And Then There Were None by Agatha Christie. Ten people are invited as guests or hired help on Indian Island, off the British Coast. As they are all assembled after their arrival a voice suddenly announces that they are charged with murder indictments and the voice proceeds to list each of their victims. At this point they realize they are stranded on the island in the hands of a yet-unseen, mysterious and obviously “dangerous and probably insane” host. This isn’t the vacation they signed up for. They’re ready to leave. Unfortunately the boat that delivered them has left and won’t return until the following day.
One person quickly winds up dead, and the group chalks it up to suicide, but then another person is found dead, and then another. It takes a bit before they realize how a poem about ten little Indians is directly connected to their situation. Soon they start suspecting each other all the while hoping the boat would come back. But, no such luck. The weather and circumstances have turned dicey. And this is the time before cell phones, so they couldn’t contact anyone on the outside even if the weather allowed for a rescue mission to come to their aid. As the title suggests, they were sitting ducks, picked off one by one. But how did they die and more importantly, who and how was the serial killer orchestrating their deaths? You’ll have to read it to find out.
