The Night I Killed Him by Gill Perdue was published on 10 July 2025 by Penguin Ireland / Sandycove. My thanks to the publisher who sent my copy for review.
I hadn't realised until I had actually finished the book that this is the third in the Shaw & Darmordy series. The author is so skilled at filling in any back story that I had no idea there were previous novels, although I now need to read those too!
Gemma Fitzgerald is an influencer whose online life looks perfect: with a beautiful house, glamorous photos, a doting husband, and a young son, Ferdia. But eighteen years ago, her brother Max disappeared on the night of his 21st birthday. It was believed that he took his own life. Then his body is discoverd washed up on the shore locally and questions begin: was it suicide after all, or has something far more sinister been hidden, for all this time?
Detectives Laura Shaw and Niamh Darmody are called in to unravel what really happened. As the truth is clawed out from the past, Gemma’s own secrets threaten to undo the image she has built so carefully.
One of the greatest strengths in this novel is how the setting feels so perfectly real. DĂșn Laoghaire; the harbour, the yacht clubs, the darkness of hidden secrets, almost becomes almost a character in its own right. It feels as though it's all gloss and glamour on the surface, with darkness hidden deeper - much like Gemma's life really.
I've always been a fan of multiple narratives and the reader follows Gemma, and also the two detectives; Laura and Niamh. This enables the reader to see various aspects of the case from different sides which always adds some depth. Shaw & Darmody are compelling with clear personalities and believable flaws. Gemma’s guilt is tangible and her relationship with young Ferdia makes the reader back her all of the way. And Gemma’s husband is really well created, if diabolical; his behaviour and his manipulations are emotionally distressing but realistic.
The Night I Killed Him is a multi layered, intelligent thriller that asks more than just 'who did it? We think about the lies that we build around ourselves, what happens when those lies start to unravel, and whether redemption is possible when guilt has held you in its grip for nearly two decades.
I couldn’t put it down by the end; I cared about Gemma, I wanted to know what Laura & Niamh discovered, and I ended the book with a mix of emotions. Recommended
