A Cold Heart

With shaking hands, she tells herself she can do this. There’s nothing she won’t do for her daughter. But will she ever forgive herself for what happens next?

When a woman is brutally snatched from her home in broad daylight, DS Malkie McCulloch must race against time to find her before it's too late. The victim is a carer, mother and wife living a quiet life in rural Scotland. But someone wanted to hurt her badly enough to risk everything.

As Malkie pieces together the scattered clues she left behind, the case takes a devastating turn. What started as a simple shoplifting incident has spiralled into something far more dangerous, connecting to the violent death of a local security guard and a web of secrets that threatens to destroy everyone it touches.

With his personal life in turmoil – a newly discovered relative, a deepening relationship with fellow trauma survivor Deborah, and the haunting reopening of his mother's suspicious death – Malkie fights to stay focused on finding the victim alive. As winter temperatures plummet, his investigation reveals a story of family betrayal and desperate love that shows just how far a parent will go to protect their child…

The fourth book in a gripping Scottish crime thriller series featuring DS Malkie McCulloch, a brilliantly complex detective who will risk everything to protect the innocent. Perfect for fans of Angela Marsons, JM Dalgliesh and JD Kirk.
