The lack of high regard for D.K. Broster's supernatural writings is an enigma. I suppose during the hey-dey of the ghost story, many women writers were overlooked due to the politics of the time. Whilst today women writers in this tradition are only celebrated if their stories ramble on about how oppressed women are for 30 pages (again, politics of the time). More's the pity, for their is some truly great material here.
D.K. Broster's supernatural tales are very eclectic in style. The title story, about an artist who's suffering demonic visitations by some slug-like creature recalls some of Sheridan Le Fanu's finest works, especially 'Green Tea' and 'The Familiar'. 'From The Abyss' on the other hand, is a very subtle tale of doubling, which has strong shades of Henry James about it. There's a good balance between the traditional and the psychological in this book, all of which make for great winter reading (preferably, of course, by a roaring fire).
Broster's prose is void of the banal simplicity of most 20th century fiction and her sentences are a joy to read. Her style feels much closer to that of the Victorian period that typical post-war literature, making it all the more enjoyable. Some of her stories have quite clear points to them, others are far more ambiguous and uncertain, which means 'Couching At The Door' has a wide range of appeal.
All in all, I'd say D.K. Broster is one of the greatest rare gems. Her stories linger in your mind for a long-time afterward due to the unanswered questions they pose, and their psychological intrigue. For £2.99 you can't go wrong with this.
