Necromancers

In THE NECROMANCERS Robert Hugh Benson sets out to expose the dangers of &quote;Spiritism,&quote; interest in which had reached epidemic proportions by the early twentieth century. C. C. Martindale, S.J. commented that, &quote;It is in THE NECROMANCERS that he brings all his heavy artillery to bear on his professed enemy. Here again the uncanny enters, but rises to the heroic level, and achieves the horrible; and I will confess that I can think of no book which reaches so high a pitch of horror, unaided by alien elements.&quote; (Goodreads)
