What was Edgar Allan book about the girl and boy ghost?

There isn't an Edgar Allan Poe story specifically about a boy and girl ghost. He is famous for his dark and macabre tales, but his stories typically feature one ghost or a spirit with a specific, often tragic, connection to a living character.

It's possible you're thinking of a different author or a story with a similar theme. Perhaps you could tell me more about what you remember about the story, like:

* What was the setting like?

* What were the ghosts doing?

* Was there any specific interaction between the ghosts?

* Did the ghosts have names?

With more information, I might be able to help you pinpoint the story you're thinking of.
