A true crime book is supposed to arrive after the verdict. The trial is over, the files are closed, and the author reconstructs what happened for readers who want the story. Sometimes the order runs the other way. A reporter spends years in the paperwork of a case the courts consider finished, and the book that results forces the courts to look again, or tells a country what it chose not to notice, or sets two competing versions of a dead man’s confessions against each other.
Seven cases belong here, and none is here for literary merit. In each a book, or the reporting behind one, altered what was known or done. Sometimes the alteration was legal: convictions quashed, compensation paid. Sometimes it was a shift in attention or a correction of a legend. In one case it was nothing of the kind, and the book matters for what it shows about the limits of the form.
Between 1994 and 2001, six Swedish district courts convicted a psychiatric patient named Sture Bergwall of eight murders. He was held at the Säter hospital in Dalarna and had taken the name Thomas Quick. In therapy and then in police interviews he had claimed responsibility for dozens of deaths in Sweden, Norway and Finland; counts of the claims run from more than 20 to 39, depending on the source. A police compilation presented at one trial listed 29. Much of the evidence in the cases that reached court was his own account.
In 2008 he withdrew every confession. Retrials followed between 2009 and 2013. In the case of Yenon Levi, an Israeli visitor to Sweden, a prosecutor dropped the charge in May 2010 and Falu District Court entered an acquittal that September. In the case of Therese Johannessen, a nine-year-old from Drammen, Norway, the Svea Court of Appeal ordered a retrial in September 2010 after concluding that supporting evidence, whether from witnesses or technical analysis, was entirely missing. By then a Swedish forensic laboratory had examined the fragments that two professors had once judged probably human and concluded that they came from neither a human nor an animal. The prosecutor dropped the case in March 2011. The last acquittal, in the case of Charles Zelmanovits, became final on November 26, 2013. The chief prosecutor who dropped that charge said the conviction had rested mainly on the confession and on Bergwall’s own wish to be convicted, and that no one knew whether the boy had been killed at all.
The books enter this story in two places. The journalist Dan Josefsson, in Mannen som slutade ljuga, argued that a theory of repressed memory sat at the center of the trials, that the psychologist Sven Christianson helped persuade police, prosecutors and courts to accept it, and that a senior psychotherapist exercised great influence over the case. Christianson has said he never testified about repressed memories and that the convictions did not rest on psychological explanations. The dispute ran in the Swedish press for years, and Josefsson answered his critics publicly in March 2014.
The second book was by Hannes Råstam, an investigative reporter. As the London Review of Books blog summarized his work in 2013, he traced Bergwall’s information to newspapers, to hints dropped during police contact and to cues given while he was driven to sites, and showed that many of his statements were simply wrong. Bergwall had read press coverage in public libraries while on leave from the hospital.
What the court record shows is that the system the books criticized did reverse itself. A government commission reporting in June 2015 concluded that investigators had accepted the explanation that he struggled to recall events whenever he gave a wrong or incomplete answer, that the interview method used did not keep investigative findings from Bergwall, and that the risk of false memories was not taken seriously enough. It noted too that he had been treated for years with benzodiazepines and developed a severe dependence. A Norwegian review reached similar conclusions about the part played by police and prosecutors there. Moved to open care on March 19, 2014, Bergwall ended forensic psychiatric care in April 2015 and was living freely in Jämtland as of September 2016.
Which of these accounts moved the courts cannot be read from the court record alone. The prosecutors who dropped the charges cited the thinness of the evidence, not any book. But the books supplied the public with an explanation of how eight convictions had been built, and the prosecutor Christer van der Kwast later published a book of his own, announced in November 2014. In 2018 Swedish public television reported that the affair would be made into a film.
In March 1983 a jury in Trondheim convicted Arnfinn Nesset, the manager of a care institution for elderly people in Orkdal, of 22 murders and one attempted murder. He was acquitted on two further murder counts. He received 21 years, then the heaviest sentence Norwegian law allowed, with 10 years of preventive detention. United Press International called it Scandinavia’s biggest peacetime mass murder case. The substance used, according to the verdict, was Curacit, a muscle relaxant used in surgery that he had ordered in large quantities.
