My Thoughts:

Crime fiction with a speculative twist, In the Blink of an Eye is an impressive debut from British author, Jo Callaghan.

DSC Kat Frank, newly returned from bereavement leave, is unhappy when her boss directs her to lead a pilot program to test the suitability of using an AIDE (Artificially Intelligent Detective Entity) in a police investigation. Professor Okonedo, determined to better the operation of the force, asserts that the AIDE is not only capable of collating and analysing vast amounts of data in a fraction of the time required by a human, but has been programmed to filter out the bias and prejudice that can taint investigations. Kat doesn’t believe algorithms can truly account for the vagaries of humankind, or replace the experience and instincts she, like most good police officers, often rely on.

With input from her small handpicked team, consisting of DI Ryan Hassan and DS Debbie Browne, along with AIDE Lock, who presents as a lifelike hologram with the default appearance is as a fairly nondescript 6ft tall white male, and Professor Okonedo as an observer, Kat selects two missing person cold cases for them to review. Unexpectedly the investigation’s into the current whereabouts of university student Tyrone Walters and wanna be actor Will Robinson converge when the team discovers a sinister link in their disappearances.

Essentially In the Blink of an Eye is a police procedural, Kat and her squad conduct interviews, investigate clues and gather evidence to explain the fate of the missing men. Callaghan develops a solid mystery and I thought it played out well. There’s plenty of tension, enhanced by the anonymous perspective of a young man suffering at the hands of shadowy figures, and effective twists in the plot.

The speculative elements of the novel are thought-provoking. The conflict inherent in Kat and Lock’s different approaches to investigation, and how each affects the case, is fascinating, with the strengths and weaknesses of both methods fairly illustrated. Lock’s superior ability to gather and analyse information is undeniable but Kat proves that empathy, discretion, and an understanding of nuance are also valuable investigative tools.

I really enjoyed the unique dynamics of Kat and Lock’s partnership. Kat is a likeable lead character. As a decorated police officer, with 25 years of experience in the force, Kat is a dedicated investigator who has confidence in her abilities, but she is a little emotionally fragile given the recent death of her husband, caused in part by of a misdiagnosis by an AI, which fuels her antagonistic attitude towards the AIDE. Kat is also a mother, with her teenage son on the cusp of relocating to begin university, and as such there are aspects of the cases that she strongly relates to. It’s surprisingly difficult to refrain from ascribing human motivations and emotions to AIDE Lock. Solely driven by statistics and logic, though capable of deep learning that gives it the ability to adjust its behaviours, it nevertheless has a distinct character which I really grew to like.

With its clever, provocative premise and appealing, complex characters, In the Blink of an Eye is a compelling novel, and I believe only the first of what promises to be a great series.
