"She ran after you because you were running from her," observed the wise Judy. "People always give advice about ghosts and robbers and mad dogs," said Molly. "And they are the ones that run the fastest when the ghosts and robbers and mad dogs appear." "Do you think it was a ghost?" asked Judy, ignoring the irritation of her friends. "If it had been a ghost it would have caught up with us," answered Molly, while Nance in the same breath said emphatically: "I don't believe in ghosts." Nance and Molly were heroines for several days after this, and during this time the "ghost" did not reappear on the campus, although a close watch was kept for her. The Williams sisters insisted on walking down the avenue every night at half past nine in hopes of seeing a real phantom, but she was careful to keep herself well out of sight during this vigilance. One night some ten days later, just as the town clock tolled midnight, Molly waked suddenly with a draught of cold air in her face. She sat up in bed and glanced sleepily through the open door into the sitting room. "Where did the air come from?" she wondered, and then noticed that Judy's door was open and slipped softly out of bed. Why she did not simply close her own door she never could explain, but some hidden impulse moved her to look into Judy's room. A shaded night lamp turned quite low cast a soft luminous shadow right across Judy's bed, which was empty. Molly started violently. Once before they had come into Judy's room at midnight and found her bed empty. The startling recollection caused Molly to run to the open window. As she leaned out her hand touched something rough--a rope. "A rope ladder!" she whispered to herself, horrified. "Great heavens, Judy has done for herself now." Just then the rope scraped her knuckles and she felt a tug at it from below. "Some one is coming up." Molly looked out. "Judy," she whispered in a tone filled with reproach. "How could you?" The voice from above must have frightened the climber, for, with an excited little gasp, she missed her hold on the rope and fell backward, where she lay for a moment perfectly still. It was not a very great fall, but it must have hurt, and instantly Molly climbed to the window sill and began to make her way slowly down the ladder. It was not so difficult as she had thought, but she was frightened when at last she bounded onto the ground, and she was freezing cold in spite of her knitted slippers and woolen dressing gown. "Have you hurt yourself badly?" she asked, leaning over Judy, who was endeavoring to sit up. "No, only dazed from the fall," whispered Judy. "Go on up, will you, or we'll both get caught." "You'd better go first," said Molly, "I'm afraid to leave you down here alone. Go on, instantly," she added, remembering that she must be stern since Judy richly deserved all the reproaches she could think of.
