DCI Karen Pirie is a copper in the historic cases unit, based out of Edinburgh. As she battles to close a 30 year old string of rapes, her friend and forensic anthropologist, River Wild calls her to the site of a newly discovered bog body and she battles with a spy in her unit placed by her new boss. A multi-layered story with a beautiful slow burn and with twists and turns that take us across the UK, Europe and world as well as all the way back to WWII. It’s a beautiful addition to the series from the unrivalled queen of tartan noir.
