The Isdal Woman

Her movements can be reconstructed for several weeks before her death from hotel forms and the decoded notebook: Stavanger on 29 October, Bergen from 30 October to 5 November, and other Norwegian cities under other names⁠[2]⁠[5]. Her last hotel was the Hordaheimen in Bergen, where she stayed mostly in her room. Staff described a good-looking woman of about 163 cm with dark brown hair who kept to herself and paid in cash. She checked out on 23 November, asked for a taxi, and was not seen alive again⁠[1].

At the scene the body lay on its back in a "fencer's position", arms raised, the front badly burned; the fire had been fed with petrol, traces of which were found on a fur hat beneath her⁠[5]. The autopsy at the Gade Institute concluded death from a combination of phenobarbital poisoning and carbon monoxide; the pills in her stomach and blood amounted to a large dose, and more lay beside the body⁠[1]. Her teeth carried extensive gold work of a kind not done in Scandinavia, and her jaw was kept for comparison⁠[8]⁠[2].

The witnesses are hotel staff, travellers and others who met her in Norway in 1970, interviewed by police at the time and some re-interviewed by NRK and the BBC in 2016-2018⁠[1]⁠[9]. They describe a reserved, well-dressed woman who wore wigs, changed rooms after checking in, said she was a travelling saleswoman or antiques dealer, spoke German, French, Flemish or broken English, and was once overheard talking in German with a man⁠[1]. A fisherman reported to the navy that he had seen a woman fitting her description near the Penguin missile test area at Tananger; the counter-intelligence police recorded the report in December 1970⁠[10]⁠[4]. A man who said he saw her walking with two men on a hillside days before her death came forward publicly only in 2005; his account was not recorded at the time⁠[9].

The police file includes the scene report and photographs, the autopsy, the handwritten hotel forms, the decoded notebook, the contents of the suitcases, the description sent to Interpol and the secret police file on the missile-test sighting⁠[5]⁠[8]⁠[4]. Parts of it have been released through NRK and the BBC, and the case material is in the Bergen State Archives⁠[2].

The 2016-2018 forensic work produced three results. A full DNA profile was obtained from preserved tissue by the Norwegian Institute of Public Health and circulated internationally⁠[1]⁠[6]. Strontium and oxygen isotopes in teeth formed at different ages, measured with the University of Bergen and interpreted against European isoscapes at the University of Canberra, point to a childhood around Nuremberg and a later move west, toward the French-German border⁠[6]⁠[7]. At the Karolinska Institutet, the absence of bomb-pulse carbon in her wisdom tooth showed birth before 1944, and aspartic acid racemisation in three teeth gave 1930 plus or minus four years, so she was between 36 and 44 at death, not about 30 as thought in 1970⁠[6]⁠[11]. Handwriting analysis had already suggested schooling in France or a neighbouring country⁠[1]. The DNA is police property and, as of 2019, had not been searched against commercial genealogy databases for legal and ethical reasons⁠[12].

Suicide. The police conclusion: she took a large dose of sleeping pills and set fire to herself⁠[5]. The pills and the soot are consistent with this⁠[1]. Against it, as several investigators noted at the time: the neck bruise, the effort taken to remove identity from her belongings and the difficulty of setting a petrol fire while heavily drugged⁠[1].

Killing, or a death arranged with another person present. Someone gave or forced the pills and set the fire, or was present when she did⁠[1]⁠[13]. It explains the bruise and the late report of companions, which was not tested in 1970⁠[9]. No suspect or physical trace of another person has been published.

Espionage. The false identities, the travel to Stavanger and Tananger during Penguin trials and the counter-intelligence interest suggest she was working for a foreign service⁠[4]⁠[10]. No intelligence service has confirmed it, and the sighting report is second-hand. Other readings, that she was a courier or a sex worker travelling under aliases, rest on her travel pattern and behaviour at hotels, not on documents⁠[13]. None of these readings explains her death by itself.

A name would change everything else. The DNA profile exists; a search of genealogical databases that permit police use, or of national DNA and missing-persons registers in Germany, France and Belgium, could find relatives, as it has in other unidentified cases⁠[12]. The isotope result narrows the search to regions where a girl born around 1930 could be traced through school, registration and emigration records. Release of the counter-intelligence and defence files from 1970 would show what the security services knew. A modern re-examination of the autopsy record and the preserved tissue would test the bruise and the pharmacology against the suicide finding.
