“Yes, but she is a good sort, or I am mistaken. She and her brother are the only children of an iron-master somewhere up Northumberland way. He got engaged to her when traveling last winter, and she came down to be introduced to his people, with her brother as escort.

But to-day must be a day of inquiries.”
“My practice—” I began.
“Oh, if you find your own cases more interesting than mine—” said Holmes, with some asperity.
