At that identical moment Miss Beverley opened the door, and, candle in hand, looked round the room to see that all was left tidy. Her inspection was swift; she said "Good night, girls!" shut the door, and went downstairs to drink cocoa in Miss Todd's study. After her evening round the silence rule was a point of honour in the dormitories. Loveday and Diana turned over and went to sleep. Some time in the middle of the night Diana woke with a start, just in time to see Loveday in a blue dressing-gown, with their bedroom candle in her hand, disappearing through the door. Where could Loveday be going? Had she heard burglars? Was she ill? Why had she not roused her room-mate? Could she by any chance be walking in her sleep? All these questions raced through Diana's brain, and, as the quickest way to solve them, she jumped up, fumbled in the dark for her bedroom slippers and dressing-gown, and hurried after Loveday. She could see by the glimmer of light that the candle was going downstairs. She followed, flopping along in her woollen slippers, for she had not had time to draw them on properly. She nearly lost one on the landing, and had to stop. When she reached the hall the light had gone into the seniors' room. Diana walked softly, and peeped cautiously in. She had rather an idea of saying "Boo!" suddenly, and giving Loveday a scare, but she wanted to reconnoitre first. Her friend's back was turned towards her; she was bending over a desk, not her own desk, but Hilary's. She quickly drew out a roll of manuscript, tore it across and across, carried it to the fire-place, put it inside the grate, and applied the candle. Diana, standing in the dark outside the doorway, watched her in utter amazement. So many questions began to rush into her mind that the hall did not seem the best place to answer them. She fled upstairs again, jumped into bed, and lay thinking. In a minute or two Loveday came quietly back, blew out the candle at the door, and, treading softly, also went to bed. Diana did not speak, or betray by any movement that she was awake. It was an hour, however, before sleep came to her. She was on the early practising list, so she went downstairs next morning before her room-mate was stirring. Breakfast passed over as usual; the post-bag came in; Miss Todd sorted and distributed the contents, and the girls retired to read their letters. At ten minutes to nine something happened. Hilary, with wide open eyes and flushed cheeks, came running along the hall. "Somebody's gone and taken my essay out of my desk!" she declared excitedly. Her fellow-seniors wrenched their thoughts from home news. "Impossible!" said Geraldine. "You've misplaced it!" said Stuart. "No, I haven't! I know just where I put it yesterday." "Go and look again!" "I've turned the whole desk out, I tell you, and it simply isn't there!" "Where is it, then?" "That's what I want to know!" "Has anyone taken it for a joke?" "I expect so, but I'll reckon with whoever has!"
