Suddenly her hands dropped and one clutched the railing, as the window shutters of the next room were thrown open with a bang and some one stepped out on to the balcony adjoining hers. The intruder was a large and elderly woman in a rustling black dress. The light from the room streaming out behind her showed that she was portly and gray-haired, and the way she peered through the vines, changing quickly from one view-point to another, showed that she was impatient. When she turned, Mary saw that her dress, which was made to fasten in the back, was open from collar to belt, and she readily guessed the trouble. Forgetting that her presence was unknown to the anxious watcher, she leaned forward through the dark, saying politely, "Can I help you, Madam?" If a hand had reached out and grabbed her, the old lady could not have been more startled. With a stifled shriek she backed up against the wall to hide her open bodice, and stood there limp and panting. "Merciful _fathers_! how you scared me!" she breathed as Mary's face appeared in the full light. When she saw only a little school-girl of seventeen or thereabouts her relief found vent in a hysterical giggle. It shook her plump shoulders until they both started to laughing so hard that she could barely find voice to explain, or Mary to apologize. "I just couldn't get my dress hooked up the back," she finally managed to say. "I rang half a dozen times for a chambermaid, but the ones on this floor all seem to be off duty this time of evening, and I won't ask a bell-boy as some of the ladies do. I don't think it's decent. So I just thought I'd look down into the court and see if I couldn't catch sight of James. He did it yesterday and I vowed I'd never ask him again. He's willing enough, but he kept me standing a solid half hour by the clock, and we were both tuckered out when he got through." "Let me come and do it for you," said Mary with her usual alacrity for following up promising beginnings. "Oh, if you only would!" was the grateful answer. "I'll go in and unlock the door--" Before she could finish her sentence Mary had climbed lightly over the railing which divided their balconies, and was following her into her room through the long windows that opened to the floor.
