In "Gunmen, Gallants and Ghosts" there is a series of stories generally entitled The Ghost hunter, which have the same central character. In addition to these four stories, there are four other stories of the occult, eight stories about crooks or spies and a passage which makes a story in itself from each of my biographies, "A Very Private Life of Charles II" and "Red Eagle", an account of the Russian Revolution. In addition, in this new Arrow edition, I have added seven articles on black magic, the unexpurgated versions of six which have never before appeared in print.
