No reader is likely to forget the occupants of *The Aquarium*, or the supernatural horror of *The Unpleasantness at Carver House* which deserves permanence as a contemporary classic in its genre. The psychological shock of *The Cocomaque* is as memorable as the awesome vision of *The White Pinnacle*, and the probing search in *The Random Quantity* has its counterpart in the spectacular bizarrerie of *The Player at Yellow Silence*. Whether in the brief scope of *Sequence* or the longer haunting of *The Singleton Barrier*, Carl Jacobi is always an artist at story-telling.
