Policía Foral de Navarra

Policía Foral de Navarra is the police organization Amaia Salazar names when identifying herself to a resident and when displaying her badge during an inquiry. The novel depicts it not through a formal account of its structure, but through the practical work of its officers: responding to a death initially classified as sudden infant death, testing that explanation against physical evidence, and widening the investigation when records and patterns raise further questions. Its authority is visible at the door and in the field; its effectiveness depends on patient collaboration with specialists and on revising conclusions as new evidence arrives.

Identity and Presence

When a young social-services worker asks whether Amaia is a relative of the man inside a home, she answers that she is with Policía Foral de Navarra. The exchange establishes the institutional identity behind her visit, while the worker’s earlier explanation supplies the immediate context: social services bring the resident meals because he cannot leave and has no one to care for him. The exchange places police work alongside, but distinct from, social care; Amaia’s presence does not make her a family member or caregiver.

The organization’s local presence is also conveyed through Amaia’s identification at a private property. Fina Hidalgo challenges the visitors’ right to enter; Amaia shows her badge and explains that the gate was open and they had rung the bell. On another occasion, a woman remarks that Amaia seems young to be an inspector. These encounters make official identity concrete: officers must establish who they are and explain their presence, but a badge does not itself resolve the questions their investigations raise.

Investigation and Evidence

The inquiry into the death of Valentín Esparza’s four-month-old daughter shows the distance between an initial diagnosis and a criminal explanation. Iriarte recounts how the child died while sleeping at her grandmother Inés Ballarena’s home, where the death was certified as sudden infant death. The grandmother later recalled hearing a noise inside, then a vehicle on the gravel outside, and seeing a large gray car leave around four in the morning. The timing mattered because the estimated time of death was between four and five. Her account, her son-in-law’s nervous response, and the dogs’ failure to bark prompted suspicion, but none alone established how the child died.

The police then worked with Forensic Doctor San Martín, who reported a pressure mark across the bridge of the child’s nose, soft white fibers in the folds of her lips, and saliva traces that included a sample different from the child’s. Subsequent findings tied the pressure mark and fibers to the nose of a stuffed bear found with the child’s body. The child’s and Valentín Esparza’s saliva were identified, while a third, foul-smelling sample remained unexplained. The sequence illustrates the organization’s reliance on specialist examination: officers can identify a question and request tests, but the forensic results refine what can responsibly be claimed. The unexplained sample, in particular, remained an anomaly rather than proof of a particular source.

Coordination and Case Development

Policía Foral de Navarra’s investigative work extends beyond the immediate scene. Amaia directs Zabalza to see whether the images and audio can be enhanced, while asking Jonan Etxaide and others to accompany her. The recorded material appears to show someone handing something over, but the spoken name cannot be understood; enhancement is a possibility, not a guaranteed solution. This moment presents investigation as coordinated work in which a lead may be worth pursuing even when its value is uncertain.

The inquiry also depends on exchanges with medical professionals. A review of infant deaths in Navarra identified seventeen deaths attributed to sudden infant death over five years, four in the Baztán area. Two of those cases had prompted later inquiries by social services, though the available records showed no further developments before the cases were closed. A forensic doctor who had performed autopsies on two girls remembered normal findings and no evidence that their deaths were unnatural, but also recalled troubling parental behavior. Her recollections added context without overturning the autopsy conclusions. The novel thus distinguishes a reason to investigate from a finding that proves criminal conduct.

Records, Limits, and Institutional Role

The same distinction governs the search for Ainara Martínez Bayón’s history. A police colleague presents her birth certificate, which records a home birth at Argi Beltz and bears Doctor Hidalgo’s signature, but finds no death certificate to support the family’s account that she died in England. A contact’s checks uncovered no hospital record of her death, no autopsy record, and no evidence in the family record that her death had been entered. The colleague also explains that a Spanish citizen’s death abroad would ordinarily be communicated to the embassy, while noting that passport records from thirty years earlier could take time to verify. The missing documents are significant gaps, not by themselves a complete account of what happened.

Amaia’s later work with a map shows how separate case records can be reorganized into a testable pattern. Using a file of previously investigated infant deaths, Jonan’s added entry for Amaia’s sister, and locations marked on a map, she notices that the relevant places trace the course of the Baztán River. The pattern redirects her thinking, but it does not replace the need for corroboration. Elsewhere, Amaia plans to inspect birth and death records connected with Fina Hidalgo and seeks judicial authority to pursue that line of inquiry. The case therefore presents policing as a process constrained by evidence, records, and legal permission, not as a power to treat suspicion as verdict.

The organization’s narrative significance lies in this procedural tension. Its officers must act before every uncertainty is resolved, yet their conclusions remain provisional: a diagnosis can be questioned, a witness’s recollection can open a line of inquiry, and a striking pattern can suggest where to look next. Forensic analysis, digital review, document checks, and judicial authorization each contribute different kinds of knowledge. Policía Foral de Navarra emerges through that accumulation of work, and through the discipline of distinguishing what the investigation has established from what it has only begun to suspect.
