"Very, indeed. And what does she propose to do with the photograph?"

"To ruin me."

"But how?"

"I am about to be married."

"So I have heard."

"To Clotilde Lotham von Saxe-Meiningen, second daughter of the King of Scandinavia. You may know the strict principles of her family. She is herself the very soul of delicacy. A shadow of a doubt as to my conduct would bring the matter to an end."

"And Irene Adler?"

"Threatens to send them the photograph. And she will do it. I know that she will do it. You do not know her, but she has a soul of steel. She has the face of the most beautiful of women and the mind of the most resolute of men. Rather than I should marry another woman, there are no lengths to which she would not go—none."

"You are sure that she has not sent it yet?"

"I am sure."
