"I shall be gone only one night," he said.

"I have often been a night alone."

"I know," he said; "but somehow it's worse leaving you with so much money in the house."

"No one knows it will be there."

"That is true, except that every one knows I have been collecting large sums."

"They will think you have gone to pay it in as usual."

"Yes," he said with an effort.

"If I tell him to-night," she thought, "it will make him still more anxious about leaving me. Perhaps he would refuse to go, and he must go. I will not tell him till he comes back."
