Who does author, Timothy Tyson, interview in the opening pages of the book, The Blood of Emmett Till?

The Blood of Emmett Till by Timothy B. Tyson begins with the author interviewing Carolyn Bryant, now 80 years old and still in hiding after many years. She gives him a transcript of the trial and her unpublished memoir that purportedly tells the truth about what happened on that August day in 1955 when Emmett Till entered her husband’s small grocery store and had some sort of encounter with her.
