Meet Anton Perchek - "The Doctor" - master of torture and the most terrifying physician since Hannibal Lecter.
With his estranged wife, Evie, scheduled for surgery the next day, Dr Harry Corbett goes to visit her for what he hopes will be a quiet evening of reconciliation. But when he reaches Evie's hospital room he finds her dead. The police suspect murder. And Corbett is their only suspect.
Harry is unprepared for the stunning revelations that follow. His beautiful, ambitious wife was leading a double life, and had uncovered some dangerous secrets that were enough for someone to kill her. Then the killer strikes again, and once more, Harry is the only suspect.
Corbett realises that the killer, medically sophisticated, coolly arrogant, moving undetected through a busy urban hospital, can only be a doctor. And he wonders - how many more victims will receive his lethal silent treatment?
