Drawing the packet from under her shawl, she handed it to the frowning lawyer, her heart standing still as she saw him turn it over and over in his hand. But his looks if angry were not suspicious, and with a relieved nod she was turning to go when he observed: "I have one word to say to you, Doris. You have told me that you have the welfare of the young ladies you serve at heart. Prove this to be so. If Mr. Huckins comes to the door to-night, or in the early morning, say that Miss Cavanagh is not well and that he had better go to the hotel. Do not admit him; _do not even open the door_, unless Miss Cavanagh or her sister especially command you to do so. He is not a safe friend for them, and I will take the responsibility of whatever you do." Doris, with wide-stretched eyes and panting breath, paused to collect her faculties. A week ago she would have received this intimation regarding anybody Mr. Etheridge might choose to mention, with gratitude and a certain sense of increased importance. But ambition and the sense of being on intimate and secret terms with a man and bachelor who boasted of his thousands, had made a change in her weak and cunning heart, and she was disposed to doubt the lawyer's judgment of what was good for the young ladies and wise for her. But she did not show her doubt to one whom she had secretly wronged so lately; on the contrary she bowed with seeming acquiescence, and saying, "Leave me alone to take good care of my young ladies," drew her shawl more closely about her and quietly slid from the house. A man was standing in the shadow of a great elm on the corner. As she passed, he whispered: "Don't stop, and don't expect to see me to-night. There is some one watching me, I am sure. To-morrow, if I can I will come." She had done a wicked and dangerous thing, and she had not learned the secret. XX. THE DEVIL'S CAULDRON. Frank, being left alone, sat down with the letter Doris had given him. These are the words he read: "DEAR MR. ETHERIDGE: "I must ask you to walk by my house as early as nine o'clock to-morrow morning. If, having read this letter, you still feel ready to meet fate at my side, you will enter and tell me so. But if the horror that has rested upon my life falls with this reading upon yours, then pass by on the other side, and I will understand your verdict and accept it.
