'Come, now, you are acquainted, and she likes you. This will be a most valuable lesson for her. Now, let us have a walk, and you tell me the news, if there is any.'

'Most willingly,' I said, 'for I have much news to tell.'

So we turned back along the path into the quietest part of the garden, I walking by Ruth's side. And I told her of all that had passed between her brother and me in the morning, and of what was to be done on the following night. She was looking very serious when I had finished, and I could see that many unspoken thoughts were working in her mind, and when I had done she looked up at me and said,—

'Laurens's plan seems a very good one at first sight, but of course we cannot decide upon anything until we have thought a good deal more about it, and talked it well over amongst ourselves. But, at anyrate, it would be several weeks yet before I would even think of going away with Golden Star, so there is plenty of time for that. But to-morrow night—Listen, Vilcaroya, may I ask a very great favour of you?'

'Joyful Star can ask no favour of me,' I said. 'She can speak, and I can hear and obey.'

'Nonsense, Vilcaroya! I wish you wouldn't talk like that,' she answered with pretty petulance. 'Now, suppose I was to ask you to let me see this wonderful treasure-house of yours and promise faithfully not to tell anyone about it—would you let me?'

'It is not the best that I can show you,' I answered gladly, 'but if you desire to see it, it is yours and all that it contains. I can give your brother and the professor other gold, and I will show you a greater treasure-house than this under the Fortress itself.'

'Well,' she laughed, 'I won't say now that I won't have it, because the sight of all that gold might be too much for me, but I should dearly love to come and see it, and I think I might venture to bring Golden Star too. She's quite well and strong now, and if we are careful of her, it can't do her any harm, and it may do her good. Shall I bring her?'

'Yes,' I said, 'why not?'

At this moment we saw Djama come walking down the path towards us, and at the sight of him there came to me, like the stab of a dagger of ice, the sudden memory that, at the moment I was speaking of my treasure-house under the Sacsahuaman, I had heard a gentle rustle behind some bushes close by the path, and a sound like that of a stealthy tread.
