A Restless Beginning

Ready for Another Case
An Unexplained Feeling
Nancy Drew feels nervous and restless before anything unusual happens. She interprets her mood as a longing for another adventure.
A Case Arrives
Nathan Gombet’s hostile visit soon gives that longing a real object. Nancy must defend her father’s integrity before she has the facts to understand the dispute.
Learning the Background

Context Before Judgment
A Familiar Witness
Allie Horner recognizes Nathan and describes his miserly habits and dispute over the railroad land. Her account supports Nancy’s distrust without yet proving a crime.
A Threat in Perspective
Nancy sees the railroad bridge and considers the damage Nathan might cause. She learns to treat his threats seriously while distinguishing suspicion from established fact.
Testing the Haunting

Investigation by Elimination
Ordinary Explanations
Nancy checks screens, doors, windows, and rooms, testing whether mundane access points can explain the strange events. Each negative result narrows the possibilities.
A Frustrating Dead End
The searches reveal no entrance, and Nancy begins to question whether she has missed something obvious. The failure strengthens her resolve to search more carefully rather than accept the sisters’ fears as proof.
Risking the Other House

Evidence Through Risk
A Deliberate Infiltration
Nancy decides to enter Nathan’s house when he leaves, despite the servant’s presence. Her attempt to investigate is dangerous because she has not yet established what she will find.
An Accidental Clue
The parrot draws attention to her, and she hides in a closet. A hidden knob there reveals the passage, making a risky improvisation more valuable than her earlier planned searches.
Proof Before Accusation

From Theory to Evidence
Confirming the Openings
Nancy guides the sisters through the hidden stairs and identifies routes into private rooms. She connects the mechanics to the stolen objects and the apparent haunting.
A Case for Action
She insists on informing the police only after confirming the route. Her detective work turns a plausible theory about Nathan into a demonstrable case.
