On this day, however, Luisa Valverde mounted up to the azotea with feelings, and under an impulse, very different from that hitherto actuating her. Her behaviour, too, was different. When she made her way up and took stand inside the mirador, her eyes, instead of wandering all around, or resting dreamily on the landscape, with no care for its attractions, were turned in a particular direction, and became fixed upon a single point. This was where the road, running from the city to Tacubaya, alongside the aqueduct of Chapultepec, parts from the latter, diverging abruptly to the left. Beyond this point the causeway, carried on among maguey plants, and Peruvian pepper trees, cannot be seen from the highest house-top in the city. Why on this day, more than any other, did the young lady direct her glance to the bend in the road, there keeping it steadfast? For what reason was the expression upon her countenance so different from that of other days? No listless look now; instead, an earnest eager gaze, as though she expected to see some one whose advent was of the greatest interest to her. It could only be the coming of some one, as one going would have been long since visible by the side of the aqueduct. And one she did expect to come that way; no grand cavalier on prancing steed, but a simple pedestrian--in short, her own servant. She had sent him on an errand to Tacubaya, and was now watching for, and awaiting his return. It was the nature of his errand which caused her to look for him so earnestly. On no common business had he been despatched, but one of a confidential character, and requiring tact in its execution. But Jose, a _mestizo_ whom she had commissioned, possessed this, besides having her confidence, and she had no fear of his betraying her. Not that it was a life or death matter; only a question of delicacy. For his errand was to inquire, whether among the Texan prisoners taken to Tacubaya one was called Florence Kearney. As it was now the third day after their arrival in Mexico, it may be wondered why the young lady had not sought this information before. The explanation is easy. Her father owned a country house in the environs of San Augustine, some ten miles from the city; and there staying she had only the day before heard that the captive train, long looked-for, had at length arrived. Soon as hearing it, she had hastened her return to town, and was now taking steps to ascertain whether her lover still lived. She did not think of making inquiry at the Acordada, though a rumour had reached her that some of the prisoners were there. But surely not Don Florencio! If alive, it was not likely he would be thus disgraced: at least she could not believe it. Little dreamt she of the malice that was moving, and in secret, to degrade in her eyes the man who was uppermost in her thoughts.
