Young women should not go alone on dark nights, even in Oxfordshire. But any prowling maniac would have had more than his work cut out if he had accosted Anathema Device. She was a witch, after all. And precisely because she was a witch, and therefore sensible, she put little faith in protective amulets and spells; she saved it all for a foot-long bread knife which she kept in her belt.
