A Night of Provocation

The Scene Is Prepared
Jacqueline performs rage
Jacqueline drinks heavily in the saloon, sings about a betrayed lover and demands another drink. Simon remains nearby while Cornelia listens and Fanthorp watches.
Witnesses gathered
The apparent quarrel draws attention and establishes Jacqueline as emotionally volatile. The witnesses and the growing commotion will later make the shooting seem like a spontaneous outburst.
The Gunshot

A Wound Before Witnesses
The apparent attack
Jacqueline fires her pearl-handled pistol, and Simon falls with a wound in his leg. She appears horrified by what she has done and drops the weapon beneath a settee.
A carefully useful injury
The shooting appears to make Jacqueline dangerous and Simon helpless. In fact, it creates the first half of an alibi that keeps each conspirator away from Linnet’s cabin in the public account.
The Confusion Afterward

Control of the Scene
Witnesses disperse
Fanthorp and Cornelia remove Jacqueline to her cabin, where Miss Bowers stays with her. Simon urges them to keep Linnet uninformed and asks that the doctor be summoned.
An unattended weapon
The pistol remains hidden under the settee only briefly. Someone who knows where it fell can take it before Fanthorp returns, making the aftermath the crucial opening for the murder plan.
A Convenient Alibi

The Shot That Excludes Them
Jacqueline under supervision
Miss Bowers confirms that Jacqueline stayed in her cabin after the shooting. Witnesses also establish that she could not have left the saloon before the gun went off.
Simon apparently disabled
Dr. Bessner confirms Simon’s fracture and treats him in his cabin. The injury seems to exclude him too, hiding the brief interval in which he could have acted.
The Performance Exposed

The Two Halves Join
Poirot reconstructs the timing
Poirot shows that Simon used the confusion to shoot Linnet, then wounded his own leg and discarded the pistol. Jacqueline’s staged rage supplied the witnesses and the supervised alibi.
A false separation
What looked like a violent breakup was the conspirators’ most important collaboration. The apparent conflict between them was a performance designed to make suspicion land elsewhere.
