Hill drew her to a large flat rock on the edge of the path. "Sit down," he said.

She did so, and he took up his stand beside her, one foot lodged upon the stone. In the silence that followed she was aware of his eyes upon her, intently watching her face. She gripped her hands hard around her knees, enduring his scrutiny with a fast-throbbing heart. She expected some curt, soul-searching question at the end of it. But none came. Instead, the noise that reverberated through the valley suddenly ceased, and there fell an intense stillness.

That racked her beyond bearing. She looked up at him at last with a desperate courage and met his eyes. "What is it?" she questioned. "Why do you—why do you look at me—like that?"

He made a brief gesture, as if refusing a challenge, and stood up. "Shall we go?" he said.

She got up also, but her knees were trembling, and in a moment his hand came out and closed with that official grip upon her elbow. He led her to the mine entrance guiding her over the rough ground in utter silence.

They left the daylight behind them, passing almost immediately into semi-darkness. Some rough steps hewn in the rock led down into a black void before them.

"Are there no lights anywhere?" said Dot.

"Yes. There'll be a lamp round the corner. Straight on down!" said Fletcher.

But for his presence she would hardly have dared it, so great was the horror that this place had inspired within her. But to wait alone with him in that terrible empty valley was even less endurable. She went down the long, steep stair without further protest.

They reached the foot at length, and a dim light shone ahead of them. The atmosphere was vault-like and penetratingly damp. The passage divided almost immediately, and a narrow track led off between black walls of stone to the right, where in the distance another lamp shone.
