Thankyou youngmrquin, It wasn't a Girl's school, after all I am a bloke but whenever I read Cat among The Pigeons I think of the school, The School made me think Meadowbanks is the same period although I read the book years after leaving it. I started reading Agatha Christie books in my Teens too and now I am 46.
Sadly we society today seems to encourage us to judge the past and compare with Standards of Today so the question of what Agatha Christie thought of Homosexuals and whether X or Y is a Homosexual or a Lesbian is going to be raised more and more and maybe detract from her writing
That was one of my criticisms I had of some of the filmed adaptations that were done for the 21st century BBC films.
*Body in the Library did not have it and they changed the plot to include it in the film
*Murder is Announced does not have it directly said for the characters of Miss Hinchcliffe and Miss Murgatroyd but the film made it blatent.
*Nemisis did not have the murderer' motive as gay but yet the last filmed adaptation made it distastefully so !
*The Moving Finger's 2006 adaptation made one of the characters fey
*The 2010 Mirror Crack'd made reference to it--almost in a blackmailing way by Miss Marple to the male secretary towards the end of the film (very uncharacteristic of Miss Marple!)
and in a recent re-watching of the Poirot Cards on the Table I noted that the murderer's motivation were changed to be of a homosexual nature.
Not sure why they deemed it necessary to change the plotlines.
Nemesis (along with "The Clock Strikes Twelve") deals with an unhealthy kind of love, where love could go when taken to the extreme -- obsessive love. It's a theme that Christie often explored throughout her career but in Nemesis she shows how far and dark it could get. A flawed book but beyond that it's one of Christie's finest of her later books.Yes, the element of the over controlling or over-obsessed parent or guardian appears in "Ordeal by Innocence", and in the story "The herb of death". Unfortunately, this is a situation that happens, in different variations, in real life.
