"I! What do you take me for?"

"But you will, Star; you will have to. There's no other way to keep the thing dark."

"Do you suppose I mean to keep it dark?"

"Star! Star!"

"Do you suppose it for a single moment, Susan?"

Miss Forest's voice was calling to the girls: "Come, girls; no more loitering. We must get back into our wagonettes and drive home or we shall be overtaken by the dusk."

Star and Susan were obliged to postpone any further conversation, but as Susan was getting into the wagonette she turned to her companion.

"We must fight this thing out," Susan said. "Where, and when?"

"In my room to-night," said Star without a moment's hesitation.
