“I want a ride, and I want to talk with you,” she said, simply.

As this was precisely what he wanted, he went for the horses without more delay.

Meantime, Gracie, in one of the windows of the bookstore, was supposed to be employed in examining a late book, but in reality gave much attention to the couple who were crossing the street, or rather waiting for an opportunity to do so.

They seemed in no haste, but were conspicuous, even in the crowded street, for their interest in each other. More than one policeman regarded them narrowly, as Professor Ellis stood with head bent toward the lady, engaged in eager and animated conversation. It was just the attitude of absorbed interest with which he had so often listened to Gracie; not on the street, it is true, but in some crowded parlor, and it had flattered her. It made her frown to-day. They were starting now to make the disagreeable crossing. He had taken his companion's hand, preparatory to a leap over a muddy curbing; but Gracie could see that there was a pressure of it that was unnecessary, and, for the street, peculiar; his face, too, was distinctly visible, and the expression on it was what Gracie had seen before, but certainly she supposed no other person had.

Altogether it was probably well for Professor Ellis' peace of mind that he did not turn at that moment, and get a glimpse of the young lady in the bookstore. Instead he took his lady away, and they were lost in the crowd.

Dr. Everett, making all haste with his horses, had still time for anxious thought. Had his experiment been too severe on Gracie? Was it possible that her interest in the man was such that the afternoon's experience had been mixed with pain as well as with disgust? He could not believe it possible that the pure-hearted young girl cared for such a man as Professor Ellis! Yet there had been a look on her face when she saw those two which startled and hurt him.

When fairly seated in his carriage he did not speak until they had threaded the maze of wagons and reached clear ground. Even then he only said, “Now for speed,” and gave the horses their desire, until crowds and business were left behind, and they were driving down a broad avenue, lined on either side with stately yet quiet-looking homes. Then he drew rein, and obliged the horses to walk; he had by this time resolved on probing the wound, if there was one.

“I wish I knew just how much of a villain that man is.” These were the somewhat startling words which broke his silence.

“What man?” Yet the very tones of Gracie's voice indicated that she knew of whom he was speaking.

“That man, Ellis! Professor, I think he is called. I have reason to be very suspicious of him. By the way, Miss Gracie, I think he is an acquaintance of yours. Have you confidence in him?”
