Contains the first two volumes of the author's ghost stories, "Ghost Stories of an Antiquary" and "More Ghost Stories of an Antiquary". This collection includes such tales as "Count Magnus"; "Number 13"; "Casting the Runes"; "Curse of the Demon"; and "Oh, Whistle, and I'll Come to You, My Lad".

The only annotated edition of M. R. James's writings currently available, Count Magnus and Other Ghost Stories contains the entire first two volumes of James's ghost stories, Ghost Stories of an Antiquary and More Ghost Stories of an Antiquary. These volumes are both the culmination of the nineteenth-century ghost story tradition and the inspiration for much of the best twentieth-century work in this genre. Included in this collection are such landmark tales as "Count Magnus," set in the wilds of Sweden; "Number 13," a distinctive tale about a haunted hotel room; "Casting the Runes," a richly complex tale of sorcery that served as the basis for the classic horror film Curse of the Demon; and "Oh, Whistle, and I'll Come to You, My Lad," one of the most frightening tales in literature. The appendix includes several rare texts, including "A Night in King's College Chapel," James's first known ghost story.
