In The Oracle of the Dog story by G. K. Chesterton, the author was talking about Donald whose killed father was annoyed from his reckless actions, so he transferred his wealth and property to his sister, but after his death, the sister insisted on restoring the property to her brother.
The author saying: "I discovered with some astonishment she really had insisted on restoring the property to poor Donald; so I hope he’s had a healthy shock and will treat it sensibly. There was never much really the matter with him; he was very young and his father was not very wise"
Does"There was never much really the matter with him" mean "he hadn't any problem with transferring the wealth to his sister from the beginning"?
