For a moment there was silence. Then Cora asked:
"Who does he say took it?"
"That's just it," went on her brother. "He doesn't say."
"Does he know?"
"He declares he does."
"Then why won't he tell?"
"You can search me. I don't know. He hasn't even told the police, I understand. He merely made that remark to Walter, and I heard about it."
"Oh, Jack, are you sure that's all there is to it?" asked his sister.
"Sure. I'd tell you more if I knew."
At first they thought he was teasing, and the girls, with, all the wiles of which they were capable, besought him to explain, but he could not, and, finally, they accepted his word as final.
