Dr Harry Kent. Former Army medic, hospital registrar, police surgeon, drug addict and defender of anyone the world would rather brush aside. His critics say he has a weakness for lost causes.
Usually his police work means minor injuries and mental health assessments. But Solomon Idris's case is different. Solomon Idris has taken eight people hostage in a chicken takeaway, and is demanding a lawyer and a BBC reporter.
Harry is sent in to treat the clearly ill teenager...before the siege goes horribly wrong. When Solomon's life is put in danger again from the safety of a critical care ward, it becomes clear he knows something people will kill to protect. Determined to uncover the secret that drove the boy to such desperate action, Harry soon realises that someone in the medical world, someone he may even know, has broken the doctors' commandment 'do no harm' many times over.
And now only he stands in the way of them causing further hurt...
