Emsie and Emily are talking about Evan who is female rather than male as you might think. They're wondering if Evan is a descendant of Emma, although it is obviously not through Edwina who is Edwin's illegitimate daughter. There is that strange resemblance to Elizabeth though and, to confuse matters even further, a nanny called Elvira.
I'd had a busy day and the library trip had to be restricted to dropping six books on the counter and picking up the first six from the returned books trolley. One of these was "Emma's Secret" by Barbara Taylor Bradford. It's number four in her Emma Harte series, of which [[''A Woman of Substance]] '' is the first, best and most famous.
On her death bed Evan's grandmother tells her to find Emma Harte as she has the key to her future. Evan goes to London only to discover that Emma has been dead for thirty years, but as she's come all the way from New York she decides she might as well take a job at the Harte department store. Everyone she meets comments on her physical likeness to the Harte family. During the Second World War Evan's grandmother had been Emma's secretary and it's hoped that Emma's diaries from that period will provide some clue as to if and how Evan is related to the Hartes.