There was no technical evidence. NRK reported that the prosecution rested on what witnesses had seen and experienced and on the record of the police interrogations. Those interrogations were enormous. NRK put the total at nearly 1,000 hours, often 10 to 12 hours at a stretch; the news agency NTB gave 967. During them he confessed to killing more patients than he was convicted of killing: 27 by NRK’s count, 30 by UPI’s and NTB’s. Shortly before the trial he withdrew all of it, and he pleaded not guilty on every count.
His defense lawyer, Morten Gunnes, said in 2024 that police never called him in and that he never attended an interrogation. He told the lawyers' magazine Advokatbladet that he held letters in which Nesset repeatedly asked police to contact him. Nesset, Gunnes said, never told him in their prison meetings that he had confessed to killing anyone.
For four decades the case stood without a serious challenge. Then, in 2024, at 87, Nesset gave his first press interview and said he wanted the case examined again. In autumn 2025 the journalist Simen Sætre published a book whose title, as NTB and the trade press reported, refers to 31 confessions. His argument was that several of them were probably false. Sætre said in an interview with Journalisten that the book had not turned out the way he planned it.
Nesset died in a nursing facility in December 2025, aged 89. His lawyer confirmed the death on December 3. No court had reopened the case. In August 2026 the news site Altinget and the legal outlet Rett24 reported that a journalist had been awarded a Norwegian prize for rule-of-law work for digging into the Nesset case. Nesset’s own conviction stands. What the book changed was the question being asked about it: not whether he had said the words, but what 967 hours of questioning, conducted without his lawyer in the room, had produced.
John Martin Crawford was convicted of manslaughter in the death of Mary Jane Serloin, 35, in Lethbridge, Alberta, in 1981. He was sentenced on June 16, 1982, to 10 years and was released in 1989; accounts differ on whether he served five years or seven. Three First Nations women then died near Saskatoon, Saskatchewan, in 1992: Eva Taysup, Shelley Napope, 16, and Calinda Waterhen, 22. Crawford was arrested in Saskatoon on January 19, 1995, and in 1996 was convicted of one count of first-degree murder and two of second-degree murder. He received three concurrent life sentences and died in the Regional Psychiatric Centre in Saskatoon on December 16, 2020, aged 58. The cause was not released.
The case drew little notice beyond Saskatchewan. The journalist Warren Goulding asked why, and the book he published in 2001, Just Another Indian: A Serial Killer and Canada’s Indifference, offered an answer built from several causes: race, geography, incompetence and economics. A reviewer in the Canadian Book Review Annual wrote that limited coverage had left Crawford a virtually anonymous figure. The book followed the case from the RCMP investigation through the appeals, and as Windspeaker’s reviewer summarized it, set out the record of an unusually long period in which police had contact with him. In May 1992 a woman reported an assault to police. He was out on bail by June. In October 1992 he was charged with attempted murder in the beating of a Saskatoon man; the outcome of that charge has not been reported. He spent most of 1993 in the Saskatoon Correctional Centre for another assault.
The family history in the book is as telling as the police history. Waterhen’s father went to the RCMP about her absence in May 1993 and again in October 1994. He was told, the review recounts, that she was somewhere in Saskatchewan and that her health card was still in use. Napope’s aunts said years later that it took three years before their niece’s death came to light, that police gave the family false statements and false hope, and that in all that time no reporter asked about her. The RCMP, Goulding reported, had kept Crawford under surveillance for four months in 1994 and had held back a public warning to build their case. A woman who said she was assaulted in that period filed a claim against the RCMP nearly six years later alleging negligence.
The prosecutor, Terry Hinz, told Goulding he saw no reason the Paul Bernardo case should have received more publicity than this one. Windspeaker’s reviewer compared the book to Conspiracy of Silence, the account of the 1971 death of Helen Betty Osborne in The Pas, Manitoba.
