"P'r'aps she could be cleared out."

"Miss Conyngham is frightfully stuffy about changing dorms after she and Matron have worked it all out."

Joey got out of bed, shouldered into a dressing-gown, thrust on slippers, and seized her blue quilt.

"As it's rather difficult to go to sleep, while you're making all this row, I'll sleep somewhere else to-night, if you don't mind," she explained, with elaborate politeness, and was out of the door, trailing her quilt after her, before any of the three had recovered from the blank surprise caused by her remark.

When she came out of Bathroom 8, Joey had noticed a ladder at the far end of the passage; she guessed that it must lead on to the roof. And what better place could one find to sleep on than a roof, on such a fine September night as this? Even if it rained she thought the leads would be better than a Blue Dorm full of hateful girls who talked at her.

She scrambled up the latter, stumbling over the blue quilt; pushed open a trap-door, and arrived, sure enough, upon the leads, all silver in the moonlight.

She had been boiling over with fury when she escaped from the Blue Dorm, but this wonderful silver world had a calming effect. It was far clearer now than it had been when she came. Then a haze had hovered over the horizon; now the broad line of the Fossdyke Wash glittered a silver glory on the edge of the white world.

The great stretch of the Walpole Fen intersected by its wide ditches unrolled itself before her, and in the flatness that curious round tower stood out conspicuously. Joey looked at it with interest; it was curious to see a tower standing all by itself like that. She wondered whether she would be allowed to go and explore it sometime, by herself of course, without the company of any of those hateful Redlands girls. And then she thought how interested Mums would be in hearing of it. And then she thought how much more interested Mums would be if she, Joey, had seen the redoubtable blue light which Gabrielle had mentioned. And then she wondered if she would see it to-night, where she would have an even better view than if she had been allowed a window bed. That was the last clear thought in her mind before she found a sheltered corner, rolled herself tightly in her quilt, and fell asleep with her face buried in the hollow of her arm to get away from the moonlight. She dreamt of the tower, of course, but all her dreams were confused, not clear.

She awoke at last to a sense of cold, which had been with her for some time before it roused her.
