Timeline questions answered

Obsession Timeline Explained: Your Questions Answered

When does it happen, and why in that order? The questions people ask about the chronology of Obsession (1949): time jumps, flashbacks, cause and effect between scenes and the correct order of events, each answered with spoilers.

Q1

Why does Dr. Riordan keep Kronin alive for months instead of killing him immediately?

Riordan wants to commit the 'perfect crime' with no trace of motive or connection to himself. By keeping Kronin alive for months, he believes the investigation will go cold and any eventual disappearance won't be linked to him. The longer Kronin remains missing without a body, the less likely police will connect the case to Riordan's jealousy or his wife.

Foreshadowing: Early in the film, Riordan's meticulous planning and obsession with control establish his belief that patience is essential to avoiding detection.

  • perfect crime
  • kidnapping
  • motive
  • alibi
  • police investigation
Q2

How does Riordan plan to dispose of Kronin's body?

Riordan prepares an acid bath in the hidden room where Kronin is imprisoned. He brings hot water bottles filled with acid to ensure the body would be completely dissolved, leaving no remains that could be discovered. This method represents his vision of a flawless murder that would erase all evidence of the crime.

Foreshadowing: The preparations for the acid bath begin early in the captivity period, showing Riordan's methodical approach to murder.

  • acid bath
  • murder method
  • disposal
  • evidence
Q3

Why does Riordan consider killing his own dog Monty?

Riordan becomes paranoid that Monty will expose his secret. The dog follows Riordan to the hidden room during his daily visits, and Riordan fears Monty might lead someone to discover the imprisoned man. In a moment of cold calculation, he contemplates using the same acid bath prepared for Kronin on his own loyal dog to eliminate the potential witness.

Foreshadowing: Monty's noisy tracking of Riordan's movements during feeding visits establishes the dog as an accidental liability.

  • monty dog
  • paranoia
  • murder attempt
  • witness
Q4

How does Kronin survive Riordan's poisoning attempt?

Kronin survives because of Monty's intervention. During his captivity, Kronin had befriended the dog and apparently trained him. When Riordan poisons Kronin and prepares to use the acid bath, Monty pulls the plug chain and drains the bath, foiling the murder just as it seems about to succeed. The dog's loyalty to Kronin proves decisive.

Foreshadowing: Kronin's efforts to befriend Monty during the months of captivity, including protecting the dog from Riordan, plant the seeds for this survival.

  • poison
  • monty
  • survival
  • acid bath
  • dog loyalty
Q5

What clues make Superintendent Finsbury suspect Riordan?

Finsbury notices small details that don't add up. During his visits to Riordan's office, he picks up on Riordan using American-sounding phrases, which seems unusual for a British psychiatrist. He also observes how Riordan interacts with Americans in a way that suggests hidden knowledge. These subtle behavioral tells, combined with the missing American case, make Finsbury increasingly suspicious.

Foreshadowing: Finsbury's initial visit is ostensibly about Riordan's missing dog, but his perceptive questions reveal deeper investigation.

  • finsbury
  • police
  • suspicion
  • clues
  • investigation
  • scotland yard
Q6

Why does Riordan decide to poison Kronin when he overhears Storm and Finsbury talking?

Riordan overhears a conversation between his wife Storm and Superintendent Finsbury that confirms police are closing in on him. Realizing the investigation is intensifying and his carefully constructed plan is at risk of unraveling, Riordan panic-strikes and poisons Kronin in a desperate attempt to accelerate the murder before authorities can connect him to the crime.

Foreshadowing: The timing of Riordan's escalation directly follows Finsbury's investigation, showing how external pressure triggers his worst impulses.

  • poison
  • desperation
  • police
  • discovery
  • storm finsbury
Q7

Why does Storm leave after visiting Kronin in the hospital?

Storm visits Kronin as he recovers and tells him she plans to travel abroad for a while. Her departure suggests the affair has fundamentally damaged her marriage and life in London. Rather than staying to face the consequences or rebuild relationships, she chooses to leave both men behind, indicating the relational wreckage left in the wake of Riordan's crime.

Foreshadowing: The affair itself set all these events in motion, and Storm's position between both men has been impossible from the start.

  • storm
  • departure
  • hospital
  • affair
  • leave
  • travel
Q8

Why does Kronin protect Monty from Riordan?

During his months of captivity, Kronin develops a bond with Monty, the dog who visits the hidden room. When Riordan considers killing Monty, Kronin refuses to let that happen, he actively protects the dog from harm. This connection proves crucial, as Monty's resulting loyalty saves Kronin's life by foiling the acid bath murder.

Foreshadowing: The daily visits where Kronin observes and befriends Monty establish their relationship before it becomes plot-critical.

  • monty
  • kronin
  • loyalty
  • protection
  • dog
  • bond
Q9

What happens at the end of the film?

Riordan's plan completely unravels when police find his car in the garage and discover the hidden room with Kronin still alive. Finsbury reveals that Kronin survived, so Riordan escapes a murder charge for now, though he remains under scrutiny. The film ends with Storm leaving both men, Kronin in the hospital and Riordan facing uncertain consequences, while Monty, loyal to Kronin, jumps his lead to stay by the bedside, suggesting an unusual bond formed through captivity.

Foreshadowing: The dog's final leap to Kronin's side echoes their earlier connection, where Kronin's kindness to Monty was rewarded with survival.

  • ending
  • climax
  • police
  • arrest
  • kronin survives
  • storm leaves
  • monty
Q10

What drives Dr. Riordan to plot such an elaborate murder?

Riordan's motivation stems from discovering his wife Storm's affair with American Bill Kronin. As a psychiatrist accustomed to control, the betrayal sends him into a cold, calculated rage. Rather than confronting the situation directly or seeking divorce, he channels his jealousy and wounded pride into orchestrating the perfect murder, removing his rival while keeping his wife unaware of the danger.

Foreshadowing: The film opens with Riordan learning of the affair, immediately setting the revenge plot in motion.

  • motivation
  • jealousy
  • revenge
  • affair
  • betrayal
  • control
