The Poison Tree by Erin Kelly is a brilliantly crafted psychological thriller that stands out for its clever plotting and exceptional character studies. Having read it again, (my first reading was way back in 2010), since delving into the equally gripping sequel, A House of Mirrors, my appreciation for this book has only deepened. Having been a much loved book, from what was to become one of my favourite authors, the only real surprise was discovering quite how much the world has changed since the opening in 2007 where wired headphones and congestion zones are the latest thing!

The narrative is meticulously woven, keeping readers on edge as secrets and lies gradually unravel. Kelly's ability to maintain suspense throughout is nothing short of masterful, ensuring that each twist and turn feels both unexpected and inevitable.

The characters in The Poison Tree are richly developed and deeply compelling. Karen, though understated in demeanour, holds a prominent position in the story. Her quiet strength and introspective nature provide a stark contrast to the charismatic and magnetic Biba, making their dynamic both fascinating and complex.

Rex is another standout character, nervously overshadowed by the bolshie Guy yet possessing a hidden depth that adds layers to the story. His character's evolution and the subtle hints of his true nature make him intriguingly enigmatic.

Kelly's exploration of these characters' relationships and the intensity of their interactions adds a profound emotional depth to the novel. The interplay between them is a masterclass in character development, making The Poison Tree a gripping and thought-provoking read.

Overall, Erin Kelly's skilful storytelling and nuanced character portrayals make The Poison Tree an unforgettable novel. It's a book that not only thrills but also prompts readers to reflect on the complexities of human nature and relationships
