Murder at the Vicarage

One of my all time favorite authors is Agatha Christie and today I am starting to read "Murder at the Vicarage". This is a Miss Marple mystery and a very good read. When Col Protheroe is found murdered and though he is not well liked by the St Mary Mead villagers they never expected his murder. Miss Marple uses her cunning and knowledge to find who is behind the murder. Always an intriguing read. I recommend any of Agatha Christie's books. Miss Marple is one of my favorite of her sleuths. A little older woman that can be inconspicous which leads to her being able to investigate easier. What is your favorite Agatha Christie read or sleuth?
