When the World Shook by H. Rider Haggard — Read

That night we slept well and without fear, being quite certain that after their previous experience the Orofenans would make no further attempts upon us. Indeed our only anxiety was for Tommy, whom we could not find when the time came to give him his supper. Bastin, however, seemed to remember having seen him following the Glittering Lady into the cave. This, of course, was possible, as certainly he had taken an enormous fancy to her and sat himself down as close to her as he could on every occasion. He even seemed to like the ancient Oro, and was not afraid to jump up and plant his dirty paws upon that terrific person's gorgeous robe. Moreover Oro liked him, for several times I observed him pat the dog upon the head; as I think I have said, the only human touch that I had perceived about him. So we gave up searching and calling in the hope that he was safe with our supernatural friends.

The next morning quite early the Lady Yva appeared alone; no, not alone, for with her came our lost Tommy looking extremely spry and well at ease. The faithless little wretch just greeted us in a casual fashion and then went and sat by Yva. In fact when the awkward Bastin managed to stumble over the end of her dress Tommy growled at him and showed his teeth. Moreover the dog was changed. He was blessed with a shiny black coat, but now this coat sparkled in the sunlight, like the Lady Yva's hair.
