One morning, early in December, Miss Teddington, who was distributing the contents of the postbag, handed Stephanie a small parcel. It was only a few days after the latter's birthday, and, supposing it to be a belated present, the mistress did not ask the usual questions by which she regulated her pupils' correspondence. The letters were always given out immediately after breakfast, and the girls took them upstairs to read in their dormitories during the quarter of an hour in which they made their beds and tidied their rooms. This morning, just as Ulyth was shaking her pillow, Rona came in, chuckling to herself. The Cuckoo's eyes twinkled like stars. "D'you want some sport?" she asked. "If you do, come with me, and have the time of your life!" Ulyth put down the pillow, and hesitated. Fifteen minutes was not too long an allowance for all she was expected to do in her room. But Rona's manner was inviting. She wanted to see what the fun was. The temptress held the door open, and beckoned beguilingly. "All serene!" yielded Ulyth. Rona seized her by the arm and dragged her delightedly down the passage. "Now you're chummy," she murmured. "Whatever you do, though, don't make a noise and give the show away!" Still in the dark as to the Cuckoo's intentions, Ulyth allowed herself to be led to Dormitory 2, No. 4, at the opposite side of the house. We have mentioned before that the bedrooms at The Woodlands were very spacious--so large, indeed, that each was partitioned into four cubicles divided by lath-and-plaster walls. A passage inside the dormitory gave access to the cubicles, which were in fact separate little bedrooms, except that the partition walls, for purposes of ventilation, did not reach the ceiling. At present the fourth cubicle in Dormitory 2 was unoccupied, but its furniture was rather curiously arranged. One of the beds had been pulled close against the partition, and a chest of drawers, with the drawers removed, had been placed upon it. "I fixed it up last night, and it was a job," whispered the Cuckoo. "Good thing I'm strong. Now we've got to climb on that, and you'll see what you'll see!" Ulyth had an uneasy consciousness that she ought not to be mixed up in such a business; but, after all, the girls often scrambled up and peeped into one another's cubicles for a joke, so her action would not be without precedent. She was a very human person, and liked fun as well as anybody. With extreme caution she and Rona mounted the chest of drawers, trying not to make the slightest noise. Their eyes were just on a level with the top of the partition, and they had a good view of the next cubicle. The occupants, Stephanie and her room-mate, Beth Broadway, were far too absorbed to think of looking up towards the ceiling. Their attention was concentrated on the parcel which had arrived by the post. It contained a small bottle, carefully packed in shavings, and also a typewritten letter, the purport of which seemed to electrify Stephanie.
