One of them is dead or dying, thought I.

On reaching the azotea—which I did in a few seconds of time—I found perfect silence there. I saw no one, male or female, living or dead! True, the place was like a garden, with plants, shrubs, and even trees growing in gigantic pots. I could not view it all at once. They might still be there behind the screen of leaves?

I ran to and fro over the whole roof; I saw flower-pots freshly broken. It was the crash of them I had heard while coming up. I saw no man, neither Holingsworth nor Ijurra! They could not be standing up, or I should have seen them. “Perhaps they are down among the pots—both. There were two shots. Perhaps both are down—dead.”

But where was she who screamed? Was it Isolina?

Half distracted, I rushed to another part of the roof. I saw a small escalera—a private stair—that led into the interior of the house. Ha! they must have gone down by it? she who screamed must have gone that way?

For a moment I hesitated to follow; but it was no time to stand upon etiquette; and I was preparing to plunge down the stairway, when I heard shouting outside the walls, and then another shot from a pistol.

I turned, and stepped hastily across the azotea in the direction of the sounds. I looked over the parapet. Down the slope of the hill two men were running at the top of their speed, one after the other. The hindmost held in his hand a drawn sabre. It was Holingsworth still in pursuit of Ijurra!

The latter appeared to be gaining upon his vengeful pursuer, who, burdened with his accoutrements, ran heavily. The Mexican was evidently making for the woods that grew at the bottom of the hill; and in a few seconds more he had entered the timber, and passed out of sight. Like a hound upon the trail, Holingsworth followed, and disappeared from my view at the same spot.

Hoping I might still be able to prevent the shedding of blood, I descended hastily from the azotea, mounted my horse, and galloped down the hill.

I reached the edge of the woods where the two had gone in, and followed some distance upon their trail; but I lost it at length, and came to a halt.
