Van Richten's Monster Hunter's Compendium Volume Three

From the back of the book: "Demons, devils, and murderous hags stretch their hideous claws towards AD&D game characters everywhere, while craft Vistani and secretive witches, hatch their plots in this tome, the third volume in Doctor Van Richten's guides for monster hunters. This compilation contains the complete and updated texts of Van Richten's Guide to Fiends and Van Richten's Guide to the Vistani, with a surprise-the previously unpublished Van Richten's Guide to Witches, all for use in any AD&D campaign."
