The Word Haunted

The Word Haunted
A name for fear
Fenton Prentice calls the shadow a haunting because he cannot explain the movements in his apartment. The word expresses both an interpretation and his distress.
A problem of evidence
The boys do not immediately accept a ghost, but they do not ridicule the client. The story treats fear as real even when its cause remains uncertain.
The Key and the Shadow

The Key and the Shadow
One intrusion explained
Mrs Bortz’s duplicate key accounts for the opened desk and moved papers. Prentice briefly concludes that this human snooping explains the haunting as well.
More than one cause
The later return of the shadow shows that the first solution is incomplete. The story resists the comforting assumption that one explanation must account for every event.
An Apparition Observed

An Apparition Observed
Shared perception
Jupiter Jones sees a darker presence in the den and Prentice is relieved that someone else has witnessed it. Their agreement strengthens the report without identifying its cause.
Competing explanations
The figure resembles Sonny Elmquist, but he appears to be asleep in his own apartment. The haunting becomes a puzzle at the boundary between perception and physical possibility.
The Wanderer Theory

The Wanderer Theory
A framework offered
Professor Eugenia Lantine describes astral bodies that may appear to move while the physical person sleeps. The account makes Elmquist’s apparent double presence conceivable.
No proof of identity
The theory does not demonstrate that Elmquist is a wanderer or that he intends harm. It gives the investigators a possibility to test, not a verdict.
Quiet Without Certainty

Quiet Without Certainty
The disturbance ends
Prentice reports peace after Elmquist and Mrs Bortz leave the building. The immediate emotional burden of the haunting has lifted.
A question remains
The absence of further visits cannot prove what the shadow was. The story closes the practical problem while preserving uncertainty about the supernatural one.
