'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.
