Poirot & Miss Marple

My most treasured TV series collection.  When I was in primary school, I would run home on a Saturday afternoon to catch Poirot solving a seemingly impossible case, with such charm, and a touching plot. Hercule Poirot's grey cells and Miss Marple's wittiness.  Georgous backdrop in the days gone by and beautiful cinematography.  Very intriguing and humane storyline.  What can better accompany a nice cup of tea and homemade Swiss meringues?
