But at that same moment he thought of little Concha up aloft and the bitterness died out of his heart as quickly as it had come. No, the play was not yet played out, and it had been no farce. There was yet other work for him--perhaps another life better than this cut-and-thrust existence, ever at the mercy of bullet and sword's point. He stood up straight and listened, hearing for the first five minutes nothing but the soft wind of the night among the leaves, and from the town the barking of the errant and homeless curs which, in the streets and gutters, yelped, scrambled, and tore at each other for scraps of offal and thrice-gnawed bone. From above came the contented twitter of a swallow nestling under the leaves, yet with a curious carrying quality in it too, at once low and far-reaching. It was the Sergeant's signal for his attempt. Rollo set his teeth hard, thought of Concha, bent his head low, and, like a swift-drifting shadow, sped silently across the smooth upland turf. The thick leaves of the laurel parted before him, the sword-flower of Spain pricked him with its pointed leaves, and then closed like a spiked barrier behind him. A blackbird fled noisily to quieter haunts. The frogs ceased their croaking. Panting, Rollo lay still under the branches, crushing out the perfume of the scrubby, scented geranium, which in the watered wildernesses of La Granja takes root everywhere. But among the leaves nothing moved hand or foot against him. Nor gipsy nor mountaineer stirred in the thicket. So that when Rollo, after resting a little, explored quietly and patiently the little plantation, going upon all fours, not a twig of pine crackling under his palms, no hostile knife sheathed itself between his ribs. For, as was now clear, the gipsies had not concealed themselves among the bushes. They had all night before them in which to carry out their projects. Doubtless (thought the young man) they had gone to possess themselves of the town. After that the palace would lie at their mercy, a nut to be cracked at their will. From the first Rollo was resolved to find the little pavilion of which La Giralda had spoken. It was in his mind that the girl might, if free and unharmed, as he hoped, make her way thither. He had indeed only the most vague and general idea of its locality. The old gipsy had told him that it was near to the northern margin of the gardens, and that by following the mountain stream which supplied the great waterfall he could not fail to come upon it. But ere he had ventured forth from his hiding-place, he heard again the swallow's twitter, louder than before, and evidently meant for his ear. Could it be a natural echo or his own disordered fancy which caused a whistle exactly similar to reach him from the exact locality he meant to search?