The book did not alter any verdict; Crawford was already in prison. Its effect was on attention. In 2003 the Institute for the Advancement of Aboriginal Women gave Goulding a social justice award for it, at a ceremony in Edmonton attended by relatives of Taysup and Napope. Napope’s aunt said Goulding had been respectful to the family. The institute’s founder said real awareness would begin when the killing of Aboriginal women stopped. Goulding told the paper that he had meant the book as a tribute to the women and not a true crime story in the usual sense.
When Crawford died, Goulding told 650 CKOM that his thoughts were with the victims' families and that the media had been quick to lump the women into a category, grouping them by assumptions about their lives. Of the man himself he said he did not know whether there was a good side to him at all.
Kieran Patrick Kelly was an Irish laborer born in Rathdowney, County Laois, in 1929 who spent his last free years in the parks of south London. In 1984 he was convicted at the Old Bailey of the murder of Hector Fisher and the manslaughter of William Boyd, two men who lived as he did. Boyd died in 1983 in a police cell at Clapham that he shared with Kelly, after Kelly was arrested in the area. Kelly received a life sentence and died at Frankland prison in Durham in 2001.
What kept his name alive was what he said afterward. Questioned by detectives, he described killing men over about 30 years, beginning in 1953. The reported counts range widely. The Irish Post said in 2019 that he confessed to upwards of 10 more murders; its 2015 coverage said 16; Scripps News said 18. Robert Mulhern, the Irish journalist who spent years on the case, noted in 2016 that the numbers attached to Kelly had run from 12 to 14 to 18 and up to 31. None of these killings beyond the two in 1984 was proved in court.
The books were responsible for the larger figures. In the summer of 2015 Geoff Platt, a retired police officer who had received a commendation for work on the original investigation, published The London Underground Serial Killer. It claimed Kelly may have been responsible for as many as 31 deaths in London between 1953 and 1983, many of them on the Underground, and that the Home Office had suppressed the Underground deaths to prevent panic. Platt quoted the Home Office as having said it received a police report but deemed it not of public interest. The British Transport Police told Scripps News they were aware of the claims but that these would be hard to verify after so long. The Irish Post reported that the claims prompted the Metropolitan Police Commissioner of the time, Sir Bernard Hogan-Howe, to commit to revisiting the investigation. No outcome was reported.
Mulhern’s work took the opposite course. His radio documentary for RTÉ, reported in 2016, and his book The Secret Serial Killer concluded that the higher figures do not stand up but that Kelly was nonetheless dangerous. He said his research showed that Kelly had been acquitted of another London murder in 1977 and that two attempted murder charges were dropped in 1982. A detective on the 1980s investigation put the likely total at five or six. In 2020 and again in 2023 an RTÉ podcast and television series, The Nobody Zone, returned to the recordings; the production team had 120 minutes of the 1983 police audio. Ian Brown, a retired Metropolitan Police detective superintendent who worked the case, said in the series that Kelly showed animal cunning and at times seemed to be playing the police. Mulhern, for his part, asked whether Kelly was telling a story, manipulating the detectives, mad, or confessing to crimes he had not committed to make the whole account unreliable.
The two books do not even agree on the man’s biography. The 2015 summaries of Platt’s account have Kelly arriving in London in 1953, around the coronation, after service in the Irish Army; reports on the RTÉ productions say he joined the British Army at 18 and was dismissed in 1951, and the Leinster Leader’s extract from Mulhern’s book says he emigrated to England in the 1960s. The record settles none of this. The case is useful here for a plain reason: a single set of recorded interviews and a single short list of verdicts produced a 31-victim legend in one book and a five-or-six estimate in another, and nobody was ever in a position to test either.
Eric Edgar Cooke was hanged at Fremantle Prison on October 26, 1964. He was 33, a married father of seven from Perth, and the last person executed in Western Australia. A jury had convicted him of a single wilful murder, that of John Sturkey, an 18-year-old student, at Nedlands in January 1963. By the time he died Cooke had told police he had killed eight people and tried to kill 14 others between 1959 and 1963, and that he had committed more than 250 break-ins, ABC News reported in 2017. The Australian Dictionary of Biography records that the state acknowledged him responsible for two other murders. The rest were never tested in a court.
