Enhancing their credibility, many of the 20 horror stories in this annual collection are shaped by a hard-edged realism. The forces of evil come in several guises. The young German teenager in Cherry Wilder’s “The House on Cemetery Street” confronts the unspeakable after learning that her aunt, who hid their Jewish neighbors from the Nazis, later callously caused their deaths. In Ramsay Campbell’s futuristic “It Helps If You Sing,” the protagonist awaits emasculation by the agents of a fanatic evangelist who wants to rid the world of demon lust. In another story set in the future, “At First Just Ghostly” by Karl Edward Wagner, an alcoholic writer sees that he must remain sober in order to combat Satan and prevent nuclear annihilation. “Snow Cancellations” by Donald R. Burlesson features a young boy who watches the town disappear as a mysteriously malevolent blizzard advances toward his home. A snowstorm also figures in “The Horn,” a tense story by Stephen Gallagher. In others of these tales corpses make love to former lovers and long-dead rapists disinter themselves in order to attack new victims. Ian Watson, Kim Newman and Chet Williamson also contribute chilling tales.
