More than a hundred research interviews were conducted for the television series The Killing Season. For this book we have drawn on 144 hours of interviews and transcripts of fifty-five on-camera interviews, as well as three recorded research interviews. The majority of the material in this book is new and does not appear in the ABC series.
Transcripts prepared for television are literal, including every breath, noise and stumble. For the book we have followed the editing style used in television: repetitions, ums and ahs and breaths have been removed from the text. Ellipses indicate that we have joined answers from the same section of the interview, as well as where longer quotations have been edited.
