Fiber Sample from Jonan’s Apartment

The Fiber Sample from Jonan’s Apartment is a tiny, bright fragment of cloth that Amaia Salazar discovers at the scene of Jonan Etxaide’s murder. Its significance lies less in any confirmed identification than in the chain of choices and dangers it sets in motion: Amaia notices what might otherwise be overlooked, preserves it outside the formal forensic process, and gives a sample to Doctor Takchenko, whose subsequent roadside attack suggests that someone may be trying to recover it. The fiber remains materially slight and evidentially unresolved, but it changes the investigation by making a nearly invisible trace seem capable of pointing toward the killer.

Discovery at the Apartment

Amaia finds the fragment while alone in Jonan’s apartment, after the forensic examination and as the trauma-cleaning crew is about to begin its work. The apartment’s familiar objects intensify her sense of Jonan’s absence: she sees the things he used and touched, but can find no remaining trace of his presence. His blood, once intimately his, has become something repellent and exposed to flies. In that atmosphere of grief and forensic scrutiny, she re-examines the room rather than simply leaving it to be cleaned.

The sofa gives her a reason to revisit the forensic doctor’s theory that the shot came from below, from the position of someone sitting down. Amaia sits, raises a hand as if holding a gun, checks whether the sofa has been moved, and looks beneath it for signs of dragging. Finding the dust undisturbed, she turns toward the window to air the room. Opening it brings in a cold draft that stirs the curtains. A few millimeters of gray, shiny fiber detach from one curtain and travel across the bloodstained floor. The fragment is close enough in color to the curtain to seem part of it, yet Amaia can see that its weave is different. She looks through the rooms for a matching fabric and finds none.

Preservation and Initial Assessment

Amaia photographs the fragment from several angles with her phone. When Markina calls, she answers but says she cannot continue talking; her attention remains on the trace. After hanging up, she searches a sideboard for an advertising envelope, empties it, and carefully places the cloth inside. She notices a repeated design that almost looks like a letter and judges the material to be rich and delicate, although she is not a textile specialist. A more extensive inspection of the curtains and other surfaces reveals nothing else beyond the fingerprint powder.

The find is uncertain from the outset. Amaia recognizes that the fragment could have been caught on the curtain for a long time and hidden by its similar color. The scientific team has already done careful work, and she considers the possibility that the fiber may prove irrelevant. But uncertainty is not the same as permission to discard it. Because the cleaners are about to work in the apartment, she keeps the fragment rather than risk having it swept away with the material being removed.

At the Beloso police station, Amaia tells Clemos that she found the fiber just before the trauma cleaners started and offers it to him. He objects that she should have called the forensic team. Amaia replies that, without her presence, the cleaners might have destroyed something that could be evidence. Before handing the material over, she goes to a second-floor bathroom, puts on gloves, cuts a thin filament from the fragment, returns that filament to the envelope, and wraps the rest carefully in a sheet of paper. The careful division preserves material for analysis while making the act itself an unofficial intervention in the evidence chain.

Analysis and Expanding Danger

The fragment is passed to Doctor Takchenko, the Russian doctor who performs parallel analyses for Amaia’s team. After Takchenko is struck in a road incident, her husband tells Amaia that she is alive but badly injured and in intensive care. Witnesses reported that another vehicle had been involved; two men climbed the hillside, got into their car, and drove away. The car was searched thoroughly, with the contents of Takchenko’s bag and luggage scattered and the spaces beneath the seats and inside the glove compartment checked. Her husband suspects that the men were looking for the envelope containing the sample.

The envelope had arrived by courier from Pamplona, and Takchenko herself had drawn attention to the connection by reminding her husband that Amaia had given her something to analyze. Amaia identifies it as a fabric sample. The doctor proposes Andreas Santos, a specialist in forensic textiles whom he has known for years. Santos has examined fabrics recovered from a stork’s nest in Alfaro, including material dated to the medieval period, and has assembled an extensive record of European textiles and weaves from the past ten centuries. His expertise offers a way to ask more of the fragment than a basic compositional analysis might reveal. The available account does not give Santos’s findings, so the sample’s precise origin and evidentiary value remain undetermined.

Amaia later explains to Fermín Montes that she gave the fiber sample to Takchenko for parallel testing, and that someone subsequently forced Takchenko’s car off the road and searched it. Amaia also reports that an intruder entered her own home and took an empty pen drive; she had asked Montes to keep watch at her aunt’s house in case the intruder went there next. These events do not establish who targeted the sample or what the intruders knew, but they place the fragment within a pattern of attempts to reach investigative material. Takchenko’s decision to send it by courier, which Amaia initially had not fully understood, now appears to have reflected an awareness of its possible importance and of the danger attached to it.

Evidentiary and Narrative Significance

The fiber’s force comes from the tension between its minute physical presence and the disproportionate risk surrounding it. It is not a dramatic object recovered through a planned search: a gust of air dislodges it while Amaia opens a window for an ordinary practical reason. Its movement across the floor makes a hidden difference visible, and Amaia’s attention turns that accident into a preserved trace. The fragment participates in the investigation through its material properties—its shine, unusual weave, and absence of an obvious match in the apartment—before anyone can say what it is or whom it implicates.

The sample also exposes the vulnerability of evidence once it leaves a controlled forensic setting. Amaia handles it herself, divides it by hand, and entrusts part of it to a specialist working outside the usual local analysis. Those choices produce a possible lead, but they also complicate custody and place Takchenko at risk. No confirmed match or final identification is supplied. The fiber therefore remains a clue defined by both promise and incompletion: a few millimeters of unfamiliar cloth, noticed amid grief, preserved against routine destruction, and pursued as though its smallness concealed a larger secret.
