What Mrs. McGillicuddy Saw!

This was a draft post that I never finished.  It's not a total review (it's missing the numbers, for one thing) but I figure I might as well post it. 

What Mrs. McGillicuddy Saw! by Agatha Christie details the investigation that follows Mrs. McGillicuddy seeing a woman being strangled in a passing train.  Though the body is not found, Miss Marple is convinced that the murder actually happened and enlists Lucy Eyelesbarrow to serve at a certain house where the body may be found.  Lucy actually finds the body, and the case that follows baffles the police and everyone concerned - except Miss Marple.

Lucy Eyelesbarrow is an practical, efficient girl, though lacking in Miss Marple's particular mental abilities.  Her trust in Miss Marple's good judgement is magnified through the book, first when she finds the body and second when Miss Marple actually solves the mystery.  She could be considered eccentric when she turns down a steady position for this more exciting and definitely more dangerous position, given that someone has been killed, and the murderer could kill again.
