People say that funny lights have been seen at the old abandoned Cliff Castle. Of course, as soon as Peter, Pam and their cousin Brock hear this they are determined to solve the mystery even though it means pitting their wits against the unknown enemy that awaits them.
When Bob and Mary arrive at their Granny's for the summer holidays they are delighted. But this year their big, rough cousin Ralph is staying as well. One rainy day, Granny tells them about a beautiful necklace that disappeared 100 years ago, and soon Bob and Mary find a secret passage.
