One of the former British writers of supernatural tales in the twentieth century, Algernon Blackwood (1869–1951) wrote stories in which the slow accumulation of telling details produced a foreboding atmosphere of almost unendurable tension. Blackwood's literary renown began in 1908 with the publication of a highly successful collection of stories, John Silence—Physician Extraordinary, featuring a "psychic doctor." This volume contains the last three of the John Silence stories: Secret Worship, The Camp of the Dog, and A Victim of Higher Space.
