内容简介：
When Dr. Foster purchases a huge log mansion on a mountain west of Little Rock, AR, the adventure begins. The old house is reputed to be haunted with strange lights being seen up there at night and mysterous sounds not unlike that of moans and of digging. The Foster Twins invite their cousin, Dylan, to help them investigate and run into a hooded, knife throwing shadowy figure. With a skull being discovered, an arrow narrowly missing Dylan and constantly being followed by a mysterous black Lincoln, the Twins, their cousin, and their adventurous mom, have all they can handle in this fast-paced adventure.
