None of these deductions is particularly germane to the story: they are merely Holmesian logical exercises. When the visitor, Mr. Grant Munro (whose name Holmes observed from his hatband) returns, Holmes and Watson hear the story of Munro's deception by his wife Effie. She had been previously married in America, but her husband and child had died of yellow fever, whereupon she returned to England and met and married Munro. Their marriage had been blissful—"We have not had a difference, not one, in thought, or word, or deed," says Grant Munro—until she asked for a hundred pounds and begged him not to ask why. Two months later, Effie Munro was caught conducting secret liaisons with the occupants of a cottage near the Munro house in Norbury. Grant Munro has seen a mysterious yellow-faced person in this cottage. Overcome with jealousy, he breaks in and finds the place empty. However, the room where he saw the mysterious figure is very comfortable and well furnished, with a portrait of his wife on the mantelpiece.
