The man was holding her by the left wrist in a left-handed grip. He was cruelly twisting her wrist and suddenly she cried out again in pain and despairing helplessness.
The blood started mounting to Corriston's temples. He began tugging at the grate with both hands, exerting all his strength in a desperate effort to dislodge it. It began to move a little, to become less firmly attached to the wall. He could feel it moving under his hands, rasping and creaking as it loosened inch by inch.
He was covered with sweat. Already in his mind he had killed the man, and Helen Ramsey was tight in his arms, happy and alive.
The man did not seem to hear the rasp of the grate coming loose. He neither turned nor raised his head. His free hand had gone out and across the girl's face. But if he had struck her on the face, she gave no sign. She did not recoil as if from a blow and there was something strange about the movement. It was as if the man had reached out to tear something from the girl's face—a veil or a mask.
His hand whipped back empty but his fingers were oddly twisted, as if he had clawed at something that had failed to come free.
Corriston pulled back his shoulders and his posture on the ladder grew more erect. He knew that his exertions might send the ladder toppling but it was a risk he had to take.
The grate was freely movable now. He could move it backwards and forwards, six or eight inches each way; but he still could not rip it completely free.
He kept on tugging, his neck cords bulging, the ladder swaying dangerously. The grate could be moved upward now, just a little. No, it was finally coming completely loose. He could move it in all directions and even push it outward at right angles to its base.
Twice he heard Helen Ramsey cry out again, and her screams became a goad that turned his wrists to steel. With a sudden, convulsive wrench he twisted the grate sideways. It came loose in his hands. It was so surprisingly light that an incongruous rage surged up in him. It was cruelly perverse, intolerable, that he should have been so long delayed by a thin sheet of metal that hardly seemed to have any weight at all.
He swung about on the ladder and let the grate drop. It struck the floor a few feet from the Selector and rebounded with a clang loud enough to wake the dead. The ladder swayed again, and he had to grab the edge of the aperture quickly and with both hands to keep himself from toppling.
