The Gap in the Curtain John Buchan is remembered for his spy thrillers like "The 39 Steps" but he also wrote tales of the supernatural. Whether The Gap in the Curtain is a supernatural tale, or science fiction, or horror, is difficult to say. A brilliant but possibly slightly unbalanced scientist discovers a means of lifting the curtain for a moment and gaining a glimpse of the future. This discovery allows six guests in his country house to see, for a brief instant of time, a page from a newspaper from one year in the future. The book then follows the life of each of the six people up to that date a year in the future, and examines the way they deal with the knowledge they have gained. The trick to it is that what they each see is an isolated fact, taken out of context. It can enlighten, but it can just as easily mislead. They know one thing that is going to happen, but they don't know how and why it will happen. The knowledge turns out to be surprisingly dangerous.
