Samantha opened the door, and something hopped and shuffled into the room. Something round and black and furry ... In the cellar of Park House, the old mansion where orphaned Samantha has been sent to stay with her disagreeable Aunt Daisy, there are hundreds of bogwoppits – believed extinct, up till now. Aunt Daisy wants to get rid of them all, but Samantha grows very fond of one and can't bear to part with him. It seems as though Samantha and her aunt will never agree – until one day Aunt Daisy mysteriously disappears and Samantha plans a Big Rescue Operation!
