First published in 1964

The tiny Caribbean island of St. Honoré is a tropical paradise. But for Miss Marple, enjoying a well-earned rest from her busy life in the village of St. Mary Mead, it is a place where nothing ever seems to happen.

The next morning, a servant finds him dead in his room. Doctor Graham concludes that the major died of heart failure, since he showed all the symptoms, and had a bottle of Serenite in the bathroom. As rumors begin to circulate, Miss Marple is not alone in suspecting that things are not as they seem. And when a death that is indisputably murder occurs, she finds an unlikely ally in the cantankerous crippled millionaire Mr. Rafiel
