He pulled his stockings over the pants of his pyjamas and put on his velvet working jacket, forgetting for the moment that, if these things were true, it would be perfectly easy for him to make himself invisible to beings in the ordinary world of three dimensions. Then he turned out the light, opened the door very softly, and crept downstairs. Yes, what he had seen was true. He heard the soft, shuffling patter of stockinged feet along the landing, though he could see nothing in the dark. A door opened gently. His sense of location told him that it was the door of the spare bedroom next but one to the study. He felt his way silently and softly along the wall, and as he did so his hand touched the electric switch. Should he turn the light on and alarm the house? Whoever was there had "broken and entered" after midnight, and was therefore outside the law. No, he would not do that. If what he had seen was true, the intruders believed that their mission was a sacred one. No doubt the man was armed, and perhaps the woman also, and what would a knife-stab mean to them on such a desperate quest? As these thoughts ran at lightning speed through his mind, he saw a faint glow inside the room. He crept forward and looked round the side of the doorway. The man had a little electric lamp in his hand and was flashing the slender rays all over the room. He drew his head back quickly as he heard him say: "There is nothing here, Anat. Come, let us try the next room. Neither lock nor bolt nor even human life must stand in the way of our search now that we have begun it!" He heard them coming towards the door. Instinctively he shrank back, and his heart stood still as he thought of what would happen if the man chanced to turn the little ray of his lamp on him. Almost involuntarily his thoughts went back to the promise of Queen Nitocris, and something like a prayer that it might be kept rose to his lips. They came out, and the man flashed the thin electric ray up and down the passage. It wavered hither and thither, and at last fell directly on his face. He was anything but a coward, but he was thinking of Niti--and what if a knife-stab left her undefended? But to his amazement, although they were both looking straight at him, the expression of neither face changed in the slightest. They had not seen him. The Queen had answered his prayer. He was no longer in the world of three dimensions, and so he was invisible to all dwellers in it. For him, then, there was evidently no danger--but Niti----? They moved along to the next door. That was hers. The woman put her hand on the knob and turned it. To his horror, the door opened. She had forgotten to lock it. They both crept in, and he followed them boldly enough now, knowing what he did. The ray leapt rapidly about the room till it fell on the bed with its pale blue silken coverlet, and then on the pillow, on which rested the head of the sleeping, breathing image of the long-dead Queen.
