Forensic anthropologist Ruth Galloway is asked to look at some human bones that were discovered in old chalk mining tunnels below Norwich. Although at first glance she believes they may be medieval, they also show signs of having been boiled. Tests show them to be more modern, perhaps 10 years old or less.
Around the same time, a homeless man named Eddie visits DCI Harry Nelson because he is worried about his friend Babs, who has not been around for two weeks. As the team asks around for Babs, Judy talks to another homeless man named Bilbo, who says Babs may have gone underground. Within a day Eddie is found stabbed to death in front of the police station and Bilbo has disappeared.
The team’s attention is taken away from these events by the disappearance of Sam Foster-Jones, a suburban housewife who vanished from her home after someone came to the door, leaving her four small children alone. Nelson has a feeling that this disappearance is related to that of Babs and the deaths of Eddie and Bilbo.
This series, always entertaining, has improved steadily, especially in regard to the difficulty of guessing the solution. Ruth remains a likable character, and I still enjoy all the secondary characters in the series.
