Addio Miss Marple

Currently we are enjoying a spate of Joan Hickson's Miss Marple series on our free to air channel. I have watched the other adaptations of Agatha Christie's novel with Geraldine McEwan and while they were fine performances (story lines got a bit muddled) the JH ones are bringing back the original plots and stories. Only one thing is grating me is that the character of Gwenda supposedly from New Zealand is speaking with the most dreadful "Stryne" (Australian) accent. Good grief, the producers only had to go down to Earls Court and pick out a few Kiwis to hear the difference. Also, I get the picture that Gwenda was from a more refined family ( upper middle class) in which her accent would have been more cultured with a hint of "fush & chips" in it. Other than that I'm very much enjoying JH version.
