The central character of this novel is Karl Jackson. He has survived a brutal upbringing punctuated with savage beatings by his drunken father, and sexual abuse from his uncle Charlie. Karl has a twin, Nathan, but he never faced the same storm of violent rage. Karl Jackson is described in the cover blurb as a sociopath. I am no psychologist, but Jackson’s steady job as a chemistry teacher and his scrupulous and well-planned crimes make me think he is more psychopathic, but it does not matter. He is a genuinely awful human being. His spree of undetected killings started in his childhood when, merely for the fun of it, he pushed a young boy – fishing in the lake where they played – down into the water, and then watched with amusement as the lad struggled, choked, and then bobbed about on the surface as lifeless as the float attached to his fishing line.
Jackson’s genius (hence the title of the book) is to organise killings in such a way that no possible evidence can link the deaths to him. While Jackson was working as a student in Australia, one of his murders involved the ingenious combination of a sleeping bag, a sedative injection and a deadly Brown Snake on a hiking trail in the Blue Mountain region of New South Wales. Jackson exacts an elaborate – and some may say justified – revenge on his father by causing the old man’s death in hospital with a very clever use of cyanide and the sharpened end of a coat hanger.
The background to this novel is the atmospheric landscape of the English Lake District, where Jackson carries out another long delayed act of retribution on his abusive uncle Charlie by faking an accidental climbing death. When Charlie is found dead at the bottom of a solo climb, his head shattered like a melon hit with a hammer, no one believes it is anything other than an unfortunate error of judgement.
Thus far, Jackson has been clever enough to avoid any attention from the police but, inevitably, he meets his nemesis. Theodore “Tex” Deacon is a late career – but distinguished – detective slowly recovering from the trauma caused by the protracted death of his wife. As is the way with institutions these days, he is temporarily sidelined and identified as a vulnerable person in need of psychological help and treatment by the ubiquitous counselling profession. However, his many successes in tracking down murderers brings him to the attention of Debbie Pilkington, an ambitious young reporter with a local Lakeland newspaper. She alerts him to the many coincidences surrounding deaths in the Jackson family, and so he goes off piste to investigate the case.
Black humour is never very far away in this book, despite the body count. Here, Karl Jackson describes the man who is having an affair with his wife.
“Richard Turkington’s graying Beatle cut had a bald spot on top giving him the appearance of a rock star monk. A fleshy roll wobbled over the top of his chinos. Turkington had clearly ignored warning signs of middle age and had lived a pudgy existence preferring a world of pints and puddings. Quite a contrast to the sleek wire framed fell runners surrounded by them at a function like this. Richard looked like Mr Blobby.”
The Genius Killer rattles along at great pace and is sometimes darkly comic, but in Jackson, the author has created a genuine larger-than-life monster. The book ends rather enigmatically, but as it is described as No.1 in the Tex Deacon series, I suspect the Cumbrian copper will be back soon with another case. Mark Robson is a sports journalist and this is his debut novel. It is published by Orla Kelly Publishing and available now.
