Hippopotamus Pool - Elizabeth Peters - Bog

When a
masked stranger offers to reveal an Egyptian queen's lost tomb
to Amelia and Emerson in 1900, they are intrigued to say the
least. But the guide mysteriously disappears, leaving them to
sail to Thebes to follow his trail. The fact that Ramses and
Nefret are along on the journey both helps and hampers efforts
to solve this mystery. Soon all four are risking their lives as
they foil kidnappers, grave robbers and ancient curses. And
intrepid Amelia finds herself faced with a surprising new
villain who is every bit as clever and resourceful as she is!
