"Have you ever seen the castle, Dias?"
"I have seen it, señor. There is only one point from which it is visible. We shall go there to-morrow, it is ten miles from here. The castle lies in a rift of the rock. I should say that in ancient times this opened to the sea, but the building closed the entrance. Whatever it may have been, it does not rise above the summit of the cliff, which goes down as straight as a wall for miles on the sea-face. The rift on the land side of the castle seems to have a width of about fifty feet, and I could see openings which were, I suppose, windows. The rocks on each side are higher than the castle itself, so that anyone coming along would not see it until he looked down upon it."
"But of course it is visible from the sea, Dias?"
"It would have been visible in the old days without a doubt, señor, but it cannot be seen now. The stones are the colour of the rocks beside them. They are stained and broken, and unless a boat went along within a very short distance none would dream that there was a break in the cliff there. I heard that from a fisherman whose boat was driven in by a gale and well-nigh lost. He said that he could see that the stones, which are very large—much larger than any of those in the remains of the buildings of the Incas—were not in regular lines."
"It is very strange that anyone should have taken the trouble to build a place in such a singular position. Is there not any legend as to its construction?"
"There is a tradition, señor, that it was built as a prison, by the king of those times, a thousand years before the Spaniards came, and even before the people whom the Incas conquered came into the land, and that it was a place of imprisonment, some say of a wife, others of a son, who had rebelled against him. Some say that it was built by the demons, but as it happened long before our people came here, none can know."
"Well, Dias, it seems to me that this old place is very likely to have been used as a hiding-place for treasure. As to these tales about demons, of course they are ridiculous. I took your advice when we were being opposed by fierce Indians, but when it is a question of demons, I can trust to my revolvers and rifles against a legion of them."
"Well, señor, you are the master. I have led you here as I promised. There may be treasure here or there may not. If you will go, you must; but I pray you not to command me to go with you. I would have followed you to the death through the swamps and forests on the other side, but I dare not risk being torn to death by demons and being left without burial."
"I do not press you to go, Dias. I respect your convictions, though I do not share in them. I have had a year of travel with you, and we have had many adventures together. This will be my last before I return home. Here at least there seems to me a chance of finding treasure, an infinitely better chance than any we have had, except in the gold valley. Here is a mysterious castle, of whose very existence the Spaniards seem never to have heard. It is just the place where treasure might be hidden. If it has guardians, they must be human, and also there can be but few. The urgent necessity for secrecy was so great, that it must, like all the other secrets, have been confided to a few only. Maybe but one or two old men are there, of whom certainly I need not be afraid. I have told you why I came here, and why I feel so anxious to find a valuable mine, or part of the lost treasures of the Incas. So far I have failed altogether, and I should be a fool as well as a coward were I not ready to run some slight risk in searching this mysterious castle."
"So be it, señor. I say not that you may not succeed. It may be that the demons have no power over white men. If you go and return safely I will go with you, and, should you find treasure, aid you to carry it away. I will lead you to within two miles of it, and will wait three days for your return. If you come not then, I will return to my place and mourn for you."
