A Scottish barrister gets entangled in a web of deadly superstition and danger on a small Greek island in this novel by the author of The Thirty-Nine Steps.   Though Sir Edward Leithen is not one to take superstition seriously, he is sympathetic to his friend Vernon Milburne, who has been plagued by a recurring nightmare since childhood. Now, as the two men embark on an Aegean cruise, the dream’s disturbing portents seem to be coming true in ways neither man could have imagined.   In Plakos, Greece, Englishwoman Koré Arabin is in grave danger. The islanders believe her to be a witch, and it is up to Edward and Vernon to save her. But the more they learn of Koré’s family history, the closer they come to uncovering the evil that lurks in her island home.   First published in 1926, The Dancing Floor continues the saga of  Sir Edward Leithen, John Buchan’s popular character featured in The Power-House and John Macnab. Here, Buchan explores themes of fallacy and reason, paganism and Christianity.
