On quitting his mansion and entering the street, the dense weight of the atmosphere became more and more apparent. The heat was so oppressive that the streets were actually deserted--even the artisans had closed their stores; darkness had fallen suddenly, shrouding the beautiful twilight peculiar to Spain as with a pall. Morales unconsciously glanced towards the west, where, scarcely half-an-hour before, the sun had sunk gloriously to rest; and there all was not black. Resting on the edge of the hill, was a far-spreading crimson cloud, not the rosy glow of sunset, but the color of blood. So remarkable was its appearance, that Don Ferdinand paused in involuntary awe. The blackness closed gradually round it; but much decreased, and still decreasing in size, it floated onwards--preserving its blood-red hue, in appalling contrast with the murky sky. Slowly Morales turned in the direction of the castle, glancing up at times, and unable to suppress a thrill of supernatural horror, as he observed this remarkable appearance floating just before him wherever he turned. Denser and denser became the atmosphere, and blacker the sky, till he could not see a single yard before him; thunder growled in the distance, and a few vivid flashes of lightning momentarily illumined the gloom, but still the cloud remained. Its course became swifter; but it decreased in size, floating onwards, till, to Morales' strained gaze, it appeared to remain stationary over one particularly lonely part of the road, known by the name of the Calle Soledad, which he was compelled to pass; becoming smaller and smaller, till, as he reached the spot, it faded into utter darkness, and all around was black. That same evening, about an hour before sunset, Arthur Stanley, overpowered by the heat, and exhausted with some fatiguing military duties, hastily unbuckled his sword, flung it carelessly from him, and, drinking off a large goblet of wine, which, as usual, stood ready for him on his table, threw himself on his couch, and sunk into a slumber so profound that he scarcely seemed to breathe. How he had passed the interval which had elapsed since his interview with Marie and her husband, he scarcely knew himself. His military duties were performed mechanically, a mission for the king to Toledo successfully accomplished; but he himself was conscious only of one engrossing thought, which no cooling and gentler temper had yet come to subdue. It was a relief to acquit Marie of intentional falsehood--a relief to have some imaginary object on which to vent bitterness and anger; and headstrong and violent without control or guide, when his passions were concerned, he encouraged every angry feeling against Morales, caring neither to define nor subdue them, till the longing to meet him in deadly combat, and the how to do so, became the sole and dangerous occupation of heart and mind.
