This is also the last known address of explorer Willoughby Forth and his young wife, who disappeared fourteen years before the events of the novel, and have been presumed dead. Willoughby's nephew Reggie was keen to renew the search for the missing couple -- he even has a rough map, sketched on a page from one of Emerson's own notebooks -- but does he have reasons other than familial ties for wanting to know the truth behind their disappearance?
Add to this a great deal of interesting speculation about what ancient Egyptian society might look like if it had been permitted to grow, without outside influence, for another few millennia, and this becomes a fascinating novel on several levels.
