The Janus Stone (Ruth Galloway Mysteries, Bk. 2)

Forensic archaeologist Dr. Ruth Galloway is called in to advise when builders, demolishing a Victorian house in Norwich, uncover the skeleton of a child - minus the skull. Is it some ritual sacrifice or just plain murder?

The house was once a children's home. DCI Harry Nelson meets the priest who used to run it, who tells him two children did go missing forty years before - a boy and a girl. They were never found.

But someone is trying hard to put both Ruth and Nelson off the scent - and a seemingly forgotten crime becomes terrifyingly real, with deadly consequences.
