Lucie parted from Kurt as his friend, and as she slowly walked back to the castle she reflected upon the perils encompassing the people who had become so dear to her. She pondered how to put the Freiherr upon his guard without betraying Celia's secret, and how at the same time to influence the old man to relinquish his foolish prejudice against Kurt. She could hardly warn him directly, but could it not be done indirectly through Werner, perhaps? If she should inform the Finanzrath that his connection with Repuin and other French agents was no longer a secret, that his movements were watched, that he was in danger of arrest, and that his presence in Castle Hohenwald imperilled the safety of his father and brother,--if she begged him to leave the castle, would he not comply with her advice? Celia hastened to meet her friend; she had not been able to remain within-doors. Arrived at the castle, the girl threw Pluto's bridle to old John and hurried to her room to change her dress, thinking that she would await Anna in their sitting-room; but, although the windows there were all wide open, the confinement seemed to stifle her; she wanted air,--not the air of park or garden, but that of the cool, fragrant forest. As she issued from the gate of the court-yard and was just about to turn into the broad forest road she encountered Arno, and was hurrying past him, longing to see Anna and hear what she had said to Kurt, when he detained her, saying sternly, "Where are you going?" "That is not your affair," she pertly answered her brother's harsh question. "I might as well ask you, Where have you been?" "I have been in the forest." "And I am going to the forest." She would have passed him, but he still detained her. "Do you usually select this road for your afternoon ride?" Celia blushed. What did he mean by the question? Did Arno know anything of her meetings with Kurt? With feminine evasion she hastily rejoined, "Why should I always choose this tiresome broad road?" "Why, indeed? How long since you returned from your ride?" "About a quarter of an hour ago," she answered, frankly. "And did you ride on the broad road to-day?" "What a foolish question! Let me go, Arno! How can it possibly interest you when or whore I ride?" But Arno still held her hand fast, seeming not to notice her embarrassment. He gazed darkly down the forest road. If Celia pursued it she would meet Kurt and Anna together. Such a discovery would be but a merited punishment for Anna, but what impression would it produce upon his innocent sister? A second glance along the road reassured him,--Anna was slowly approaching the castle alone. He let go Celia's hand, relieved of an ugly dread lest Anna should have confided to her pupil her love-affair with Poseneck. That Celia knew nothing about it was clear from her replies to him; the "will-o'-the-wisp" was so frank a creature.
