"Are you sure?"
"Yes," said Patty, with ominous emphasis, "I'm sure. He knows," she added, "what will happen if he doesn't."
"What will happen?" asked the Twin.
"Nothing."
The Twin shook her head, and Georgie inquired, "Then why don't you make out his program?"
"I suppose I might as well. I didn't do it before because it sort of seemed like tempting Providence. I didn't want to be the cause of any really serious accident happening to him," she explained a trifle ambiguously as she got out pencil and paper. "What dances can you give me, Lucille? And you, Georgie, have you got the third taken?"
While this business was being settled, a knock unheeded had sounded on the door. It came again.
"What's that?" asked Priscilla. "Did some one knock? Come in."
The door opened, and a maid stood upon the threshold with a yellow envelope in her hand. She peered uncertainly around the darkened room from one face to another. "Miss Patty Wyatt?" she asked.
