As with most of the Amelia Peabody mysteries I've read, I really had no idea what exactly the mystery was. That said, I loved all of the characters who came back in this one (especially the very poorly written Cyrus Vandergelt--an AMERICAN!), and it was really very suspenseful.

That said, I do wish I had read all of the books in sequence (unfortunately I went by what's in the inside cover, which is alphabetical, not chronological...I think I'm only missing one or two, though), because the solution to the mystery tied back to another book and I was thoroughly lost.
