A tiny puncture mark on her wrist was the only sign of the fatal injection that had killed her.

It is Egypt, 2000 BC, where death gives meaning to life. At the foot of a cliff lies the broken, twisted body of Nofret, concubine to a Ka-priest. Young, beautiful and venomous, most agree that she deserved to die like a snake. Yet Renisenb, the priest’s daughter, believes that the woman’s death was not fate, but murder. Increasingly, she becomes convinced that the source of evil lurks within her own father’s household.
