It's a story that began in a rickety old home on a cold June morning in 1994 where five members of a seemingly ordinary New Zealand family were gunned down. There were two suspects. One lay dead from a single bullet to the head. The other was the only survivor: David Bain. Since then the country has asked: Who killed the Bain family? David or his father Robin? And why? Award-winning journalist Martin van Beynen has covered the Bain story closely for decades. Now his book brings the story completely up to date: exploring the case from start to finish picking through evidence old and new plumbing the mysteries and motives interviewing never-before-spoken-to witnesses and guiding readers through the complex police investigation and court cases seeking to finally answer the question: Who was the killer?
