The following are some lines from To Kill a Mockingbird:
I maintain that the Ewells started it all, but Jem, who was four years my senior, said it (had started?) started long before that. He said it (had begun?) began the summer Dill (had come?) came to us, when Dill first (had given?) gave us the idea of making Boo Radley come out.
The original words are likely to be: 'Jem, who was four years my senior, said, "It started long before that. It began the summer Dill came to us, when Dill first gave us the idea of making Boo Radley come out." If these were the original words of Jem, then changing them to indirect speech would require a "backshift" in verbs which is not the case in this line. Other examples are:
I said if he wanted to take a broad view of the thing, it really (had begun?) began with Andrew Jackson.
For: I said: "If you want to take a broad view of the thing, it really began with Andrew Jackson."
Mr Conner said they (had cussed?) cussed so loud he was sure every lady in Maycomb (had heard?) heard them.
For: Mr Conner said: "They cussed so loud I am sure every lady in Maycomb heard them."
Miss Stephanie said old Mr Radley (had said?) said no Radley (had been going? It looks odd) was going to any asylum, when it (had been?) was suggested that a season in Tuscaloosa might be helpful to Boo. Boo wasn't crazy, he was high-strung at times. It was alright to shut him up, Mr Radley (had conceded?) conceded, but instead that Boo not be charged with anything: he was not a criminal.
For: Miss Stephanie said: "Old Mr Radley said no Radley was going to any asylum, when it was suggested that a season in Tuscaloosa might be helpful to Boo. (He said) Boo wasn't crazy, he was high-strung at times. It was alright to shut him up, Mr Radley conceded, but instead that Boo not be charged with anything: he was not a criminal."
So why are there no backshifts of verbs? What am I missing?
