That's an Agatha Christie Dame Agatha Mary Clarissa Christie, Lady Mallowan (née Miller; 15 September 1890 – 12 January 1976), 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. :)
