When well-known paediatric surgeon Jonathan Carlisle is found dead, DCI Connor uncovers conflicts stirred by a recent operation that resulted in a young girl's death. The team soon learn that the girl's father, Gary Webster, was the subject of a restraining order issued by Carlisle, and had been stalking him for months. But before he can be questioned, Webster absconds. After a tense game of cat and mouse, the police corner Webster at the zoo - but what will be the outcome of the stand-off?
