Convinced that the tomb of the little-known king Tutankhamon lies somewhere in the Valley of the Kings, eminent Egyptologist Radcliffe Emerson and his intrepid wife, Amelia Peabody, seem to have hit a wall.

But Emerson's trickery has backfired, and his insistent interest in the site has made his rivals all the more determined to keep the Emerson clan away.
