Isabel was suddenly filled with an overmastering desire to break her prison walls and to walk free under the open sky. Apart from its bitter associations she would have lacked courage to visit the pool and the cascade in the dead of night; for the narrow path thither wound in and out of somber thickets. But the broad way, broad enough for a carriage, which ran down from the guest-house to the abbey, and thence, through the avenue of camellias, to the principal gate had no terrors for a soul almost untroubled by superstitious fears. It seemed to the half-stifled, heart-sick Isabel that if she could escape from the house unheard by Jackson and Mrs. Baxter she might find life and healing in those ampler spaces. She did not admit to herself that the broad path and, especially, the paved space in front of the abbey attracted her because they were rich in unembittered memories of hours with Antonio. Room, more room; air, more air: she thought she wanted nothing besides. Having dressed herself swiftly in her lightest garments she threw over her hair a black lace mantilla which she had bought in Oporto, thrust her shoes and stockings into her little bag and crept barefoot to the door. It creaked a little when she closed it behind her; but the steady sequence of sounds which continued to come from the bedroom of Mrs. Baxter proved that the Excellent Creature had heard nothing. Isabel turned away with a shrug of distaste, and descended the stairs. There was no need to listen for the snoring of Jackson, who could have gone on sleeping restfully if she had clattered about the corridor in clogs. The two bolts of the front door were not very hard to draw back, and the latch was easily lifted. On the top step, where she had talked thrice with Antonio, Isabel drew on her stockings and shoes. Then she closed the door behind her, latched it softly, and stole on tiptoe out of earshot down the path. It was not much cooler in the open than in her chamber. Still, she was glad that she had exchanged her narrow cell for freedom. Besides, the far-stretching woods and the vast heavens were more in scale with her immeasurable sorrow. She walked on quickly, eager to hasten away from her hateful prison. The path was cheerful because it led down to the open lowlands and the refreshing sea. Midnight, to Isabel's mind, usually held no more terrors than noonday. But when a vague shape confronted her under a tree she started violently. Some gossip of Joanninha's awoke in her memory--some ridiculous village story about a ghostly monk who haunted the domain on dark nights. Advancing boldly upon it she found that the vague shape was only a dead trunk clothed in creepers. She tried to laugh; but the laugh would not come, and suddenly she knew what was meant by fear.
