"Yes, it would. Do you suppose I COULD have one?"

"Easy as pie!" declared Jack. "Why don't you?"

"Perhaps I will, after Aunt Adelaide comes. This,—this chaperon to-night is only temporary, you know."

"Yes, I know," said Jack, but he said no more. The discovery of Susan was his secret with Patty, not with Mona. Then the young people prepared to depart, and Patty and Mona stood either side of Mrs. Hastings to assist her, if necessary, in receiving their good-nights.

Jack stood near, too, for he thought he might be of some slight help.

"Good-night, Mrs. Hastings," said Beatrice Sayre. "The girls are coming to my garden party to-morrow, and as my mother also expects guests, I'm sure she'd be glad if you would come."

Susan, much bewildered at being thus addressed, looked about her helplessly, and murmured uncertainly, "Thank you, Miss," when Jack interrupted by saying, "Such a pity, Bee, but Mrs. Hastings goes away to-morrow. Another aunt of Mona's is coming to play chaperon at 'Red Chimneys.'"

"Oh," said Beatrice, carelessly; "then this is good-bye as well as good-night, Mrs. Hastings. I've SO enjoyed meeting you."

These conventional phrases meant nothing on Beatrice's part, but it almost convulsed Patty to hear Susan thus addressed. However, she knew she must play the game a few moments longer, and she did so, watching the thoughtless young guests as they shook hands with the masquerading COOK!

Jack Pennington was the last to go. "I say," he whispered to Patty, "it's been a great success! I don't see how you ever had the nerve to try it, but it worked all right!" Then he went away, and Patty and Mona sank limply into chairs and shook with laughter. Susan instantly returned to her role of servant, and stood before Patty, as if waiting for further orders.
