Ghostly visitors, messages from the dead, an attractive vampire, and an evil character from fiction who appears to avenge himself on his author (clever, that)--such are the well-bred haunts to be met in Hoke's latest grab-bag collection. Included also are a sort of capsule Kafka, an incidental Graves, two reprints from Miriam Allen de Ford's Elsewhere, Elsewhen, Elsehow, Bradbury's mechanical ingenuity ""The Changeling,"" mystery writer Stanley Ellin's variation on the always fascinating theme of a vicious child, and Waugh's ""The Man Who Liked Dickens"" which is not to be missed but then has not heretofore been in any danger of oblivion. A filler.
