An unseen intruder breaks into the Drew home, stealing documents
that will allow Nancy's aunts, Ruby and Lela, to sell their
farm. While Nancy's father lawyer Carson Drew, goes to the
State Capitol to replace the papers, Nancy heads to the Farmhouse
where she is plunged into a series of strange events that
lead her deeper and deeper into danger. Clanging chains, secret
panels and suspiciously hostile neighbors are only part of
this seemingly unsolvable crime against the Drew household.
