Cairo. December 1917. Following a tip-off from notorious spy Fredrick Fredricks, Fiona Figg and Kitty Lane of British Intelligence find themselves in the hustle and bustle of Egypt. But ancient mummies aren't the only bodies buried in the tombs of Cairo. When a young French archeologist is found dead in a tomb in the desert with his head bashed in, and an undercover British agent goes missing, the threat moves closer to home. As they dig deeper, soon Fiona and Kitty uncover a treasure trove of suspects, including competing excavators, jealous husbands, secret lovers, and belligerent spies! Fiona wonders if the notorious Fredrick Fredricks could be behind the murders? Or is the plot even more sinister? One thing is clear - if Fiona and Kitty can't catch the killer, they might end up sharing a sarcophagus with Nefertiti.
