Professor Patricia Wiltshire takes you on a journey through the fascinating edgeland where nature and crime are intertwined. She takes you on a journey searching for bodies of loved ones - through woodlands, along hedgerows, field-edges, and through plantations - solving time since death, and disposal of remains, from ditches to living rooms. She gives you glimpses of her own history: her loves, her losses, and the narrow, little valley in Wales where she first woke up to the wonders of the natural world. Pat shows you how her work with a microscope reveals tell-tale traces of the world around us, and how these have taken suspects of the darkest of criminal activities to court.
