‘I devoured this in one sitting’ Rob Rinder, as featured on BBC 2’s Between the Covers

‘Terrifyingly timely and provocative' Val McDermid

'The most original crime novel you'll read this year' Clare Mackintosh 

In the UK, someone is reported missing every 90 seconds.
Just gone. Vanished. In the blink of an eye. 

DCS Kat Frank knows all about loss. A widowed single mother, Kat is a cop who trusts her instincts. Picked to lead a pilot programme that has her paired with AIDE (Artificially Intelligent Detective Entity) Lock, Kat's instincts come up against Lock's logic. But when the two missing person's cold cases they are reviewing suddenly become active, Lock is the only one who can help Kat when the case gets personal. 

AI versus human experience. 

Logic versus instinct.

With lives on the line can the pair work together before someone else becomes another statistic? 

In the Blink of an Eye is a dazzling debut from an exciting new voice and asks us what we think it means to be human. 

'Just brilliant!' Lisa Jewell 

'This has to be a strong contender for crime debut of the year - sharp, perceptive writing and a brilliant new take on the detective duo' T. M. Logan

'Everything you could hope for in a thriller: heartbreaking, intelligent, deftly plotted and so original' Fiona Cummins

'Jo Callaghan makes her entry into the crowded police procedural genre with a fresh take on the buddy-buddy cop trope . . . Provocative and compelling' Vaseem Khan 

‘Brilliant book, total page-turner’ Cerys Matthews, as featured on BBC 2’s Between the Covers

‘I loved it’ Angela Scanlon, as featured on BBC 2’s Between the Covers 

‘One of the most original crime fiction partnerships I have ever read. In The Blink of An Eye explores the potential future of technology with an in-depth, unforgettable look at grief and humanity, and how surprisingly, one can aide the other. A breathtaking debut that will have you eagerly awaiting the next instalment in what is set to be a beloved series’ Jack Jordan

'Fresh, innovative and very, very clever. Flawlessly paced, plotted and researched, it's laugh out loud, heart-achingly sad and doesn't have a dull moment. I raced through it. Simply sensational' M. W. Craven 

‘I started reading this morning and ten hours later I’ve finished it! It’s so, SO good – really properly compelling, impossible to put down – I was desperate for the solution to the mystery – but so human and moving and massively thought-provoking on what makes us human’ Laura Marshall

'The kind of fresh and fearless debut I just adore. Wildly original, heartfelt, funny, and properly thrilling. Take a bow, Jo Callaghan' Chris Whitaker
