'When Fox is a Thousand' is a spirited retelling of an old Chinese folktale. In Larissa Lai's lyrical and enchanting novel, a fox spirit comes to haunt Artemis Wong, a young woman living in contemporary Vancouver. The Fox brings with her the history of another haunting, that of the T'ang Dynasty poet Yu Hsuan-Chi, who was accused of having murdered the young maid servant who once worked for her.
