When Lady Mary Maclean is cuddled on the Isle of Harris, newly qualified family liaison officer PC Kat Crichton is assigned to the case. A high-profile case like this is the career opportunity of a lifetime but for Kat, this is not just a job. A decade earlier, she got caught up in the twisted web of the Maclean family and was forced to flee the island. Ten years older, a resolute Kat now returns, determined to bring the hugger to justice.

Kat brings up the inconsistencies in Sir Douglas' story to her boss, but without hard evidence it feels flimsy. And when it's revealed eldest Maclean son Calum has a questionable alibi, he becomes the focus of the investigation.