Two of his confessions concerned deaths for which other men were already in prison. J.B., then 19, had been convicted of the manslaughter of his girlfriend, Rosemary Anderson. D.B., a deaf young man who could not speak, had been sentenced to death for the murder of Jillian Brewer, and the sentence was commuted. J.B. confessed in police interviews without his parents or a lawyer present, according to the reporter Estelle Blackburn; decades later he told the Central Western Daily that detectives had beaten him until he did so. A jury returned a verdict of manslaughter in May 1963. D.B. was convicted in 1961. Cooke’s confessions to both deaths went before the courts in 1964 as evidence in the other men’s cases, and the court gave them little weight; the dictionary records Chief Justice Sir Albert Wolff calling him a villainous unscrupulous liar. J.B.'s appeals in 1964 failed. D.B.'s failed through the Privy Council in 1965.
About 15 minutes before he was hanged, Cooke reportedly swore on a Bible that he had killed both women. The Law Society of Western Australia’s exhibition on wrongful convictions says a clergyman recorded the statement and that a copy is held in D.B.'s court file. It changed nothing. Blackburn wrote that when the hanging went ahead, both men understood there would be no reprieve for them, and the Central Western Daily reported that police opened no inquiry.
The cases were reopened because of one journalist. In 1991 Blackburn, a Perth newspaper, radio and television reporter, met J.B.'s brother at a social occasion, and the conversation led her to look into Anderson’s death. She went through police and prison files, trial records and press reports, and located witnesses who had never been interviewed. She spent six years tracing the families of Cooke’s victims through electoral rolls, phone books and door-knocking; she told Canberra CityNews in 2020 that, with one exception, she gathered the story of every murder victim’s family. Her book, Broken Lives, appeared in 1998, and a later version, The End of Innocence, was published by Hardie Grant in 2007. It also sets out 12 assaults and attempted murders by Cooke that police had concealed.
On February 25, 2002, the Western Australian Court of Criminal Appeal quashed J.B.'s conviction, and the Attorney General welcomed the vindication that day. In June 2002 the Attorney General announced that D.B.'s conviction would go to appeal. The court quashed it on April 1, 2005, after about 40 years. The state awarded J.B. $460,000 in April 2003. An ex gratia payment was made to D.B. in June 2011, and a radio report put it at more than $400,000. Fremantle Prison’s records note that 44 people were hanged at its gallows between 1888 and 1984; Cooke was the last.
No other case among these seven produced a clearer chain from the book to the verdict. It also shows what the chain cost: the reporter’s years, the men’s decades, and a confession that sat in a court file for 38 years before anyone treated it as evidence.
Władysław Mazurkiewicz was a currency dealer, driving instructor and gambler in postwar Kraków, born in the city in 1911. In August 1956 the Voivodeship Court in Kraków tried him for six murders, committed between 1943 and 1955, and two attempted murders. He was convicted, sentenced to death on August 30, 1956, and hanged at Montelupich prison on January 29, 1957; the magazine Focus gives the date as January 27. The press called him the elegant murderer. In the city he was Piękny Władzio, handsome Władzio.
For six decades the case was told largely through rumor. Two stories hardened into received wisdom: that Mazurkiewicz had been a Gestapo informant during the German occupation, and that he had later worked for the communist security service, which protected him. The writer Marek Hłasko, who reported on the trial for the weekly Po prostu, wrote years later that he thought it likely the man had collaborated with the security police. Histmag quotes his line that everyone in Kraków knew Mr. Władzio was a murderer but assumed he was carrying out the sentences of his masters.
Cezary Łazarewicz’s book Elegancki morderca, published by W.A.B. in 2015 and built on the case files, tested the stories. Łazarewicz told Radio Kraków that he checked the files of the Institute of National Remembrance and located no trace of work for the security service. The Polish Press Agency and Magazyn TVN24 reported the same. Histmag has suggested that Mazurkiewicz may have started the rumor himself, which TVN24 supports, adding that fear kept people from questioning it. Przemysław Słowiński’s 2017 book on unsolved killings in communist Poland took the opposite view, describing ties to the security service in the early 1950s that helped shield him. A negative result in an archive does not close the question, and Łazarewicz did not claim that it did. The episode most often cited by believers in protection is the 1945 inquiry into the death of the currency dealer Józef Tomaszewski. Villagers had written down the registration number of a car, it was Mazurkiewicz’s, and he was nonetheless cleared; a prosecutor friendly with him, TVN24 reports, took statements from witnesses in a village pub.
