Readers of Robert Aickman's bestselling series, Fontana Great Ghost Stories, will know what to expect from this original and electrifying author. In Powers of Darkness Mr. Aickman is again concerned with the macabre and the unearthly, with Things that fly, or scrabble on the roof, or merely manifest. The instruments of communication with the world beyond range from a prosaic telephone receiver to a mysteriously glowing horse's eye, the settings vary from a Birmingham suburb to a Greek Island, but in every case readers will experience that authentic chill which is the hallmark of the well-written supernatural and the work of the author of Dark Entries.
