Grimoire

A grimoire was a book of spells used by witches. Witches of a high-calibre would have their grimoire bound by their own skin, as Isaac Greatorex did. His grimoire ended up in a private library, from which it was stolen by Margaret Wyndham. Greatorex planned to use it to resurrect himself, but it was instead used by Wyndham and Liz Shaw to destroy him. (HOMEVID: Ghosts of Winterborne)
