Unmasking the Killer in the Alberte Case

The unmasking of the killer in the Alberte case comes when Rose’s examination of Bjarke Habersaat’s old computer and a photograph in Christian Habersaat’s papers expose the clues that Department Q had pursued in the wrong direction. The evidence identifies Bjarke as Alberte Goldschmid’s killer and reveals the motive behind the collision: Bjarke was in love with Frank Brennan and resented Alberte for taking Frank’s attention. It also recasts Christian’s prolonged investigation. He had suspected his son, but could not bring himself to pursue him, and had followed the alternative possibility that Frank was responsible.

The clues inside the computer

Rose works through Bjarke’s old computer and reports that forty-five percent of its memory is occupied by games, some so old that she doubts Bjarke had played them for years. The computer runs Windows 95. Image files take up fifty-two percent of the memory, spam accounts for two percent, and the remaining find is a single text file: a poem titled To Frank. It was tucked among executable files in a 1995 Star Trek game, a location that made it easy to miss.

The poem’s meaning is not subtle. Rose reads it aloud, and its inept writing does not obscure its emotional force: rejected love and anger at Frank for bringing Bjarke’s world crashing down. The poem blames Frank for the ruin of Bjarke’s family and even expresses anger that Frank exists. Its title and contents turn a stray computer file into evidence of an attachment that Bjarke had not disclosed openly. At this point, the poem does not by itself explain the collision; its importance lies in giving the earlier clues a motive and a human connection.

The photograph and the false trail

The decisive visual clue is a photograph of Bjarke standing beside a four-wheel-drive vehicle fitted with a plow. He is grinning in his Boy Scout uniform, wearing his cap, shoulder cord, and a belt knife decorated with small shields. The plow bears the words BOY SCOUT GRAND CHRISTMAS TREE SALE—MERRY CHRISTMAS. The image presents the vehicle and its attachment not as an obscure object in a crime-scene theory, but as part of Bjarke’s own apparent Christmas-tree-selling enterprise.

For Carl Mørck, the photograph instantly overturns the accumulated casework. Department Q had pursued a wooden board because of a small splinter Christian had found, searched for the VW Kombi, and devoted days and resources to leads and interviews that had pointed suspicion toward Frank, also known as Atu. Now the investigators recognize that the central vehicle evidence has been misread: Bjarke had a plow of his own. The photograph makes plain how a seemingly minor detail could redirect a long investigation, and why Rose’s work matters. She has connected the killer to an object that the inquiry had treated as part of a different trail.

Rose presses the implication further by asking whether Christian could really have failed to know that his son owned the plow. Carl answers that Christian was a policeman who had sacrificed seventeen years to the case, and insists that he did not know. Rose proposes a more unsettling interpretation: Christian may have suspected Bjarke for years and pursued the case so persistently because he needed to settle that suspicion, while the possibility of his wife’s lover offered a more convenient target. Her theory captures the uncomfortable question raised by the photograph, but Christian’s own account gives a more divided explanation than deliberate misdirection.

Christian Habersaat’s account

In a written statement dated April 29, 2014, Christian explains that his suspicion of Bjarke had strengthened after Alberte’s death, when he found the object Bjarke had apparently used to sell Christmas trees. He remembered his son working on something of that sort and had found it while the island was searching for it. Yet Christian also knew of the relationship between his wife and her former lover. His island network supplied indications that the man with the VW Kombi was the same man who had met Alberte, and the splinter found at the crime scene, along with other evidence, gave him hope that his suspicion of Bjarke was mistaken.

Christian describes two impulses pulling against each other: the desire for revenge and the urge to protect. He could not find a motive for Bjarke to kill a girl who was, as far as Christian understood, a stranger. He also knew that Bjarke was not interested in women, a subject that had caused repeated arguments between Christian and June. Those details help explain why Christian’s suspicion did not immediately become a conclusion. He had grounds to suspect his son, but a motive remained opaque until he found the poem.

Christian says he found it about a month before writing, while using Bjarke’s old room for investigation materials. It was in a box with old PC games. The poem showed him that Bjarke was in love with the same man as Christian’s wife and had killed Alberte after being displaced by the younger girl. Christian concludes that Bjarke must have written it afterward, probably shortly before moving out. What had looked like an inexplicable attack on an unknown girl becomes, through the poem, an act rooted in rejected love and resentment.

Recognition and its cost

Christian’s letter is both an explanation and an admission of failure. He apologizes for insisting on pinning the crime on an innocent man when his son had committed it. He does not claim that every earlier suspicion of Frank was baseless: he had known about Frank’s connection to June and had received reports linking Frank and the VW Kombi to Alberte. Rather, the letter shows how those leads competed with a suspicion he could neither resolve nor act upon. He leaves Bjarke’s fate to the investigators because he cannot bring himself to go after his own son, and declares that the matter stops with him.

The discovery therefore solves the case while exposing the personal cost of its delay. The computer’s obsolete games, the poem hidden in one of them, and the photograph of a smiling Scout beside a Christmas-tree-sale plow converge to identify both a motive and a vehicle clue. For Carl and Assad, the revelation replaces the apparent pursuit of Frank with the truth about Bjarke. For Christian, it confirms the suspicion he had tried to balance against hope, loyalty, and the evidence pointing elsewhere. The investigators stand silent after reading his words; the solution brings certainty, but not relief from what the truth means for a father and his son.
