It was clearly visible to Edwin and to Albert that a mutual passion united the prisoner and Roseline, while every fleeting hour served more and more to endear them to each other. Edwin, already entangled in the toils of hopeless love, and enduring all the pangs of despair and apprehension, trembled for the fate of a sister for whom he felt an uncommon degree of fraternal affection, but to whom he could not prevail on himself to mention a subject so delicate and distressing. The prisoner made no attempt to conceal his ardent love for Roseline:--it was an effort as far beyond his comprehension as his power, and, though, he made no formal declaration, every word, look, and action, betrayed the situation of his heart. Of the world he was totally ignorant; of marriage he had not even thought,--that being a subject on which they had never conversed, and his own situation, desperate and hopeless as it was, now seldom engaged his attention. Roseline, and Roseline alone, engrossed his every idea: while he saw her smile, and heard the sound of her voice, he was contented and happy, and, when she was absent, the wish, of rendering himself more worthy and better able to converse with her, stimulated him to pay unremitting attention to his own improvement, and the instructions he received; but, had he been assured he should see her no more, he would have sunk into the same apathy and indifference for life and its enjoyments from which her kindness had drawn him. After Madeline had left the castle, and before the return of Sir Philip, Edwin, at the utmost risk of discovery, which would have involved him and the object of his regard in danger and difficulties, prevailed upon her to grant him several interviews in the chapel of the nunnery. One night, Albert, having agreed to accompany him through the subterranean passage, the trembling nun met them at their entrance, and seated near the tomb which concealed the door, listened to the vows of her lover.--Equally reluctant to part, they sat longer than usual, and heard footsteps in the chapel. Madelin rightly concluded it was one of the friars come to say mass for the soul of a nun lately dead. When the ceremony was ended he departed, and, as the door closed after him, the resolution of Madeline revived. She knew if they had been discovered, even the life of Edwin would not be secure, and that she should instantly be compelled to take those vows from which there was no release but death.
