In spite of himself, some accidental significance in this ostentatious adjuration to lull Pereo's suspicions struck him with pain. But the old man's eyes glittered with gratified passion as he said, "Ay, good! I will keep my word. Thou shalt work thy will on the little one as I have said. Truly it is a Providence! Come!" Seeing Captain Carroll glance round for his overcoat, he seized a poncho from the wall, wrapped it round him, and grasped his hand. Carroll, who would have evaded this semblance of disguise, had no time to parley, and they turned together, through the door by which Pereo had entered, into a long dark passage, which seemed to be made through the outer shell of the building that flanked the park. Following his guide in the profound obscurity, perfectly conscious that any change in his madness might be followed by a struggle in the dark, where no help could reach them, they presently came to a door that opened upon the fresh smell of rain and leaves. They were standing at the bottom of a secluded alley, between two high hedges that hid it from the end of the garden. Its grass-grown walk and untrimmed hedges showed that it was seldom used. Carroll, still keeping close to Pereo's side, felt him suddenly stop and tremble. "Look!" he said, pointing to a shadowy figure some distance before them; "look, 'tis Maruja, and alone!" With a dexterous movement, Carroll managed to slip his arm securely through the old man's, and even to throw himself before him, as if in his eagerness to discern the figure. "'Tis Maruja--and alone!" said Pereo, trembling. "Alone! Eh! And the Coyote is not here!" He passed his hand over his staring eyes. "So." Suddenly he turned upon Carroll. "Ah, do you not see, it is a trick! The Coyote is escaping with Faquita! Come! Nay; thou wilt not? Then will I!" With an unexpected strength born of his madness, he freed his arm from Carroll and darted down the alley. The figure of Maruja, evidently alarmed at his approach, glided into the hedge, as Pereo passed swiftly by, intent only on his one wild fancy. Without a further thought of his companion or even the luckless Faquita, Carroll also plunged through the hedge, to intercept Maruja. But by that time she was already crossing the upper end of the lawn, hurrying towards the entrance to the patio. Carroll did not hesitate to follow. Keeping in view the lithe, dark, active little figure, now hidden by an intervening cluster of bushes, now fading in the gathering evening shadows, he nevertheless did not succeed in gaining upon her until she had nearly reached the patio. Here he lost ground, as turning to the right, instead of entering the court-yard, she kept her way toward the stables. He was near enough, however, to speak. "One moment, Miss Saltonstall," he said hurriedly; "there is no danger. I am alone. But I must speak with you."
