Oddly enough, that reflection decided Clo to act. For the moment, fear left her free. She stepped briskly over the window sill with one foot, and landed on the ledge. It felt solid, almost comforting; but as she groped for it with the other foot, horror caught her again, poured through her veins like iced water and made her heart feel a dead thing. She tried not to think of anything except that kind curtain flapping in the wind. She clung to the window-frame with fingers so damp that they slipped on the stone. Holding on for dear life--yes, life was dear, now it hung by a thread!--she edged along, her cheek scraping the wall as she moved. One step, two, three--another would take her so far that she must let go of the window frame. Could she reach the blowing curtain? A few moments ago it had seemed to beckon. Now she depended on it the white folds eluded her hand. If the wind dropped, she was lost. She couldn't help thinking of all the things she wished not to think of. She thought of that immense depth below her narrow perch. She didn't believe the man or woman lived strong-minded enough to forget it! As she reached out with her free arm for the curtain, a light sprang up from the room she had left. O'Reilly was there, searching for her. It had been simple to say, while she stood on a solid floor, that he would not look out of the window. But he might look out: he might hear her feet shuffling along the ledge. If his head appeared now, she would fall. The girl began to shake all over like a winter leaf on a high branch. She would have to go, she thought. But the curtain was blowing very near, so near that she ventured another step. The lace brushed her fingers. With a last effort she grasped a fold. Courage came back. Now she had let go of O'Reilly's window frame. She had passed on beyond hope of return, and yet she had no firm grasp upon the curtain. Before it could give the support a rope gives a climber, she must slowly, patiently, draw it toward her inch by inch until she had it taut. "Angel, are you praying for me?" she wondered. Because she could not pray for herself. She could only count. Dimly, she felt it odd that it should calm her nerves to count each time her fingers closed upon the curtain. But it did calm them.
