I agree with you completely regarding 1-3,
Formendacil, with 3 certainly being the '
most salacious'.
When I first read that story, I felt, like you, that it resembled something written by Agatha Christie.
I then thought that a hobbit version of Miss Marple would work very well. Perhaps Dora Baggins, Frodo's aunt, who liked writing lots of letters full of good advice, would fit that role?
