Critics Review

‘Jo Callaghan amazes again! With the breakneck pace of an action thriller and the emotional weight of a deeply human drama, Body of Lies delivers a hugely satisfying finale to a bold, moving and unforgettable series. A perfect farewell - Kat & Lock forever (sob!)’ Caz Frear, bestselling author of Sweet Little Lies and Five Bad Deeds

‘I loved Body of Lies so much. It was SO compelling and tense but also full of heart and really moving’ Laura Marshall, author of Kiss, Marry, Kill

‘A brilliantly satisfying way to end such an incredible series. Body Of Lies is another fantastic book - Jo has delivered a tense and pacy thriller combined with emotionally relatable characters who I have grown to love and was so sad to say goodbye to, as well as giving us a glimpse into the future and all that AI might bring. Thought-provoking and unsettling - bravo, Jo - I loved it’ Nikki Smith, author of The Guests

‘A murdered MP and a looming cyber attack propel this tense, tech-driven thriller. As DCS Kat Frank teams up with her partner - who just so happens to be the world’s first AI detective - the book smartly probes trust, truth and the uneasy future of policing’ I News

‘The fourth book in Jo Callaghan’s series about DCS Kat Frank and her AI assistant, Lock, is the best yet – and that’s saying a lot …The hunt for evidence of the terrorists’ identity is exciting in itself and Callaghan increases the tension with moving personal stories of those at risk. She also raises disturbing and fascinating questions about the possibilities and dangers of AI … This is a hugely entertaining novel that deals with the most important of modern dilemmas’ Literary Review
