“Now, who is playing pranks in such a silly fashion, I wonder?” said Hazel crossly, and jumping up, she went into the passage to find out.

Dora Selwyn had two girls in with her; they declared that they had heard nothing—but as they were all talking at once when Hazel went into the room, this was not wonderful.

In the next study Rhoda Fleming was busily writing at the table, while Daisy dozed in a chair on one side of the gas fire, and Joan appeared to be fast asleep on the other side.

These also declared that they had heard nothing; and as the room of the Upper Fifth was empty, and there was no one in the private room of the mistresses, the affair was a bit of a mystery.

Hazel had sharp eyes; she had noticed that Rhoda’s hand was trembling, and that her writing was not clear and decided. She had seen Daisy wink at Joan, and she came to certain conclusions in her own mind—only, as she had no proof, it seemed better to wait and say nothing. So she went back to the study to tell Margaret and Dorothy that evidently some one had come to play a silly prank on them, only had been scared to find that they were all wide awake and at work.

Dorothy stayed awake a good long time that night, thinking matters over, and trying to find out what was the wisest course to take. She was disposed to go to Rhoda and tell her what she had heard, and to say that there was no need for Rhoda to fear her, as there was no danger of her speaking.

When morning came this did not look so easy, and yet it seemed the best thing to do. The trouble was to get the chance of a few quiet words with Rhoda, and the whole day passed without such a thing being possible.

It was two days later before her chance came. But when she tried to start on something which would lead up to the thing she wanted to say, Rhoda swung round with an impatient air, speaking sharply, “You and I do not care so much for each other that we need to hang round in corners gossiping.”

“There is something I wanted to say to you rather badly,” said Dorothy, laying fast hold of her courage, and looking straight at the other.

Rhoda flinched. “Well, whatever it is, I don’t want to hear it—so there you are.” She yawned widely, then asked, with a sudden change of tone, if Dorothy’s head was better, or if it was still sore.
