"I have no secrets from Robert," said the widow.
"Oh, well, just as you please; I don't care to have him interfere in what doesn't concern him."
"Any business with my mother does concern me," said Bob; "but I will try not to give you any trouble."
"The business is about that interest," Wolverton began, abruptly.
"What interest?"
"You must know what I mean—the interest on the mortgage."
"My husband paid it on the day of his death."
"It's easy enough to say that," sneered Wolverton, "but saying it isn't proving it, as you must have the good sense to know."
"When my husband left me on that fatal morning, he told me that he was going to your office to pay the interest. I know he had the money and with him, for he had laid down the wallet, and I saw the roll of bills."
"Why didn't he pay it, then? That's what I'd like to know."
