The town of Limstock seems to be an ideal place for rehabilitation. So, after a plane crash, Jerry Burton decides to settle here with his sister Joanna, who accompanies him. But soon, a series of anonymous letters of defamation disrupt the quiet flow of local life. One of the recipients eventually commits suicide, presumably because of the outrageous content of the letter. But the turmoil doesn't stop there: her maid is found murdered.

It seems that someone in the community is behind the murder. Jerry tries to help the police get on the trail of the anonymous person. As long as he or she is at large, the people of Limestock cannot trust each other. However, only Jane Marple is able to uncover the secrets and get to the bottom of the case. About a billion copies of her works have been sold in English, and another billion have been translated into 100 foreign languages. She is the most popular author of all time. Her books are second only to the Bible and the works of Shakespeare in terms of the number of reprints.
