The Last Camel Died at Noon (Amelia Peabody #6)

It's true: the last camel is gone, leaving Amelia, Emerson and Ramses to bake under the desert sun in the winter of 1897. Armed with a mysterious note and map, they have been commissioned to locate a lost English aristocrat and his wife, who disappeared over a decade ago. In this tribute to H. Rider Haggard (King Solomon's Mines), the family marches into the desert where survival depends on solving a mystery as old as Ancient Egypt, and where they meet a young girl, Nefret, who will join their family and change their lives forever.
