A Name and an Address

A Name and an Address
The Report
Hal gives Inspector Boyne Lars's name and the address of the fourth-floor rear apartment. He asks the police to investigate but offers no account of how he reached his conclusion.
Deliberate Omission
Hal keeps his window out of the explanation, preferring that the police investigate from the street. This protects his privacy but leaves them without the observations that shaped his theory.
A Witnessless Departure

A Witnessless Departure
Secondhand Accounts
Neighbors and the building superintendent repeat that Anna left for the country. None can say they personally saw her depart.
The Station Check
Boyne sends someone to verify the train story, but the account remains dependent on Lars's claim that he bought a ticket and saw his wife off. The inquiry has leads, not confirmation.
The Search and the Postcard

The Search and the Postcard
An Empty Search
Officers enter Lars's flat while he is out and find nothing that establishes a crime. He returns without apparently noticing their visit.
An Ambiguous Message
A postcard attributed to Anna appears to support the journey, but its date is blurred. The investigation has reassuring testimony and paper, yet no verified sighting of the missing woman.
The Witness Is Attacked

The Witness Is Attacked
A Threat Becomes Immediate
Hal's tests persuade him that Lars is reacting to evidence someone has entered the flat. The telephone line is cut, leaving Hal unable to summon help.
An Improvised Defense
Unable to rise from his chair, Hal arranges a bust and blanket to disguise his position. Lars fires, shattering the decoy and turning the investigation into a fight for survival.
Recovery Upstairs

Recovery Upstairs
The Search Moves Above
Hal identifies the raised cement kitchen floor in the unfinished apartment over Lars's home. Inspector Boyne and the police investigate the precise location.
A Case Reassembled
They uncover Anna's body and connect the physical discovery to the earlier deception. The investigation ends with a crime scene, a victim, and a reconstructed method of concealment.
