John Buchan (1875–1940), although most famous today for his spy novel The Thirty-Nine Steps, was esteemed in his day as “probably the most modern exponent of the short story, which he has developed and brought to artistic perfection”.
The Watcher by the Threshold,among the tales are such classics as “Tendebant Manus”, “The Grove of Ashtaroth”, “The Green Wildebeest”, “The Wind in the Portico”, and the chilling title story; tales in which unspeakable evil lies in wait for the unwary, brought to elegant life by the writer who, in the words of David Daniell, was “a Christian who had glimpsed the Devil”.
