I thoroughly enjoyed this book even though it was a bit slow to start. I love how it weaved international intrigue throughout a relatively straightforward mystery. Karen Pirie is a great character - smart, assertive, emotionally detached, but entirely lovable.

The story centers on a skeleton found in the roof of a historic building in Scotland and draws in some academics who were involved in the conflicts in the Balkans in the 90s and the ineffective International Criminal Court. The narrative comes together quite slowly as the story is told from two povs - Karen and a professor whose partner went missing 8 years prior. Additionally, there are two lawyers from the international war crimes court on the hunt for an vigilante assassin who has been picking off some of the war criminals who have escaped justice. This was a complex mystery with a satisfying conclusion.
