A Caribbean Mystery - Agatha Christie.

"Would you like to see a picture of a murderer?" So asks a stranger of Miss Jane Marple while she is vacationing on luxurious St. Honore. Before she has a chance to answer, the mystery man vanishes, only to be found dead the following day. Now Miss Marple is asking the questions: What happened to the curious photo: Why is the hotelier prone to nightmares? Why doesn't the most-talked-about guest, a reclusive millionaire, ever leave his room? Any why is Miss Marple fearing for her own life?
