chunk: Holmes considers the solution so simple that he asks Lestrade not to mention his name in connection with it. A few simple questions to Miss Cushing, a few observations, a cable to Liverpool, and a visit to Miss Cushing's sister Sarah (Holmes was denied admittance by the doctor because she was having a "brain fever") convince Holmes that the ears belong to Miss Cushing's other sister, Mary, and her extramarital lover, and that they have been murdered. He is convinced that Mary's estranged husband, Jim Browner, is the murderer, and that Browner had sent the cardboard box containing the ears to the Cushings' house in Croydon (addressing it merely to "S. Cushing"), not realizing that Sarah was no longer resident there. Browner, who is an unpleasant man when drunk, had meant to horrify Sarah (rather than Susan) because he ultimately blamed Sarah for causing the trouble that culminated in his murder of his wife and her lover.
