"She'll get some of Wee Watts' hair. She's got a Jane, and a switch, too--it's about the color of yours--and she'll pin it on your pillow--fix it up so that if Fraulein suspects anything and takes a peek in your room she'll swear you're sleeping like a baby." Blue Bonnet fairly gasped. "Oh, we haven't been here three years for nothing, let me tell you," Annabel confessed. "You need all your wits." "How am I going to wake up?" Blue Bonnet asked. "I know I never can without an alarm of some kind. I'm an awfully good sleeper." "That's easy. Tie a string round your wrist and put the string outside the transom--let it hang down the wall. Nobody will see it after the lights are out. Some of us will pull it and waken you about a quarter to twelve. Don't wake Joy. She might go to Miss North, or do something." "No, she wouldn't. Joy isn't so bad as we all thought, Annabel. I want to tell you about her sometime. We must try to be nicer to her if she stays here." "Oh, she'll stay, never fear. They aren't expelling any graduates--especially a student like Joy Cross. She's made a wonderful record. Miss North's got to admit that, whatever else Joy's done. Good-by. See you later. I'm in an awful hurry. You'll excuse me, won't you?" About five minutes before time for the lights to be put out, there was a gentle knock at Blue Bonnet's door. Sue Hemphill put her head in and glanced round. "Where's Joy?" she asked, drawing something in after her. "In the bathroom." "Good! Here, turn down your bed quick, Blue Bonnet." Blue Bonnet complied, and Sue swiftly deposited a pillow underneath the sheet, leaving only a brown head gracefully exposed to view. Blue Bonnet clapped her hand over her mouth to prevent a shriek. The thing so resembled a human head that it convulsed her for a moment. "Sue! How ever did you do it? Why, from the back it looks just like me. I always braid my hair that way at night. It's wonderful!" "Practice makes perfect. Get in on the other side and don't disturb it. Cover it up a bit more till Joy gets to bed. Don't forget the string on your arm, and, whatever you do, don't get scared and scream when I yank it. Remember! Good night." She was off before Blue Bonnet could say a word, even ask a question. Blue Bonnet got out her night-dress and threw it over the brown head on the pillow, loitering about her undressing. Joy finished her toilet and got into bed quickly. A moment more and the lights were off. Blue Bonnet tied the string to her arm, but she had to wait until Joy fell asleep before she could put it through the transom, and Joy was unusually wakeful. Blue Bonnet heard her tumble and toss upon her bed while she tried to ward off sleep herself. She gave up in despair finally. It would never do to get up on a chair and put the string through with Joy awake. She fell into a doze thinking what she should do, and the next thing she knew she was being shaken rudely while a voice in her ear whispered:
