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.

She is asked for help by an old friend whose husband has fallen for a spiritualist; then a plea arrives from an expat colonel whose daughter is threatened by an unknown enemy, and Ramses, now a headstrong teenager, undertakes an adventure that is guaranteed to turn his mother's hair white! Amelia then dreams of a large cat, an Egyptian sign of good luck - which as the situation stands, is in precious short supply...
