Seven-year-old Suzanne Collier has great insights and a quirky personality that fit perfectly with her dream of wanting to be a detective. Motivated by her desire to solve crimes, Suzanne drives everyone crazy by asking too many questions. But when she stumbles upon her biggest mystery yet, Suzanne begins a quest to understand why people do the things they do. As Suzanne attempts to solve the case of a dead hobo in an Illinois cornfield, she uncovers clues, helps two friends in need, and hopes she can solve the case before someone else gets hurt. Her next case comes quickly as Suzanne is led to help unravel a highway crime in Michigan where she saves a dog's life and learns the consequences of her thoughtless comments. In her final case, Suzanne exposes evil motives amid a dinosaur dig in Kansas, all while facing big changes as her family prepares to move to Minnesota-the place where Suzanne is certain witches, vampires, and frozen souls reside. In this young adult novel, a girl turned amateur detective must rely on her skills and face her fears while attempting to solve three mysteries.
