Elsie is Harker's daughter. For all we know, Harker could have had three or four children all safely lodging with the vicar in St Awful or tucked away in boarding school and having a better time of it than they would have had with a globe trotting, glory seeking mom more concerned with the monetary worth of a find than its scientific or historical value. That said, I got a kick out of Harker's journal, loved the photos (Was that someone in drag as Harker?) and loved how much clout Harker clearly had with the Royal Society. She must have been something of a celebrity archaeologist, not at all the type to be bothered by leaving her children with the grandps for years on end. I quite liked Harker with her Bronze Age pelf around her neck and her nose in the air. "Kids, what kids? Oh, those. Yes, must remember to write after Christmas and see if their camel ever arrived from Cairo. Perhaps the Pony Club will refrain from fussing if Elsie has a nonregulation mount." If taxed about leaving Elsie to the care of others, Harker would have sniffed and said, "Winston's moral compass was his nanny. Pass the cucumber sandwiches, there's a dear."
