In the peril of her life, Lady Dedlock is resolved never to yield or droop. She continues to appear, as before, in high society and arranges for Rosa to leave. This latter action surprises and dismays Tulkinghorn, and he tells Lady Dedlock that their agreement is no longer in force. He will not, he says, reveal her secret past to Sir Leicester tonight, but he feels free to inform him at any time after this. Just before ten o'clock the same night, Tulkinghorn is found dead; he has been "shot through the heart."
