Miss Susan Cushing, a secluded lifestyle, received a small bag wrapped in paper — a cardboard box with coarse salt. After pouring out salt, Miss Cushing, in horror, discovered two unpaired human ears, male and female. They are cut off recently. Inspector Lestrade invites Holmes to investigate. Starting by examining the twine, packaging, and address on the box, Holmes begins the investigation.
