Monday Mourning by Kathy Reichs (Temperance Brennan #7)

Three skeletons are found in a Montreal basement. The building is old, and the homicide detective in charge dismisses the remains as historic. Not his case. Not his concern. Forensic anthropologist Dr Temperance Brennan is not so sure. Something about the bones of these three young women suggests a different murder. Soon she finds herself drawn ever deeper into a web of evil from which there may be no escape. Three women have disappeared, never to return. Will Tempe be next?
