Mr. Benjamin looked at him, and shook his head. "Come, dad, I know what you are thinking of," he said. "It's the expense, ain't it?"

"It is, Benjamin," his father groaned. "I hate parting with hard-earned money for exorbitant bills and these long journeys. Couldn't it be done without it, Ben?" he inquired, in a wheedling tone. "There's piles of money gone already in expenses. Piles and piles."

"And if there is, ain't it Miss Thurwell's, you old stupid?" remarked Mr. Benjamin. "'Tain't likely that we should find the money ourselves."

"Of course, of course. But, Benjamin, my son, the money is thrown away for all that. We could charge it, you know—charge it always. We must have a margin—we must positively have a margin to work with."

"Dad, dad, what an old sinner you are!" exclaimed his hopeful son, leaning back in his chair and laughing. "A margin to work with. Ha! ha! ha!"

Mr. Levy looked uncertain whether to regard his son's merriment as a compliment, or to resent it. Eventually, the former appeared to him the wisest course, and he smiled feebly.

"Dad, just you leave this matter with me," Mr. Benjamin said at last. "I know what I'm doing, and unless I'm very much mistaken, I see my way to make this a bigger thing, even as regards the cash, than you and I ever dreamed of. Leave it to me. Hullo! who's that?"

He peered up over the office blind, and sat down again at once. In a moment his cigar was behind the grate, and his expression completely changed.

"Ah! Miss Thurwell, dad," he said coolly, "and I'll bet ten to one I know what she wants. Mind you leave it all to me. I've no time to explain, but you'll spoil it if you interfere. Come in. Why, Miss Thurwell, we were this moment talking of you," he continued, springing to his feet and offering her a chair. "Please come in."

Helen advanced into the room, and lifted her veil. One swift glance into her flushed face confirmed Mr. Benjamin's idea as to the reason of her visit, and he commenced talking rapidly.
