Oldenburg laughed. "So do I," he said. "Let us give it up."
It took some time before the excited horses could calm down again. The mysterious man was still riding at full speed, and in a few moments he had disappeared in the lane which led down to the fishermen's village.
Half an hour afterwards they reached the gates of Grenwitz. Oswald got off his horse and gave the reins to the groom, to shake hands with the baron.
"If you were not too much bored," said the latter, "I hope we may repeat the experiment soon again. Good-by!"
Oswald reached his room without having met a soul in the quiet courtyard or in the silent house. As he was leaning out of the open window and looked down into the darkening garden, he saw two persons walking up and down in the avenue, whispering and laughing. They were Albert and Marguerite. They had evidently improved the good opportunity to advance in their conjugation of aimer.
CHAPTER X.
"DEAR SIR! To succeed in all undertakings equally well is not given to any one, not even to the most favored knight. You will therefore, it is hoped, understand why a person, who has watched with much astonishment the process you have made in the favor of a certain lady, is anxious to become personally acquainted with the magic charm you possess, and therefore desires to see you. If you are disposed to afford him this pleasure, you are requested to take a walk this evening, at eleven o'clock, near the smaller Grenwitz gate. Under the old beech-tree on the road to Berkow you will, if you consent, find a carriage to convey you to the place of rendezvous. There you will find everything required to begin a more intimate acquaintance.
"It need hardly be mentioned, that, of course, an affair of so much delicacy has to be treated with the utmost secrecy. The coachman will ask you 'Qui vive,' and if you answer 'Moi,' he will know that you are the right person. Au revoir, monsieur!"
This was the text of a letter which the mail-carrier from the neighboring town handed Oswald on the evening of the next day.
He read the odd note several times before he could recover from his surprise. Who was the "person" who wished to make his personal acquaintance? What "lady" was meant? Had the mystery of the forest chapel fallen into indiscreet hands? Could Baron Cloten be the author of the challenge? The peculiar, cool manner of the young nobleman at their last meeting favored this presumption. Or was the meeting accidental, and the mysterious rider the real writer? Was he, perhaps, one of Cloten's spies? On the other hand, was not the conversation which Baron Barnewitz had had with Oldenburg, and which Oswald had heard as an unwilling listener, sufficient evidence that Cloten had quite enough to do with his own difficulties?
