'For three minutes you will turn your eyes inward – into the darkness of the mind which I have taught you to make.Then – I will give the sign – you will look at the paper.There you will see words written, but only for one second.Bend all your powers to remember them.'What begins as a welcome, if slightly dull, weekend at his friend Lady Flambard's house in the Costwolds becomes for Sir Edward Leithen something altogether more intriguing.A fellow guest – the brilliant Professor Moe – enlists the help of Leithen and his companions in an experiment.If they do as he says, each will get a glimpse a year into the future in the pages of The Times. One of Buchan's most unusual novels, The Gap in the Curtain is a tense tale of unexpected from the author of The Thirty-Nine Steps. With an introduction by Stuart Kelly. This edition is authorised by the John Buchan Society.
