This is an automatically translated description

An old friend asks Miss Marple for help. She is convinced that her sister, Carrie Louise, is in danger, though she can't explain what kind of danger. So Miss Marple arrives at Stonygates Manor, which Carrie Louise's husband has turned into a shelter for juvenile delinquents. However, it turns out that they are not the ones who threaten her client. After dinner, a quarrel breaks out among the house guests and shots are fired. But the real trouble happens at night... Well, Miss Marple has come to this house for a reason. She will find the one who started the deadly game! 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.
