The Quest of the Missing Map

When Nancy agreed to help her friend Ellen with a job decision, she had no idea that it would lead her to a new mystery to solve. Ellen's father was one of a pair of twins who inherited halves of an old treasure map. But, the twins had been separated many years before, along with the map pieces. Also, Ellen's new job was strangely involved in the case. Nancy and her friends worked together to outwit clever thieves, intent on putting the pieces of the map together and locating the treasure for themselves at all costs!
