No villain is safe in 1903 Egypt as feisty archaeologist Amelia Peabody embarks on her ninth adventure. According to an ancient Egyptian papyrus, dreaming of a large cat means good luck. And that's just what Amelia Peabody could use, as her growing family matures in the new century. What's more, Amelia's dashing husband Emerson has received a mysterious warning not to enter the Valley of the Kings. To Emerson's annoyance, Amelia's meddling distracts her attention as she exposes a fraudulent spiritualist, saves a marriage, and plays matchmaker. But diabolical forces are at work when an unknown tomb reveals a shocking murder -- and the Peabody family dodges bullets from an assassin determined to put an end to their discoveries.
