The Haunted Bookshop is a suspenseful novel set in Brooklyn around the time of the end of World War I. It continues the story of Roger Mifflin, the book seller in Parnassus on Wheels.The title refers to the ghosts of the past that haunt all libraries and bookstores: "the ghosts of all great literature." Throughout the novel Morley, through the character of Roger Mifflin, makes reference to the knowledge and wisdom that one can gain from literature.To the Booksellers Be pleased to know, most worthy, that this little book is dedicated to you in affection and respect. The faults of the composition are plain to you all. I begin merely in the hope of saying something further of the adventures of Roger Mifflin, whose exploits in "Parnassus on Wheels" some of you have been kind enough to applaud. But then came Miss Titania Chapman, and my young advertising man fell in love with her, and the two of them rather ran away with the tale.
