“This way,” answered Molly, looking indeed like a sleepwalker as she glided down the hall to the main steps.

If the girls had glanced back they would have noticed a figure creep softly after them.

“But the gate is locked,” objected Nance.

“I know, but we’ll find another way. Come on.”

Down the steps they hastened noiselessly. At the bottom, instead of going straight ahead, Molly turned to the left and led the way to a sitting room for visitors on the ground floor of the tower. The windows of the Tower Room, as it was known, looked out on the campus. They were small, deep-silled, and closed with iron-bound wooden shutters like the doors into the cloisters. Mounting a bench, Molly opened the inside glass casement of one of the windows and drew back the bolt which secured the shutter. Then she hoisted herself onto the sill, crawled through the window, and holding by both hands dropped to the ground. Nance, of a more practical temperament, wondered how they would ever get back into the Tower Room; but blind, unquestioning faith is an infinitely stronger staff to lean upon than uneasy speculation, as Nance was one day to find out.

“When the night watchman makes his rounds, will he see the window open in the tower?” she thought. “And if he does, what will he do? Give the alarm at once or try to find out our names and report us? If he reports us, what then? We may be expelled, or suspended or punished in some awful way.”

So Nance’s thoughts busily shaped out these tragic events as she followed Molly out of the window and dropped to the gravel walk below. The tower clock struck twelve while the two girls flitted across the campus. It was a strange adventure, Nance pondered, and one she would never have undertaken, or even considered, alone. But then her instincts were not like Molly’s. The inner voice which spoke to her sometimes was usually the sharp, reproving voice of a Puritan conscience. It spoke to her now, but she turned a deaf ear to it for once.

It told her how absurd she would appear to other people in this dangerous midnight escapade; what risks she was running. Judy, of course, had spent the night with one of the other girls, it said. It troubled her mind with whispers of doubts and fears; it ridiculed and abused her, but not once did it weaken her determination to follow Molly wherever she intended to go. And presently, when Molly quickened her footsteps into a run, Nance kept right at her elbow like a noonday shadow, foreshortened and broadened.

Molly turned in the direction of the lake. Nance’s heart gave a violent thump. She had believed all along that they were taking a short cut across to the gymnasium, instead of following the gravel walk.

“Molly, you don’t think——” she began breathlessly.
