Miss Marple is visiting a friend in the village of Little Ambrose. On the bus there she meets a young man, Eddie Seward, and finds him intelligent and sensitive company. However, a few days later, Eddie Seward is found dead on the banks of the river near the golf club, and it looks like murder. A short time after that, the most disliked woman in the village, Mary Pritchard, is found dead, poisoned. There are several suspects but her husband, George, eventually confesses to the crime. He is due to be sentenced when Miss Marple realises that he isn't the murderer and races to prevent him from being found guilty.
