A Nervous Witness

A Nervous Witness
An eager offer
Slimane Bahtoum volunteers for tests and insists he did not touch the dead man. His anxiety looks like possible guilt to Darac, who notices how quickly the young man tries to establish his innocence.
A discrepancy in dress
Darac questions why Slimane wore tight cargo trousers for repeated prostrations. The detail is not proof, but it opens a practical line of inquiry into whether the person identified as Slimane was actually present.
The Swap Exposed

The Swap Exposed
Pressure breaks the story
Darac takes Slimane outside and suggests that witnesses and cameras will disprove his account. Slimane begins to cry and admits that someone else had been beside Florian.
A cousin arrives
Mansoor Narooq appears and identifies himself as Slimane’s cousin. The physical resemblance explains why the substitution worked and shifts the investigation from a simple murder suspect to a deliberate cover story.
An Illegal Immigrant’s Fear

An Illegal Immigrant’s Fear
A motive for concealment
Mansoor admits that he asked Slimane to replace him because he feared that police questioning would reveal his immigration status. The fear is not imaginary: he could be transferred to authorities who might deport him.
A civic complication
Darac recognizes the humanity of Mansoor’s situation while continuing to investigate a murder. The case brings law enforcement into tension with the quotas that reduce individual lives to administrative totals.
A Window Escape

A Window Escape
An unexpected leap
When Esquebel’s phone is activated, Mansoor hears it and jumps from an office window in an attempt to flee. He is badly hurt but survives, forcing the police to turn their attention from interrogation to emergency care.
A clue becomes a misreading
The escape seems to confirm suspicion, but Mansoor’s reason is fear of detection rather than guilt in Florian’s murder. The leap adds urgency and confusion to an already unstable investigation.
The Undercover Reveal

The Undercover Reveal
A second identity
Efe Santoor explains that Mansoor is his cousin and that the identity switch was part of an undercover operation targeting Hamid Toulé. The DCRI had encouraged the deception after deciding that Florian’s death might provide an opening.
Trust damaged
The revelation shows that Darac’s team was used without its knowledge and that a staged escape was designed to expose its methods. The cousins’ lie now sits within a wider institutional deception.
