A Caribbean Mystery places the sweet Miss Marple in a tropical paradise. In the beginning Miss Marple is quite bored, even though everybody treats her quite nice. Excitement comes from nowhere when she realise that the death of the old Major Palgrave might not be quite that natural as everybody believes (or want to believe). The only clue is a conversation with the victim (when she wasn't actually listening carefully) and a missing picture of "a murderer" which the Major had. Things are getting pretty complicated with the death of the servant Victoria Johnson (which was trying the blackmail the murderer) and the death of a woman, which came on the island with her husband and one other couple. More than that, is appears that their host doesn't remember where she was during the murders, but her husband is trying to protect her.
In all this Miss Marple can only count on an old, rich and arrogant man. Or can she ??
