The Musgraves have "opened their home" to these patients, but it is a grim, cheerless place. Sexton the doctor assisting Watson is stabbed by an unknown person; and the clock in the tower strikes thirteen, an event local legends say precedes the death of a Musgrave.

Holmes returns with Watson to Musgrave Manor, and his immediate impression is one of foreboding: "Houses, like people, have definite personalities and this place is positively ghoulish!"
