“You have no—” Julia began angrily.

“I am Miss Dean,” ignoring Julia, Marjorie serenely continued. “Will you please tell me who you are?”

“Yours truly, Jane Everest, Marjorie.” A little laugh rippled out from behind the concealing mask.

“Oh, Jane!” There was inexpressible relief in the exclamation. “I’m so glad it’s you. Are you the soph who is to blow the unmasking whistle? If you are, don’t blow it for at least ten minutes yet.”

“I insist that Miss Everest shall blow it, and at once,” burst forth Julia Peyton furiously. “She has just promised me that she will.”

“No, I haven’t promised to blow the whistle at once, Julia,” Jane steadily corrected.

“What right have you to interfere in our fun? Post graduates are not supposed to interest themselves too closely in class affairs.” Julia tossed her head in withering disdain of Marjorie. “What right have you to prevent me from exposing that detestable Miss Cairns. Do you consider it honorable or fair to the traditions of Hamilton to permit a former student who was expelled to come on the campus socially?”

“How do you know, Miss Peyton, that Miss Cairns, a former student of Hamilton, is present in the gymnasium, or has been here this evening?” Marjorie inquired with a cool evenness that made Julia gasp. “Have you seen her?”

“I know, and so do you. Didn’t she trip us with her umbrella? Didn’t we hear her voice. I recognized it. You may not have.” The answer was freighted with sarcasm.

“A masker carrying an umbrella tripped us. When she spoke her voice sounded like that of Miss Cairns,” Marjorie stated impersonally. “I did not see the masker’s face. Did you?”
