"That is very true. If in my knowledge of THE secret I do what I can to spare an innocent girl (especially, remembering your own reference to her when you told my story to the assembled guests at Chesney Wold) from the taint of my impending shame, I act upon a resolution I have taken. Nothing in the world, and no one in the world, could shake it or could move me." This she says with great deliberation and distinctness and with no more outward passion than himself. As for him, he methodically discusses his matter of business as if she were any insensible instrument used in business.

"Really? Then you see, Lady Dedlock," he returns, "you are not to be trusted. You have put the case in a perfectly plain way, and according to the literal fact; and that being the case, you are not to be trusted."

"Perhaps you may remember that I expressed some anxiety on this same point when we spoke at night at Chesney Wold?"

"Yes," says Mr. Tulkinghorn, coolly getting up and standing on the hearth. "Yes. I recollect, Lady Dedlock, that you certainly referred to the girl, but that was before we came to our arrangement, and both the letter and the spirit of our arrangement altogether precluded any action on your part founded upon my discovery. There can be no doubt about that. As to sparing the girl, of what importance or value is she? Spare! Lady Dedlock, here is a family name compromised. One might have supposed that the course was straight on--over everything, neither to the right nor to the left, regardless of all considerations in the way, sparing nothing, treading everything under foot."

She has been looking at the table. She lifts up her eyes and looks at him. There is a stern expression on her face and a part of her lower lip is compressed under her teeth. "This woman understands me," Mr. Tulkinghorn thinks as she lets her glance fall again. "SHE cannot be spared. Why should she spare others?"

For a little while they are silent. Lady Dedlock has eaten no dinner, but has twice or thrice poured out water with a steady hand and drunk it. She rises from table, takes a lounging-chair, and reclines in it, shading her face. There is nothing in her manner to express weakness or excite compassion. It is thoughtful, gloomy, concentrated. "This woman," thinks Mr. Tulkinghorn, standing on the hearth, again a dark object closing up her view, "is a study."

He studies her at his leisure, not speaking for a time. She too studies something at her leisure. She is not the first to speak, appearing indeed so unlikely to be so, though he stood there until midnight, that even he is driven upon breaking silence.

"Lady Dedlock, the most disagreeable part of this business interview remains, but it is business. Our agreement is broken. A lady of your sense and strength of character will be prepared for my now declaring it void and taking my own course."

"I am quite prepared."

Mr. Tulkinghorn inclines his head. "That is all I have to trouble you with, Lady Dedlock."

She stops him as he is moving out of the room by asking, "This is the notice I was to receive? I wish not to misapprehend you."
