Nancy gets that opportunity when she is asked to help solve the ghostly activity at the Twin Elms mansion. Can she help explain the creaking footsteps, exploding light bulbs and the ominous creature? Is it the handiwork of high-school bully Derek Barnes? Or is it possible that the ghost of original owner Malcolm Colfax is back for revenge? Recruiting her best friends George and Bess, along with local "mean girl" Helen, Nancy Drew is on the case!
