//A museum is said to be haunted by whodunnit writer Agatha Christie’s ghost.
Staff in the author’s hometown claim that Christie’s books are mysteriously knocked off the gift shop’s shelves when no one is around.
A ghostly apparition of a woman has also been caught on camera — and CCTV has filmed leaflets being apparently hurled around.//

The staff seem to be in agreement but the camera image looks a bit suspicious to me so who knows? A hoax to drum up business … or something more?
