Here’s a book I read about in By the Book World Remembered that sounded intriguing.
Hind, Charles Lewis. The Enchanted Stone. Adam and Charles Black (London), 1896. First edition hardback, a Very Good copy with repaired hinges, slight spine fading, bookplate on insider front cover and uneven foxing on front and rear free endpaper. By the Book World Remembered, page 106, which describes it as a “Fantastic tale of a vast Chinese city under London.” Tietler, By the World Forgot, page 53, which notes that this UK first edition has an extra chapter not in the American edition. Bleiler, Checklist (1978), page 100. Reginald, page 253. A very odd sounding Wainscot (to use Clute’s term from The Encyclopedia of Fantasy) indeed. Bought off the Internet for $36 plus shipping from Canada.
