El umbral de la mentira

When construction workers carrying out the demolition of an old house in Norwich discover the incomplete skeleton of a child, forensic archaeologist Ruth Galloway tries to clarify its provenance. Is it a ritual sacrifice carried out by our ancestors or a murder victim? Ruth will try to find out with Detective Harry Nelson. The house was an orphanage in the 1970s, and the priest who ran it brings new clues by remembering the disappearance of two siblings, a boy and a girl, whom they never found. Ruth's curiosity grows, and even the discomfort of her pregnancy won't keep her from getting involved in the case. However, she will soon realize that someone is willing to scare her to death.
