The lemur-thing broke the spell by chattering excitedly. In the very dim starlight he could just discern that it was pointing upward with one paw, an uncannily human gesture. The girl uttered a sharp word and dove toward the treetops, and Eldon looked up in time to see a huge leathery-winged shape swooping silently upon them. He felt the foetid breath and glimpsed hooked talons and a beak armed with incurving teeth as the thing swept by and flapped heavily upward again. The girl released him abruptly, leaving his heart pounding in sudden terrible awareness of his utter helplessness. He felt himself brush against a branch that stood out above the others and start to drift away. But the lemur hooked its hind claws into his shirt and grasped the branch with its forepaws, anchoring him against the wind.

She twisted upright and her feet touched gently as she reached to her belt and regained normal weight. Eldon still floated. The girl pushed him through the air and into a black hole between the spreading roots of a huge tree. The hole slanted downward, twisting and turning, and became a tunnel. The lemur-thing jumped down and scampered ahead. It was utterly dark until she made her hands glow again, after they had passed a bend. Finally the tunnel
