An Adam Dalgliesh mystery by an award-winning, internationally acclaimed novelist. Two student nurses lie dead, the great hospital nursing school of Nightingale House is shadowed with terror, and a secret medical world of sex, shame, and scandal is about to be exposed. It is the job of Adam Dalgliesh of Scotland Yard to probe even deeper into the macabre mystery and unmask a killer who operates as skillfully as a surgeon -- before the epidemic of evil gets completely out of hand.
