Christopher Morley 
Haunted Bookshop 

The Haunted Bookshop speaks of the ghosts that inhabit all places of books – "the ghosts of all great literature." Christopher Morley’s suspenseful 1919 novel continues the story of the bookseller from Parnassus on Wheels, Roger Mifflin, whose character underlines the wisdom and knowledge to be gained from literature and makes allusions and references to many famous works.
