Rosalie Muspratt (1906-1976), who also wrote under the name Jasper John, was the author of tales of horror and the supernatural and was later active in the Girls’ Magazine, the publication of the Modern Girls’ Club. Though two of her stories were anthologized in Montague Summers Supernatural Omnibus, the bulk of her writing has been exceedingly difficult to find, especially the material offered in the present collection, which consists of the entire contents of her collection Tales of Terror, of which only a handful of copies are known to exist, and the title story, which itself is quite rare.
