Jessica Fletcher, born as Jessica Beatrice MacGill, is a well-known author who writes under the pen name J.B. Fletcher. She is a fictional character from the popular American television series "Murder, She Wrote." Fletcher is not only an accomplished writer but also plays the role of an amateur sleuth in the show.\n \n Fletcher's writing career began with the use of an ancient Royal typewriter, a Magic Margin that had glass keys. However, as her career progressed, she upgraded her tools and purchased an Intel 80386 class computer that ran Windows 3.1, which was a popular operating system at the time.
There is a series of official original novels written by American ghostwriter Donald Bain and published by the New American Library, where the author credit is shared with the fictitious "Jessica Fletcher." The first novel in the series, "Gin and Daggers," was published in 1989 and contained several inaccuracies related to the TV series. For instance, it included a scene where Fletcher was driving a car, which she could not do as she never learned to drive. However, after fans pointed out the errors, the novel was republished in 2000 with most of the inaccuracies corrected.
