Recalled to Life — Reginald Hill

It was a crime of passion in one of England's great houses, an open-and-shut case. But thirty years later, when the convicted nanny is freed, then spirited off to America before she can talk, Yorkshire's Superintendent Dalziel returns to the scene of the crime with Inspector Pascoe, determined to dig up the corpus deliciti he investigated a generation before. Did the wrong aristocrat hang? Dalziel and Pascoe find decades-old clues that implicate a member of the royal family. When one of their prime leads is found dead, Dalziel is put 'on leave' - and heads for New York to learn what the nanny knows.
