This is the latest from Caro Ramsay in a favourite Scottish crime series, featuring DCI Christine Caplan, her life more settled as she lives in a caravan with husband, former architect Aklen, who seems to be recovering in the beauty of the more rural surroundings, whilst the building works continue on their dilapidated cottage. Caplan is surprised when a former police colleague she had not kept in touch with, Rachel Ghillies, a dying cancer patient in a hospice, married to former senior officer, Rory, asks her and Lizzie Fergusson to visit her on her deathbed. A barely coherent Rachel, clearly in a lot of pain, asks them to look into a cold case she had been investigating below the radar, the names are not familiar and barely make sense, but what is clear, Rachel does not want them to let Rory know.
Caplan finds herself at a murder-suicide, Roderick Taylor and Peter Todd at their home, but something about the scene does not feel quite right. This is followed with her making her way to Glen Douglas and MOD territory, where there is the nightmare sight of a horrifyingly badly beaten body of a young male, unrecognisable, with a missing tooth. It is going to take some work to identify him as no such person has been reported missing. Why? An anxious and fearful father, photographs his daughter, Bethany, on her way to volunteer, but she never returns home, abducted it would seem from a park. Rory, using his influence, contacts Caplan, persuading her to mount a hunt for her. Could there possibly be any connection between what happens to Bethany, and the missing cold case victims, identified by Rachel?
Caplan is supported by her small, determined, and hardworking police team, but the workload generated by the cases is overwhelming, and despite what help Sarah Linden gives, she is being starved of resources, are there powers keen to see her not succeed? However, nothing is going to put her off, in what is the most complex and gruesomely horrendous of cold cases with numerous victims, and the urgent need to locate a Bethany who is thought to be in grave danger. This is a brilliant addition to Ramsay's moreish crime series. I cannot wait for the next book! Highly recommended to fans of Scottish crime and other readers new to the author. Many thanks to the publisher for an ARC.
