Agatha Mary Clarissa Christie was rather prolific in nature, and as a result, produced innumerable number of books, besides the 80 detective stories that she penned down. So ardent a writer was she, that even decades after her demise in 1976, a short Poirot story, only 5,000 words long was discovered in her seaside home attic, called 'The Incident of the Dog's Ball'. So, naturally it is difficult for a reader to keep a tab on which book of hers he has already read, and which he hasn't.

Her play "The Mousetrap" has been staged more than 23,000 times ever since it was first performed in 1952. The Mousetrap (1950) also available as aka Three Blind Mice The Mousetrap and Other Plays (1981) Other than these, the author penned down two non-fictional autobiographical pieces, wherein, she narrated the experiences and travelogues which not only made her the person she was, but also provided for the backdrops of her novels. She immensely enjoyed her voyages undertaken with her second husband, archaeologist Max Mallowan. So, in 1946, she published a book named 'Come, Tell Me How You Live: An Archaeological Memoir', wherein, she described her travel to Iraq and Syria at length. The second autobiographical piece was published posthumously in 1977, called 'Agatha Christie: An Autobiography', which was the literal encapsulation of her entire life and works in great detail. Christie had published only two books as Agatha Christie Mallowan in her life. One was 'Come, Tell Me How You Live: An Archaeological Memoir', and the other one was 'Star Over Bethlehem' in 1965, which was a mélange of short tales and poesie.
