Then the dog stopped and turned to look back at him again. He had to search for several moments before he saw the cave. They were directly in front of it. There were bushes and overhanging vines over the entrance, and the opening was smaller than he’d thought it would be—more a fissure, really. A slantwise path led from it down into what seemed to be the last of the low hills. If the moonlight had not been so bright he wouldn’t have seen it at all.

His hands weren’t entirely steady. He look a number of slow, deep breaths and felt his heart’s hard beating ease. He swung down off the horse and stood beside Cavall in the snow. He looked at the cave. He was very much afraid.

Drawing another breath, he turned back to the horse. He stroked its nose, his head close, feeling the warmth. Then he took the reins and turned the horse around to face the hills and the town beyond. “Go now,” he said, and slapped it on the rump.

A little surprised at how easy it was, he watched the stallion canter off, following its own clear track. He could see it a long way in the clear light before the path they had taken curved south around a slope. For a few seconds more he stood gazing west at the place where it had disappeared.

“Well,” he said, turning away, “here goes.” The dog was sitting in the snow, watching him with its liquid eyes. So much sadness there. He had an impulse to embrace it, but the dog wasn’t his, they had shared nothing, and he would not presume. He made a gesture with his hand, a silly one really, and, saying nothing more, walked into Dun Maura.

This time he didn’t look back. There would be only Cavall to see, and the dog would be watching him, motionless in the moonlit snow. Kevin parted the ferns and stepped through the bushes into the cave.

Immediately it was dark. He hadn’t brought any sort of light, so he had to wait for his eyes to adjust. As he waited, he became aware of how warm it suddenly was. He removed his coat and dropped it by the entrance, though a little out of the way. After a moment’s hesitation he did the same with the beautifully woven vest Diarmuid had given him. His heart jumped at a quick flapping sound outside, but it was only a bird. Once it called, then twice, a long, thin, quavering note. Then, a moment later, it called a third time, a half-tone deeper, and not so long. With a hand on the right side wall, Kevin began moving forward.
