故事简介(英文书籍)
Miss Marple receives a letter from the recently deceased Mr Jason Rafiel, a millionaire whom she had met during a holiday on which she had encountered a murder, which asks her to look into an unspecified crime; if she succeeds in solving the crime, she will inherit £20,000.
Rafiel, however, has left her few clues, not even when or where the crime was committed and who was involved.
