One Dreadful Night presents a mystery that is deftly woven into the underlying web of supernatural horror. From the moment that a strange face is glimpsed peering from the window of the laboratory at "Restormal," the novel builds gradually to a climatic resolution of sheer terror as the identity of the mysterious woman lurking in the dim-lit corridors is revealed in a shocking denouement. One Dreadful Night is part of that small group of novels such as Mark Hansom's The Beasts of Brahm wherein the elements of the mystery novel and the supernatural tale are blended seamlessly to create a genuine thriller that will keep the reader turning pages while leaving all the lights on
