In the Blink of an Eye

DCS Kat Frank is a police detective who trusts her instincts. She is also a widowed single mother, and she knows what loss does to people. In the UK, someone is reported missing every 90 seconds, and her work is to find those who have vanished.

Kat is chosen to lead a pilot programme that teams her with AIDE Lock, an Artificially Intelligent Detective Entity. Together they review two missing person cold cases. Her gut feeling meets his logic, and neither approach is easy to set aside.

Then both cold cases become active again. Lives are at risk, and the pair have to find a way to work together before another missing person becomes one more statistic. When the investigation turns personal for Kat, Lock is the only one in a position to help her.

This is a crime novel and a police procedural built around an unusual detective duo, one human and one machine. The central contrast is AI against human experience, logic against instinct, and the book uses it to ask what being human means. Expect a mystery with real urgency, where the partnership matters as much as the search itself.
