Kate looked at Elsie, amazed. Such an idea had never entered her head. Her face said so. Again the comrade flashed. But it vanished quicker than before, and this time definitely. “Well, you told your wonderful friends, ‘The boys,’ on me. You do tell, you see.”

Kate had no answer to that.

Elsie whirled about and went to her bed. From under her pillow she took the key, and returning, handed it to Kate, coolly. “Here it is,” she said, “and this is the last time I shall ever ask a favour of you, Kate Marshall. Please don’t use it to-night.”

Kate accepted the key. “All right,” she promised. “I won’t use it to-night. There won’t be time, anyway, with the party and everything.” She was not speaking to the Elsie who had asked the favour, however, but to the vanishing comrade, invisible now, whom she had seen clear enough in that one flash. Was that comrade within hearing, she wondered.

“Thanks,” Elsie said, as though she meant it, and in a relieved tone. Then she straightened. “But just the same, Kate Marshall, I shall never, never, never, never forgive you for calling me a thief, not so long as I live, I sha’n’t.”

“You said you were proud of it,” Kate rather cruelly retorted.

Elsie suddenly threw her arm across her eyes. To Kate’s dismay she was sobbing.

“Don’t cry, don’t cry,” she begged. “The gong rang minutes ago. Quick, wash your eyes. For Aunt Katherine’s sake! She’s been so good to us. Let’s go on pretending everything’s all right.”

Masterfully, but very wretched in her heart because of this bitter weeping of which she was the cause, Kate hurried Elsie into the bathroom, ran some cold water into the bowl, and put a wash cloth into her hands. “Quick, wash your eyes. For Aunt Katherine’s sake!” Kate commanded again, and Elsie obeyed.

Then Kate took her hand and hurried with her out through the twisted passageways to the main front hall and down the stairs. Dinner had been announced some time ago, and Aunt Katherine was waiting, standing and impatient, in the drawing-room. But when she saw them hurrying and hand-in-hand she smiled. When you have dressed for your first real party in your first real party frock you may be expected to be a little late!
