...and then there was x ne demek?

"And then there was X" is a phrase often used in mystery or horror stories to refer to a sudden appearance or event that changes the direction of the story. It implies the introduction of a new and unexpected element that marks a turning point in the narrative.

The phrase became popular with the publication of Agatha Christie's novel "And Then There Were None" in 1939, which tells the story of ten strangers who are invited to an island and gradually killed off one by one, leaving the remaining survivors to wonder who the killer is. The title of the novel refers to the nursery rhyme "Ten Little Indians" which ends with the lines "And then there were none."

Since then, the phrase "and then there was X" has been used in various contexts to refer to unexpected and sometimes ominous occurrences that change the course of events. It has become a common trope in popular culture, usually conveying a sense of suspense or unease.
