That's an Agatha Christie Dame Agatha Mary Clarissa Mallowan, Lady Mallowan (née Miller, 15 September 1890 – 12 January 1976), usually known by her first married name, Agatha Christie, was an English author known for her 66 detective novels and 14 short-story collections, particularly those revolving around fictional detectives Hercule Poirot and Miss Marple. She is widely regarded as one of the greatest writers, particularly in the mystery genre. title! I read the book over the weekend and got a glimpse of the talent of the Queen of Crime. This was my first entry into the world of Agatha Christie. She has a very nice writing style, great attention to detail, and is an excellent storyteller. :)
