There was a sudden hiss of escaping steam, and the whole of the dropped trellis-work was enveloped in mist. The mass seemed to move as if it had been endowed with life or as if a strong breeze had swept over it. Then without the slightest warning a grip like a vice caught Isa Benstein below and above the elbow, pressing her forearm and causing her to wince with the horrible pain. So tight was the grip that she could not turn or move. She stood there writhing in agony, and yet too fascinated to call out. The bones creaked and cracked, and still the pain grew greater; it seemed impossible that any human fingers could grip flesh and blood like that. Were all the weird legends clinging round the Cardinal Moth true, Isa Benstein caught herself wondering in a faint, dizzy way? Then she braced herself up and struggled violently. It was characteristic of the woman that she uttered no cry. As she drooped and her eyes grew cloudy she had a faint vision of a face under a turban, and then there came a sound of swiftly rushing feet. The platform seemed to rise with a sudden jerk. Isa Benstein was wrenched from her feet, the weight of her body told, the arm came away with a cruel drag from the vice-like grip, and she fell a huddled, shimmering heap on the floor. "I hope you are not much hurt," a voice whispered in her ear. "It was dreadful." Isa Benstein scrambled to her feet breathless, dizzy, and writhing with pain. But her quick eyes were clear now, and she recognised the Shan’s companion, whom she knew to be Angela’s lover. His face was white and quivering; there was a nameless horror in his eyes. "You saw it," Mrs. Benstein said. "What was it?" "I cannot tell you yet," Harold said. "It was too dreadful, too awful. The shock of discovery almost unmanned me for a moment. We will speak about that presently. How did you happen to be just where you stood?" "I was admiring the flowers. Sir Clement pulled down the frame for me, so that I could see better. He went away to get something that he wanted to show me, then there was that sudden grip." "Which seemed to come out of a vapouring mist, did it not?" Harold asked hoarsely. "By accident I loosened the spring, and as the frame rose your weight released you. Is not that so?" Mrs. Benstein nodded; she had no words just for the moment. Now that the reaction had come she was feeling sick and faint with the pain. Harold’s eyes were still distended with the horror of some awful discovery. "It is very strange," he said. "Sir Clement did not mean to come back to you, for he has just left the house. He slipped out with some companion whose face I did not see. But your arm is painful. Nothing broken, I hope?" Isa Benstein raised her lovely white arm to prove that such was not the case. But there was a round red band, and here and there a thin red stream came from the broken skin.
