"But if you keep coming with such demands as this I shall soon have nothing to divide with you," said Mrs. Vance. "Aye, but the rich man will soon supply you with more gold," said the harpy, cunningly, as she turned to take leave. "It will be a good while before I get any more money from Mr. Lawrence, so you need not be in a hurry to return for it," said the widow, letting her unwelcome visitor out of the door, and shaking her fist after her departing form. As soon as her heavy footsteps ceased lumbering on the stairs, she hurriedly changed her house-dress for a walking costume of plain material and simple make. She then put on a small, black hat, tied over her face a thick, dark veil, and descended the steps, letting herself quietly out at the front door. Once in the street, she paused and glanced hurriedly up and down. No one was in sight but the crooked form of the old lace-vender going slowly along a few blocks ahead of her. Mrs. Vance set out to follow the old woman, walking briskly a few squares until she came within half a block of her. She then slackened her pace and went on more slowly, keeping herself invisible, but never losing sight of her prey. "I will track the beast to its lair," she said to herself, "and then we will have our reckoning out." Mrs. Vance hurried on at a steady pace, keeping her enemy fairly in sight, but aiming to keep too far in the background to be recognized herself. She had a long walk ahead of her, but she did not mind it, for her excitement was so great that she was insensible to bodily fatigue. She was filled with a raging anger against Ada Lawrence, whose pure, true instincts had so clearly fathomed her meanness and littleness of spirit. Added to this was her hatred of old Haidee Leveret, mixed with an abject fear of the old woman's power against her in the possession of her guilty secret. As she turned corner after corner, and traversed street after street, her mind was busy revolving vague schemes by which to rid herself of the greedy and dangerous old creature who began to hang upon her shoulders heavily as a veritable Sinbad. At length she began to see that she was coming out upon the outskirts of the city. Old Haidee, a little ahead of her, kept on at a swinging pace, hastening her footsteps as she found herself nearing home. Mrs. Vance kept on steadily too, feeling determined to find out the old woman's home if she had any. At last they reached the gloomy old stone house, with its high, forbidding stone wall. Even Mrs. Vance, courageous as she felt herself to be, was conscious of a pang resembling fear as she contemplated the place. But when Haidee was entering the gate she felt a firm touch on her shoulder, and turned to meet the smiling gaze of the beautiful widow. "You see I have overtaken you," was her smooth salutation. "You have followed me!" exclaimed Haidee, with a savage scowl of rage and surprise commingled. "Yes," said Mrs. Vance coolly.
