Just finished "The Golden One", by Elizabeth Peters, the 14th book in the "Amelia Peabody" series. This is a book of two halves (or rather, of two quarters, and a half
); the first and last quarter of the book are the type of "Egyptological mystery" that were the mainstay of most of the earlier books in the series, while the central half of the book is a spy story, with Ramses Emerson travelling to Gaza in Palestine on behalf of British Intelligence to find out whether or not the stories about his uncle Sethos having become a Turkish agent have any truth to them. Very good indeed, but this really is a series you need to read in order - don't jump in at this book!
