Police surgeon Harry Kent is determined to help those the world would rather brush aside, in a smart and electrifying new crime series that evokes the often-hidden medical world of the London Metropolitan Police.

Dr. Harry Kent likes to keep himself busy—juggling hospital duties with his work as a police surgeon for the London Metropolitan Police—anything to ward off the memories of his time as an army medic.

Usually the police work means minor injuries and mental health assessments. But teenager Solomon Idris’s case is different. Idris has taken eight people hostage in a fast-food restaurant, and is demanding to see 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 at 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 realizes that someone in the medical world, someone he may even know, has broken the doctors’ commandment to “do no harm” many times over . . .
