The fourth beguiling Dr Ruth Galloway mystery. It is Halloween in King's Lynn, and forensic archaeologist Dr Ruth Galloway is attending a strange event at the local history museum - the opening of a coffin containing the bones of a medieval bishop. But then Ruth finds the body of the museum's curator lying beside the coffin.

Soon the museum's wealthy owner lies dead in his stables too. These two deaths could be from natural causes but DCI Harry Nelson isn't convinced, and it is only a matter of time before Ruth and Nelson cross paths once more. When threatening letters come to light, events take an even more sinister turn.

But as Ruth's friends become involved, where will her loyalties lie? As her convictions are tested, she and Nelson must discover how Aboriginal skulls, drug smuggling and the Aboriginal ritual of The Dreaming may hold the answer to these deaths - and be the key to their own survival.
