Query: A great Miss Marple mystery

This was billed as Miss Marple's last case, but I think there were actually some written later. Still, it is probably one of her last. In this story, Miss Marple discovers that a millionaire that she had encountered in the Caribbean has died and has left a request for her to take on a task. She eventualy figures out what the task is and performs it for him. Once again, Miss Marple comes through. I like Miss Marple better than Christie's other characters, so this was a natural for me. Still, it's a pretty good story for anyone. Just remember that Miss Marple mysteries are not action stories; they are solved by reasoning and investigating. So, if you like lots of action, you may not care for this type of story.
