Agatha Christie Series 3: One, Two, Buckle My Shoe Traditional Cache

I am an avid fan of Agatha Christie, having read my first book of hers 'Death on the Nile' when I was in my early teens.
I have read and own all of her books and also have the DVDs of both the Poirot Series and the Miss Marple Series.
I am aiming to place a cache to represent each of her books.
The location or container will be linked in some way to the book.
The description for each will be taken from the relevant book.

One, Two, Buckle My Shoe

'Hercule Poirot disliked his dentist, but one of his patients liked Mr Morley even less - and shot him just after Poirot left his office.

Was it the mysterious, unpleasant Greek? The wild young American who looked like a murderer? The rich banker? Or the ex-actress with the buckle on her shoe?

This cache is placed with the name of the victim in mind.
