Spoiler:

As Jane Marple sat basking in the tropical sunshine she felt mildly discontented with life. True, the warmth eased her rheumatism, but here in paradise nothing ever happened. Then a question was put to her by a stranger: 'Would you like to see a picture of a murderer?' Before she has a chance to answer, the man vanishes, only to be found dead the next day. The mysteries abound: Where is the picture? Why is the hotelier prone to nightmares? Why doesn't the most talked-about guest, a reclusive millionaire, ever leave his room? And why is Miss Marple herself fearful for her life?

Of note: A Caribbean Mystery introduces the wealthy (and difficult) Mr Jason Rafiel, who will call upon Miss Marple for help in Nemesis (1971) -- after his death.

As the blurb mentions, this book introduces Mr. Rafiel, who will be central in the plot of Christie's later book, Nemesis, which is one of my favorites of hers...
