The Mysterious Mr Quin By Agatha Christie

ISBN: 0007354649

Published By Harper Collins

This collection of short stories features Mr Satterthwaite, an elderly gentlemen with a comfortable life. He is a great people watcher, and one New Year's Eve at a house party he meets Mr Harley Quin. The stranger helps Mr Satterthwaite solve various mysteries, simply by helping him see things in a different way.  Mr Quin, by his own admission comes and goes, and in each story he becomes more and more paranormal, seemingly appearing from nowhere.

The mysteries themselves are straightforward, and all the clues are there for the reader to solve. What is more of a riddle is the relationship between the two men. Is Mr Quin really some sort of supernatural being, or is he an extension of Mr Satterthwiate's own mind as it works through the problems? This is never really resolved, and I rather liked the fact that it was up to the reader to decide.
