Ordered this because, for years, I had been teaching Blackwood's story "The Kit-Bag" as part of a Gothic module at Key Stage 3 at school and wanted to read more stories by the same author, who I knew very little about.
There is a good introduction about Blackwood himself and the edition includes the author's own 1938 introduction to his tales, which is excellent. He is a master of building up tension and suspense and the tales are worth reading for this alone. He is particularly interested in the power of Nature to come alive and take possession of people as a terrifying entity; read "The Willows" and "The Wendigo" to experience this for yourself. His skill lies in layers of small detail that slowly build up to create fear; don't expect lots of action, but do expect to feel your skin crawling and a sense of claustrophobia when reading these tales. You are relieved when a story ends, but you don't want to reach the end either!
This man was an unsung master of the ghost story genre-I recommend you to read these and more!
