Here is a nice selection of ghost stories from author/ghost hunter, Elliott O'Donnell.
Mr. O'Donnell wrote several popular novels but specialized in what were claimed as true stories of ghosts and hauntings. He had a psychic experience at the age of five, in a house where he saw a nude elemental figure covered with spots. As a young man, he claimed he was half-strangled by a mysterious phantom in Dublin.
He eventually became known as an authority on the supernatural and he was called upon as a ghost hunter. He also lectured and broadcast (radio and television) on the paranormal in Britain and the United States.
His view on the subject: "I have investigated, sometimes alone, and sometimes with other people and the press, many cases of reputed hauntings. I believe in ghosts but am not a spiritualist."
This book was published in 1912 and covers 17 cases that he investigated in Scotland.
I'm a sucker for ghost stories, especially
true ghost stories. I'm halfway through this book, and I have to admit that some of these are really spooky. Much creepier than I thought they would be—especially a story describing a certain young lady in the phantom regiment of Killiecrankie.
Best if read alone, at night and with the wind howling outside.
