[Illustration: Sally Placed the Black Box on the Study Table] ------------------------------------------------------------------------ SALLY SCOTT OF THE WAVES CHAPTER ONE UP THE LADDER It was mid-afternoon of a cloudy day in early autumn. Sally Scott glided to the one wide window in her room and pulled down the shade. Then, with movements that somehow suggested deep secrecy, she took an oblong, black box, not unlike an overnight bag, from the closet. After placing this with some care on her study table, she pressed a button, and caught the broad side of the box, that, falling away, revealed a neat row of buttons and switches. Above these was an inch-wide opening where a number of spots shone dimly. After a glance over her shoulder, Sally shook her head, tossing her reddish-brown hair about, fixed her eyes on this strange box and then with her long, slender, nervous fingers threw on a switch, another, and yet another in quick succession. Settling back in her chair, she watched the spots above the switches turn into tiny, gleaming, red lamps that gave off an eerie light. “Red for blood, black for death,” someone had said to her. She shuddered at the thought. From the box came a low, humming sound. She turned a switch. The hum increased. She turned it again and once more the hum rose in intensity. This time, however, it was different. Suddenly the hum was broken by a low, indistinct hut—hut—gr—gr—gr—hut—hut—hut. “Oh!” The girl’s lips parted as a look of surprise and almost of triumph spread over her face. And then, suddenly, she started to leap from her chair. A key had rattled in the door. Before she could decide what she should do, the door swung open and someone snapped on a light. And then a voice said, “Oh! I’m sorry! I’ve been in the bright sunlight. The room seemed completely dark.” “It really doesn’t matter,” Sally spoke slowly, studying the other girl’s face as she did so. The girl was large and tall. Her hair was jet black. She had a round face and dark, friendly eyes. This much Sally learned at a glance. “It doesn’t matter,” she repeated. “I suppose we are to be roommates.” “It looks that way,” the other girl agreed. “I just arrived.” She set her bag on the floor. “I see.” Sally was still thinking her way along. “Then I suppose you don’t know that we are not allowed to have radios in our rooms.” “No—I—” “But you see, I have one,” Sally went on. “I suppose I could be sent home for keeping it, but I’m going to chance it. I—I’ve just got to. It—it’s terribly important that I keep it. It—well, you can see it’s not like other radios. It’s got—” “Red eyes,” the other girl said in a low voice. “Yes, but that’s not all. You couldn’t listen to a program on it if you tried. It—it’s very different. There are only two others like it in all the world.” “I see,” said the new girl.
