When I registered back in 1998 (11 years ago!) the Monica scandal and assorted mysteries were the main topic on the forum.
I chose Miss Marple because she was a detective who liked gardening and sensible shoes, just like me! I have retained the Miss Marple name all these years.
Thanks for asking!
My wife named her sea anemone Miss Marple years ago.
We were just talking about it last night. Funny.
