Imogene Duckworthy, eager PI assistant, wants to be on her own. She finds a rental house where her four-year-old daughter, Nancy Drew Duckworthy, and Drew’s pet pig, Marshmallow, are allowed. The rumors are that the house is haunted. It’s no rumor there’s a dead man in the bathtub when she inspects the house, though. A long-lost relative is the logical suspect, but can Immy let her Uncle Dewey be railroaded for a crime he, possibly, didn’t commit?
