Upon reaching the outside, they found old Oliver, with the sleigh drawn up to receive them. Jacquelina looked all around, to see if she could discover Thurston Willcoxen on the grounds; and not seeing him anywhere, she persuaded herself that he must have hastened home. But she saw Dr. Grimshaw, recognized him, and at the same time could but notice the strong resemblance in form and manner that he bore to Thurston Willcoxen, when it was too dark to notice the striking difference in complexion and expression. Dr. Grimshaw approached her, keeping his cloak partially lifted to his face, as if to defend it from the wind, but probably to conceal it. Then the evil spirit entered Jacquelina, and tempted her to sidle cautiously up to the professor, slip her arm through his arm, and whisper: "Thurston! Come! Jump in the sleigh and go home with us. We shall have such a nice time! Old Grim has gone to Leonardtown, and won't be home till to-morrow!" "Has he, minion? By St. Judas! you are discovered now! I have now full evidence of your turpitude. By all the saints! you shall answer for it fearfully," said the professor, between his clenched teeth, as he closed his arm upon Jacquelina's arm and dragged her toward the sleigh. "Ha! ha! ha! Oh! well, I don't care! If I mistook you for Thurston, it is not the first mistake I ever made about you. I mistook you once before for a man!" said Jacko, defiantly. He thrust her into the sleigh already occupied by Mrs. Waugh and Marian, jumped in after her, and took the seat by her side. "Why, I thought that you set out for Leonardtown this afternoon, Dr. Grimshaw!" said Mrs. Waugh, coldly. "You may have jumped to other conclusions equally false and dangerous, madam!" "What do you mean, sir?" "I mean, madam, that in conniving at the perfidy of this unprincipled girl, your niece, you imagined that you were safe. It was an error. You are both discovered!" said the professor, doggedly. Henrietta was almost enraged. "Dr. Grimshaw," she said, "nothing but self-respect prevents me from ordering you from this sleigh!" "I advise you to let self-respect, or any other motive you please, still restrain you, madam. I remain here as the warden of this pretty creature's person, until she is safely secured." "You will at least be kind enough to explain to us the causes of your present words and actions, sir!" said Mrs. Waugh, severely. "Undoubtedly, madam! Having, as I judged, just reasons for doubting the integrity of your niece, and more than suspecting her attachment to Mr. Willcoxen, I was determined to test both. Therefore, instead of going to Leonardtown, to be absent till to-morrow, I came here, posted myself at a favorable point for observation, and took notes. While here, I saw enough to convince me of Jacquelina's indiscretions. Afterward leaving the spot with lacerated feelings I drew near her. She mistook me for her lover, thrust her arm through mine, and said, 'Dear Thurston, come home with me--'"
