A routine case turns sinister when Dr Temperance Brennan is accused of mishandling the autopsy of a missing heiress. Someone has made an incriminating accusation that she missed or concealed crucial evidence.
Before Tempe can get to the one man with information, he turns up dead. The heiress isn't the only elderly female to have appeared on Tempe's gurney recently. Back in Montreal, three more women have died, their bodies brutally discarded.
Tempe is convinced there's a link between their deaths and that of the heiress. But what - or who - connects them? Tempe struggles with the clues, but nothing adds up. Has she made grave errors or is some unknown foe sabotaging her? It soon becomes frighteningly clear. It's not simply Tempe's career at risk. Her life is at stake too.
