Helen Hayes plays Agatha Christie's amateur sleuth Miss Jane Marple in A Caribbean Mystery. Recuperating from an illness at a resort in the Bahamas, Miss Marple makes the acquaintance of a genial British major (
Maurice Evans). When her new friend is murdered, Miss M takes on the case herself. She certainly has a carload of suspects this time, ranging from the near-bankrupt owners of the resort to a secretive hotel doctor. Originally titled Agatha Christie's The Caribbean Mystery, this TV movie first aired October 22, 1983. ~ Hal Erickson, All Movie Guide
