Algernon Blackwood was a prolific writer across short stories, novels and plays. His passion for the supernatural and for ghost stories together with a fascination for all things in the occult and mysticism created some of the most enthralling works ever written. HP Lovecraft referred to his works as that of a master. Henry James in referring to The Bright Messenger said "the most extraordinary novel on psychoanalysis, one that dwarfs the subject." Many other authors similarly lauded him. Today his works are beginning to regain their former popularity. Here we publish one of his classic novels, The Extra Day, one of a number of books that any fan of the occult should read.
