"Jean!" she called, in a hoarse stage-whisper. "Jean! Did you hear that? What do you suppose it is?"
Jean gave the thread another tweak, and then answered, in the same loud whisper, "It sounds to me as if something was trying to spell your name by tapping. It comes from under your bed, but then of course you don't believe in such things. It may be a warning."
"I wish I dared put my foot out of bed," said Ada, her teeth chattering. "I'd get up and make a light. You do it, Jean. I'd do that much for you if the noise was under your bed."
"Sh!" warned Jean. "I believe something is really calling you. It's certainly spelling your name. Now count. One knock—that is A. One, two, three, four—D. One again—A. Yes, that spelled Ada. Now it's beginning again. One, two, three, four—D. One—A." The knocks followed in rapid succession until Ada, realizing that they were going all the way to Y, was almost paralyzed with terror.
"Oh, Jean!" she wailed. "Stop it! Stop it! Get up and make a light, or call the matron, or something! I can't stand it a minute longer! I'll be a gibbering idiot if you don't stop that awful knocking!"
Jean still continued to jerk the thread, till she heard Ada spring up desperately as if to jump out of bed. Then she said, "Oh, do be still, Ada Day. It's nothing but a spool in a tin box. See! I'll strike a match and show you. I was only playing a trick on you because you boasted nothing could frighten you. Don't rouse the house, for mercy's sake."
It took much time and much pleading on Jean's part to convince Ada that there was really no spirit under her bed, and then it took more time and pleading to appease her anger. The sound of voices and the striking of a match aroused the matron. She lay for a moment, wondering what was the matter; then, thinking that some one might be ill and in need of her services, she got up, slipped on a warm bathrobe and her felt bedroom slippers, and stepped out into the hall to investigate.
All was quiet, but she had a feeling that some mischief was afloat. An inkling of the disturbing element in the school had reached her early in the day, and although she had said nothing to the teachers, she had made a careful round of inspection just before going to bed. Some rumour of the doings of the Shadow Club which had come to her made her go to the west wing and push aside the portière hanging over the door that led to the outside stairway. The bolt was in place, but it slipped easily in its sheath as if it had lately been oiled. Selecting a key on the ring at her belt, she locked the door. "I'll risk a fire for one night," she thought, "but I can't risk some other things."
Although the hall was quiet when she stepped out now in the midnight silence, some feeling that all was not right made her slip on down the front stairs. There was no light, excepting a faint starlight, that served to show where the windows were. As she stood there listening, about to strike a match, something in white brushed down the stairs past her. Half in a spirit of mischief, thinking to pay the girl or ghost, whichever it was, back in her own coin, the matron threw her arms around the sheeted figure.
There was a muffled scream of terror. But, holding her captive fast with one strong hand, the matron struck a match with the other.
