But Stuart had heard more than enough to whet his curiosity. Indeed, owing to the tenor of those observations,—of which he had been an involuntary listener,—he considered himself entitled to sift the matter to the utmost. Examining the partition, which consisted only of lath and plaster, he discovered, near the ceiling, a small hole in the stucco cornice which surrounded the top of the wall.

"Stratagems are fair in war," thought he, as he mounted upon a side table and placed his eye to the orifice, through which he obtained a complete survey of the next apartment. A lustre hung from the roof, and its light revealed Alvarado and Don Carlos Avallo,—a young cavalier, about three-and-twenty years of age, whom he remembered to have met at Aranjuez and other places. Alvarado, who was intreating him to lower his voice, was standing half undrest,—at least without his vest, doublet, and girdle, as if he had been preparing for rest when disturbed by the visit of Avallo, who appeared to have entered by the window, which stood half open. A short but graceful Spanish mantle enveloped the left side of this young cavalier, who wore his broad hat pulled over his face; but his fierce dark eyes flashed and gleamed brightly beneath its shade, like those of a tiger in the dark; and when at times the rays of light fell on his swarthy cheek, it seemed inflamed with rage, while his teeth were clenched, and his lips pale and quivering. He kept his left hand free from the folds of his velvet mantle, but his fingers grasped tremblingly the hilt of a poniard, which appeared with a brace of pistols in his embroidered girdle. A gold crucifix glittered on his breast, and a long black feather, fastened in the band of his hat, floated gracefully over his left shoulder. He appeared a striking and romantic figure as he stood confronting Alvarado, with his proud head drawn back and his right foot placed forward, while he surveyed the proprietor of the mansion with eyes keen and fiery, and with rage and unutterable scorn bristling on every hair of his smart moustaches.

"Look you, Alvarado," said he, after a very long pause; "I will not be trifled with! Santos! my dagger is likely to punch an unhappy hole in the old friendship we have so often vowed to each other over our cups at Salamanca, if we come not to some terms this very night. Beard o' the Pope, señor! I am not now the simple student I was then. Alvarado! you know me. This night, then—"

"There is but one hour of it to run," observed the other in a deprecating tone. "There is but one hour—"

"Time enough, and to spare, then, thou base juggler!"

"What would you have, insolent?" said Alvarado fiercely, as he closed the casement with violence. "To-morrow I will meet you in the pass of Lanz, and there, with pistols, with sword, or with dagger, I will yield you that satisfaction for which you have such a craving."

The other laughed scornfully. "No, no, my blustering guerilla! such a meeting will not suit my purpose. Every drop of blood in the veins of your body would not wash away the insult you are likely to cast upon the name of Avallo by means of this poor sister of mine. Hear me, Don Alvarado! and hear me for the last time! I tell you that my sister has been wronged,—basely wronged and betrayed by you! I want not your blood; but do my sister justice, or, by the bones of Rodrigo! I will make all Spain ring with the tidings of Avallo's vengeance!"

"How!" said the other sullenly; "do her justice?"

"Wed her,—ay, before this week is out!"

"A week is a short time, Señor Carlos; and you forget that Ximena is likely to live for many months yet," said the other with a grim smile. "Marry Elvira? Fool! the cursed trammels of one unhappy marriage are wound around me already."
