I'm not sure specifically what the 'bishop oldes story' is as the name is rather unclear. It could be a story related to an old bishop, perhaps about his life, his deeds in the church, or some events associated with him in a particular historical or religious context.
Sorry, without more information, I can't really share the key elements. It could be that the key element is the bishop's character, like his kindness or strictness in religious matters.
The 'ghost in a ghost story' often represents the core of the mystery and fear. It is the element that drives the plot, creating an atmosphere of the unknown and the supernatural.
That's a tough one. Different ghost stories have different actors playing the ghost. You might need to provide more details about the particular story for a precise answer.
I don't have that information off the top of my head. Maybe you could tell me more about the ghost story, like the title or where it was shown, and then I could try to help you figure out who played the ghost.
Depends on how you define a ghost story. 1899 has some mysterious and spooky aspects, but it's not a traditional ghost story in the conventional sense. It's a multi-layered story with elements of the unknown and the paranormal.
