Having worshiped Jo Callaghan In the flickering of an eye (Revised here) and Do not leave a trace (Revised here) I was out of me with emotion when a copy of his last book, Human remainsHe arrived at the surprise book mail. My great thanks to the probable suspects for sending me a copy. It is a pleasure to share my review of Human remains today.
Posted by Simon and Schuster on April 24, 2025, Human remains It is available for purchase through the editor’s links here.
Human remains
DCS Kat Frank and Ayed Lock are back in a new avant -garde thriller.
The truth will always come out, but at what cost?
Just arrived from successfully closing its first live case, the future police unit is called to investigate when a headless body is located and without a hand in a Warwickshire farm. But while they work to identify the victim and their murderer, the discovery of a second body begins to cause fears that Aston Strangler has returned. And as bets increase for the equipment, so do the tensions that are prepared within it.
When DCS Kat Frank is accused of putting the wrong man behind bars so many years ago, Aide Lock, the world’s first detective, pursues the truth about what happened with a relentless logic. But Kat is determined to keep the past buried, and when she becomes the objective of a gloomy figure seeking revenge, the blockade is divided between her evidence -based algorithms and her partner’s judgment, with explosive results.
When everything hangs in balance, everything will be reduced to how much an AI machine can learn and what happens when they do. . .
My review of human remains
DCS DCS Kat Frank has a new case to resolve.
Oh dear. I absolutely adored the first two books, In the flickering of an eye and Do not leave a trace, In the DCS Kat Frank and Aide Lock series, so it is supposed to check the third, Human remainsWithout repeating I have no idea, except to say that I think this third book is even better than the first two. I would also say that there is no need to have read the previous books to enjoy Human remainsBut not doing so is to miss a fantastic series.
I loved all aspects of this exciting, skilled and exciting thriller. Normally I am not a great admirer of the police procedure narratives, but Human remains It transcends the usual genre in the most magnificent reading when weaving in scientific and technological elements in a completely natural, and totally convincing way. The terminology is included for the reader to feel educated. However, terminology never prevents the flow of narrative. As a result, it is difficult to emphasize too much how brilliant, how intelligent and how convincing is the story.
To some extent, research on the headless body that is at the beginning of history is just a fraction of interest. The developing relationships within Kat’s team and family, the way Lock continues to evolve, Kat’s past and the scientific development of AI are aspects in layers, fascinating and exciting. What Jo Callaghan does so hypnotically is to take technology and science and overlap these aspects with humanity and emotion in a way that leaves the reader staggering. It is impossible to explain why and how this happens without revealing too much of the plot for others, but it may be sure that this is a plot with moments that hit the heart and deep emotions. It is really fabulous.
And the title is simply wonderful. Human remains It conforms to all aspects of the narrative, from the literal human remains found in the first pages of history, to the aspects of us remaining when reason, logic and rationality are eliminated. As a result, Human remains To entertain completely, but at the same time suggests the future potential for AI, and all humanity, so that the reader believes that they have formed an immutable opinion, Jo Callaghan moves away the certainty and leaves his readers confused, restless and desperate for more.
The issues of history illustrate the power of social networks, the potential and threat of AI, pain and loyalty, with practical surveillance and other aspects that explore the emotional and human connection so that Human remains It is multiple and sensitive resonant.
In case I am not clear (and I am aware of some vagueness here for fear of spoilers), I thought Human remains It was fantastic. I can’t recommend it enough and I am really desperate for more than Kat and Lock. Bright and bright things. Jo Callaghan is an obligatory author!
