The Last Remains by Elly Griffiths

Forensic archaeologist Ruth Galloway's life is at a crossroads when she learns that the board of the University of North Norfolk is proposing the closing of the Archaeology department, of which she is the head. Ruth wonders what she will do if the plans come to fruition. Ruth is also consulting on a case of some human bones that have been found in the wall of a building in King's Lynn. DCI Harry Nelson, the father of Ruth's daughter Kate, is leading the investigation. It turns out that Cathbad, a friend of both Ruth's and Nelson's, had known the person whose bones were found. Suspicion and worry soon follow when Cathbad disappears. Could he have information about the murder? In this latest book in the Ruth Galloway series, author Griffiths advances the story of Ruth, Nelson, and their circle satisfyingly as the series is being put to rest for now.
