"Unless I butt my head against this plate glass," she exclaimed, "I really don't think I can make it. I can't kick in the glass, for fear of losing my balance."
Suddenly she heard her name called.
"Grace! Grace! Where are you?"
First it was David's voice, and then Anne's, and then the two together, echoing through the empty corridors and classrooms.
"I'm here," she answered. "Help! Help!"
Fortunately, they were passing the door at that instant and heard her muffled cries.
"Here," she cried again, and they saw her at last, clinging desperately to the window ledge.
"I don't dare open the window," exclaimed David, thinking aloud. "The slightest jar might make her lose her balance. Grace," he cried, "I'll have to break out the upper sash. Lower your head as much as possible and close your eyes."
Another instant, and Grace was crouching in a shower of broken glass, which fell harmlessly on her back and the top of her head. David knocked off the jagged pieces at the lower end, and Grace climbed nimbly over the sash.
"There's no time for explanations now," she cried. "I was mysteriously locked in. Has the game been called?"
