The Mummy and Miss Nitocris

George Griffith is very little known now, but in the late 19th and first few years of the 20th centuries, he was a writer of science fiction/fantasy and a utopian socialist a la H G Wells. This was apparently one of his minor works, where an Egyptologist and his daughter discover that they are the reincarnations of, respectively, a high priest and Queen in ancient Egypt. Other characters they meet in a series of dramatic events are also reincarnations of ancient Egyptians. This is a mixture of science, fantasy, high politics and Ruritania style manoeuvrings, and is quite fun, though it does drag in places, and the ending seemed quite sudden.
