Nancy and a whole group of her friends are determined to solve a series of ghost mysteries, all of which have appeared suddenly in the same geographic vicinity. They find a tie between the mysteries, and attempts to buy pieces of property at far below their value (a common Nancy Drew theme). It seems that someone with a lot of technical skill has been rigging up a series of "ghosts" and using them to scare people, along with stealing a variety of valuable shells for resale. As Nancy and her friends attempt to evade danger from bombs and fireworks, they rush to track down a gang of increasingly slippery crooks. ( )
