countenance and stately carriage. Looking round with slow, grave eyes, they conversed in whispers. 'Science must investigate this,' one of them said. 'We will arrange that a committee of the Society shall make a thorough examination of the house and test the phenomena. Don't forget to engage two shorthand writers and an expert in spirit photography. And let the room be sealed up till the experts arrive.'
