I love true crime but I have never really read any true crime novels so this was out of my comfort zone. The premise of this case really intrigued me and it wasn't a case I'd heard of before so I was very interested to read about Graham's childhood, crimes and everything that happened in his life. It was so interesting to read about his obsession with poisons from such an early age and the blasé way he administered it to everyone in his life. I liked the extracts from statements, diaries etc really added to the narrative. The sheaf of images included in the middle of the book also added another layer of depth to the experience, seeing pictures of Graham as he grew up and important places in his life at various points as he grew up. With the inclusion of the end notes I will be spending some time locating some of these sources and reading them so I can get a broader and deeper view of the case as this book has piqued my interest for it.
