Harriet has been reading Crocodile on the Sandbank, the first of Elizabeth Peters' Amelia Peabody mysteries. She loved it and had to have volume two, The Curse of the Pharaohs, ready to go as soon as she reached the last page of volume one.
These books about a Victorian Egyptologist were originally recommended to me by a very well-read friend who said they were tremendous fun. Harriet agrees and is very glad to know that there are many more in the series for her to enjoy. I rather fancy them, too.
Have you read them?
Edited to add: Reading all your comments, it looks as though these books are a real treat in store!
