"We shall know to-morrow," said Olive as they entered the school door.

But in less than five minutes after the words had escaped her lips, part of the truth had come to light, and it happened in this way.

Lily (who was under the impression that her neat little scheme for aiding her memory had been quite unobserved by any one except Maggie, who had benefited by it, too), already, in imagination, saw her own name at the head of the list. But she thought it would be just as well to make assurance doubly sure, by securing Monica's downfall, if it were possible, in case she should be perilously near. So, as she passed up to the desk with her paper, taking care to be the last girl who filed out, she very quietly dropped her little paper of tables, etc., on the floor of Monica's desk, in such a manner as to make it appear as if it had slipped off Monica's lap, when she rose to go out.

"Now we shall be quits!" was her amiable thought, as she went with the rest into the playground. She bound Maggie, with promises of many good things, to absolute secrecy, and returned to the classroom to await developments.

The girls had no sooner taken their places than they became aware that something was wrong! The head-mistress Miss Buckingham came in with a very stern expression on her face, and Miss Churchill seemed on the verge of tears.

"I am grieved to tell you that there is a cheat--yes, a cheat," and Miss Buckingham repeated the words with scornful emphasis, "amongst you girls of the Fourth Form. Miss Churchill found this paper, containing arithmetical tables and various other information, under one of the desks when you had left the classroom. I desire that girl, who has sought to secure a good place in the examination list by such despicable means to stand up in her place."

A furtive glance from Lily, who was as white as a ghost, revealed the fact that the head-mistress was looking straight at Monica, and the real culprit breathed freely, and the colour came back to her cheeks. She did not know that Olive's gaze was riveted on her, or she would not have felt so easy in her mind as she did!

"Come, stand up," repeated Miss Buckingham, and Monica began to feel uncomfortable. Why did the head-mistress look so persistently at her, when it was Lily Howell who was the culprit.

"Well, I am sorry she will not confess it herself," said the calm, cold voice of the head of the school; "but Monica Beauchamp is the cheat!"

"I'm not!"
