For untold years, the perfectly preserved mummy had lain forgotten in the dusty basement of Boston€s Crispin Museum. Dubbed €œMadam X,€ the recently rediscovered mummy is, to all appearances, an ancient Egyptian artifact. But medical examiner Maura Isles discovers a macabre message hidden within the corpse€“horrifying proof that this €œcenturies-old€ relic is instead a modern-day murder victim. When the grisly remains of two other women are found, it becomes clear to Maura and Boston homicide detective Jane Rizzoli that a maniac is at large. Now Maura and Jane must unravel a murderer€s twisted endgame before the Archaeology Killer adds another chilling artifact to his monstrous collection.
