Leira MacGregor is anxiously awaiting the arrival of two new families into her neighborhood. She is hoping desperately that someone will finally move in with children her own age. They may be able to help her to solve the mystery of Grimly Manor. The spooky manor, which was built long ago, has an ancient cemetery behind it. According to whisperings, there is a scary old man who lives there, but no one has seen him except on Halloween. Candles flicker in the night, and on holidays, decorations appear around the manor like magic. Families in the neighborhood try and ignore these strange happenings. Over the years, children have only been able to conquer their fear on Halloween by knocking on the decaying door. When the door was opened, they were ‘greeted’ by someone in a frightful mask and costume with vicious growling in the background. It’s up to Leira to find someone brave enough to help solve the mystery. Little does she imagine what adventures lay in her path!

In Arizona, the girls are invited to spend three nights in the mountains camping with Leira’s eighteen-year-old cousin Luke who’s an eagle scout. The adventure brings them in contact with Indian lore, reptiles, animals and much more. But the trip turns into a nightmare when the group is confronted with mysterious happenings and a tragic accident finds them in mortal danger!
