, now available in paperback, is a gripping standalone novel about a cold case that links back to the Balkan Wars of the 1990s. In the center of historic Edinburgh, builders are preparing to demolish a disused Victorian Gothic building. They are understandably surprised to find skeletal remains hidden in a high pinnacle that hasn’t been touched by maintenance for years. But who do the bones belong to, and how did they get there? Could the eccentric British pastime of free climbing the outside of buildings play a role? Enter cold case detective Karen Pirie, who gets to work trying to establish the corpse’s identity. And when it turns out that the bones may be from as far away as former Yugoslavia, Karen will need to dig deeper than she ever imagined into the tragic history of the Balkans: to war crimes and their consequences, and ultimately to the notion of what justice is and who serves it.
