"But there is. You act _so_ strange."

"I--I don't feel very good."

"Then you did run too hard, after all."

"It wasn't that, Nan." Bert looked around him. "Do you see anything of
Danny Rugg?"

"No." Nan stopped short. "Bert Bobbsey, did you have a fight with him?"

"No--that is, not a real fight. I chased him with some snowballs and he
threw a big chunk of ice at me."

"Did he hit you?"

"No, he--he--oh, Nan, perhaps I had better tell you. But you must
promise not to tell anybody else."

"Tell me what?"

"Will you promise not to tell?"

"Yes," said Nan promptly, for she and her twin brother always trusted
each other.

"When Danny threw the ice at me it flew past and broke Mr. Ringley's
window."