The book also corrected the record in a different way. Investigators had first drawn up just over 30 charges, according to Histmag, most dropped for lack of evidence; the indictment that reached court held eight. The figure of about 30 victims, repeated in the press, was never proved. Most of the confessed crimes had no supporting evidence beyond his own statements, RMF FM reports, and the confession, obtained in March and April 1956 after his wife and half-sister were arrested and threatened with charges, became the backbone of the indictment. He withdrew it on the twelfth day of the trial, August 27.
Łazarewicz drew his own conclusions with restraint. He described killings that were planned, without emotion, and for money, by a man who remembered which victim carried which watch or ring but not their names, and he told Radio Kraków that he did not classify Mazurkiewicz as a serial killer. He also said no psychologist had ever examined the man, so any theory of his childhood, which included his mother leaving the family, could only be a guess. The book reached the Kraków International Book Fair in 2015. A feature film, Śpij kochanie, directed by Krzysztof Lang, went into postproduction in 2017.
The last case is the exception. Donald Henry Gaskins, known as Pee Wee, was a small, wiry roofer from Florence County, South Carolina, born in 1933 according to the South Carolina Encyclopedia (a public radio history gives 1931). Between 1976 and 1978 he was convicted of murder by two juries and pleaded guilty to eight further counts of murder. In its 1985 opinion the South Carolina Supreme Court listed the seven earlier killings covered by a long confession he gave in 1978. A federal appeals court noted in 1990 that before the case that finished him he was already serving ten life sentences.
That case was a murder committed inside the Central Correctional Institution in Columbia in September 1982. Rudolph Tyner, a death-row prisoner convicted of the 1978 murders of a store-owning couple, was killed in a plot organized by the couple’s son through intermediaries. Gaskins recorded several of the telephone calls that arranged it, and the State used the tapes. A jury convicted him of capital murder in March 1983, the sentence was affirmed on January 22, 1985, and he was electrocuted in Columbia on September 6, 1991, aged 58.
Dick Harpootlian, the prosecutor in that last trial, wrote a book about the case with the journalist Shaun Assael, published in 2025. It changed no verdict, because no verdict was in question; Gaskins had been dead for 34 years. What the book supplied was a view from inside the courtroom and the prosecutor’s office. Harpootlian has said he personally opposed the death penalty but felt bound by his oath, and that he concluded a death sentence was justified as a kind of self-defense because prison walls had not stopped Gaskins from killing. "If not Pee Wee, who?" he said at his book launch in 2025. He told South Carolina Public Radio that Gaskins presented himself as pleasant company, a man people around him liked.
A book written by the prosecutor decades after the execution is a different instrument from the rest. It cannot exonerate and does not pretend to. It fixes a version of the record, in the voice of the person who stood in court, at a moment when most of the other participants are gone. That is its worth and its risk, and the reader of any such book is entitled to remember that the author had a side.
Set side by side, the seven books performed four different jobs. Blackburn’s reporting produced legal consequences: two convictions quashed and compensation paid. Råstam and Josefsson laid out how eight convictions had been assembled. Sætre, Goulding and Łazarewicz altered the terms on which a case was discussed, whether the question was the reliability of a confession, a country’s indifference or a city’s legend about its own protected killer. Platt and Mulhern produced numbers that no court will ever test, and the public has been left to choose between them. Harpootlian’s work records a case that was already finished.
The pattern across all seven is that a book mattered most where the official file had a gap that an ordinary reporter could fill with patience: a witness never interviewed, a file never checked, a thousand hours of interrogation never questioned. It mattered least where the record was complete and the author’s authority rested on having been there.
