When Ignatius B. Grumply rents 43 Old Cemetery Road to overcome his writer’s block, he is hoping for quiet. Instead he meets 11-year-old Seymour Hope who has been left there by his parents and the house’s other inhabitant: a ghost named Olive C. Spence and Seymour’s cat, Shadow. They are not pleased to meet I. B. Grumply. The story is told through letters between the characters, news stories, and advertisements. It is marketed to 9 to 12-year-olds, but much older readers will also enjoy the humor.
