Theodosia is back and so is Mr. Tetley of the British Museum, but he is not at all the same as when she last crossed paths with him. To add to the chaos, mummies from museums all over London mysteriously appear at her father's museum and no one knows how they got there or why. Another mysterious adventure filled with lots of mummies, curses, secret societies, and now, governesses. The first book in the series is Theodosia and the Serpents of Chaos followed by Theodosia and the Staff of Osiris and continued with Theodosia and the Eyes of Horus.
