Jessie felt her dread and horror of the occult surge up in her, and it required all her resolution to remain here. But the call of her love was imperative: if she was to be permitted to help Archie at all, she must learn what it was that possessed him, and find means to combat it. She had to know first what it was, penetrate, so far as her love had power, into the source of it, diagnose it, if she was to help in curing. "What are you going to do?" she said. "It's very simple; you'll soon see. Sit down, Jessie." He went to the window and drew aside the curtains. He put on the table in front of where he was to sit the silver top of some toilet-bottle, and then went to the door and turned out all the electric lights at the switch-board. The moonlight outside, without shining directly into the room, made the objects in it clearly though duskily visible, and Jessie, where she sat with her back to the light, could see Archie's face and outline, when her eyes got accustomed to the dimness, quite distinctly. He sat close to her at the end of the writing-table, and just in front of him glimmered the stopper from the toilet-bottle. "Now I'm going to look at that till I go off into trance," he said. "Watch what happens very closely, for I may go into deep trance, and promise me not to move till I come round again. I daresay you will neither hear nor see anything, but I don't know." For some few minutes, as far as the girl could judge, they sat in silence. Once or twice Archie shifted his position slightly, and she heard his shirt-front creak a little as he breathed quietly and normally. Outside a little wind stirred, and the tassel of the blind tapped against the sill. Then there came a change: his breathing grew louder, as if he panted for air, and now and again he moaned, and she saw his head drop forward. This moaning sound was horrible to hear, and, but for her promise, and the insistent urging of her love, she must have got up and roused him. His breath whistled between his lips as he took it in, and his face seemed to be shining with some dew of anguish, and his arms twisted and writhed as if struggling against some overmastering force. Then suddenly all sign of struggle ceased, he sat bent forward, but perfectly still, and from the table in front of him came three loud, peremptory raps, as of splitting wood. From the dusk of the room came others which she could not localize. Archie raised his head, and, instead of leaning over the table, sank back in his chair, his arms hanging limp by his side. He began to whisper to himself, and soon Jessie caught the words. "Martin, are you here?" he kept repeating. "Martin, are you here? Martin, Martin?"
