Final answer:
The question appears to involve a mix-up of different literary works, as neither Brom Bones nor Braddock Washington is associated with a plot to kill Sophie. Brom is from 'The Legend of Sleepy Hollow' and Braddock is from 'The Diamond as Big as the Ritz'.
Step-by-step explanation:
The question appears to be about a plot element from a work of fiction; however, there is a mistake as 'Brone' seems to be a typographical error and no clear context is given regarding who Sophie is.
The characters mentioned in the references provided are Brom Bones from Washington Irving's 'The Legend of Sleepy Hollow' and characters from F. Scott Fitzgerald's short story 'The Diamond as Big as the Ritz', namely Braddock Washington and his daughter Kismine. Neither of these references includes a character named Sophie or a plot involving someone being brought into the forest to be killed. Instead, Brom Bones is known for riding his horse Daredevil and Braddock Washington expresses disapproval over his daughter Kismine potentially being romantically involved.
