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.
"Hush!" she said. "There's no use in disturbing everybody." Then as the match flared up she saw that it was no Wraith of Vengeance she held. The sheet fell to the floor, revealing Ida Shane, dressed even to hat and furs, and carrying her leather travelling-bag.
"THE president wishes to see the members of the Shadow Club in his office immediately. They will please pass out before we proceed with the opening exercises."
That was the announcement Professor Fowler made in chapel next morning, and a clap of thunder from a clear sky could not have been more unexpected or more startling in its effect. A frightened silence pervaded the room so deep that every girl could hear her heart beat. A message to Doctor Wells's office at that hour was almost unheard of. He always conducted the chapel exercises himself. It must be a matter of grave importance indeed that would cause his absence now, and the sending of such a message.
