Niamh O’Connor, The Black Widow: The Catherine Nevin Story (Dublin: The O’Brien Press, 2006)

‘Black Widow’ is popular vernacular for a female who kills, or solicits the killing of, a domestic partner, usually for financial gain. The term has travelled widely around different national settings and been stretched in many interesting ways. For example, in Russia since Vladimir Putin's ill-conceived invasion of Ukraine, the label has been applied to women who marry soldiers solely for ‘coffin money’. They are Black Widows of a kind, but the label has, historically in the true crime literature, been applied to a female who marries a male to grab his money, not through his death on the battlefield, but by being murdered directly at the Black Widow's hands in peacetime. Both types of Black Widow are money-oriented, but they commit qualitatively different types of offence using very different means.   

Niamh O'Connor's valuable book shows that Catherine Nevin’s self-aggrandising financial plot relied on the constant and prolonged manipulation of relatives, friends, work colleagues and those in her local community. Information was her main currency. She creatively mixed partial truths about her marital relationship to her husband Tom Nevin, with a series of lies and evasions. Catherine Nevin spun dense narrative webs (or life stories that were only partially grounded in reality) that helped her evade suspicion by deflecting attention from her actions and, when the crime was discovered, eliciting public sympathy for her plight. As O’Connor points out, “All her life, Catherine manipulated other people by wielding information over them – like a weapon… As a seasoned liar, she could take a grain of truth and spin whatever version of events she desired” (p32). Black Widows are patient, calculating and will happily play the long game, at least until they have their administrative ducks in a row. This can take many years of planning.

Nevin, like many Black Widows, including Jean Daddow in my book, never showed remorse for her atrocity, maintaining her innocence until her death from cancer in 2018. Like Daddow, she exhibited clear narcissistic tendencies; equated money with power and social capital; showed no empathy or emotion when faced with the reality of her actions; and was fuelled by an unwavering conviction that she was fully entitled to ostentatious material wealth, however she got her hands on it. Black Widows live by the motto ‘damn everyone else’ – other people are treated as pawns in the game of furnishing the Black Widow with as much wealth as possible. To maintain a veneer of respectability  to divert attention while they concoct and execute their schemes, Black Widows have to spend a great deal more time than most offenders cultivating a certain self-image. Peel back the ‘grieving widow’ veil of victimhood, though, and the average Black Widow’s personality ‘back-stage’ is rather more prosaic, grubby, potentially violent and, ultimately, deadly.

Tom Nevin was shot through the chest at point blank range in the early hours of 19 March 1996, as he sat alone, counting the day’s takings from Jack White’s, the pub he owned with his wife Catherine near Brittas Bay in County Wicklow, Ireland. Tom was taken by surprise – there was no sign of a struggle. Catherine Nevin was first arrested and questioned for 48 hours on 28 July 1996 (p177). In the course of the investigation Nevin pointed the finger at some ten other suspects (pp182-90). She was, however, charged with Tom’s murder on 14 April 1997 (p181). On 11 April 2000 Catherine Nevin was found guilty by unanimous verdict on all four charges against her: one of murder, three of soliciting to murder. Judge Mella Carroll handed her a mandatory life sentence (p236), following – at 42 days – what was, then, the longest trial in Irish legal history (p218). 

The jury heard that Nevin married her husband with the intent all along of building up a successful pub and property rental business, making him disappear, then hoarding the proceeds for herself. Their relationship was alcohol-fuelled, difficult and chaotic, with provocateur-in-chief Catherine engaging in a string of extra-marital affairs, often with members of the Dublin police and judicial world, which publicly shamed Tom, degraded his self esteem and damaged him emotionally. The affairs were also part of her scheme (see below). Pub cleaners and bar staff all knew the couple had taken to sleeping in separate bedrooms. Catherine’s lovers came and went more or less as they pleased because she gave them the keys to the pub. While the glamorous publican waited for the most opportune moment to strike at her husband, she rinsed the pub for financial gain in a series of smaller ways: “While the Nevins were in Jack White’s, Catherine made fourteen insurance claims”. Six were for damage apparently caused by storms, flooding and a fire; the rest were for theft, including of a wedding ring, which mysteriously reappeared soon after the payout. In total, she collected not insignificant sums from twelve of the claims (p85).

To help her cause, after the Nevins took over at Jack White’s, Catherine went on a one-woman mission to implicate those local police officers with whom she was not already having an affair, in various fabricated crimes, nearly ruining several of their careers in the process. Her thinking was that, if her murderous machinations were exposed, she could claim it was police retribution for her truth-telling. “Many gardai believe that Catherine deliberately cast herself in the role of champion against corruption in the force so that should she ever be charged with the murder she was planning, she could claim she had been set up” (p73). By 1993, Catherine had made seven statements alleging corruption against two local garda officers, as well as a false claim of sexual assault against one of the men (p80). She also insinuated that Tom – or herself, or both, depending on audience – had connections with the Irish Republican Army (IRA), which was still very active north and south of the Irish border, in the mid-1990s. Catherine enjoyed the status these alleged connections gave her. More importantly, she used them when questioned by police as a potential explanation for Tom’s murder – he had got in over his head with the wrong people, who happened to have ready access to guns. The lies Catherine Nevin told were nothing if not creative.

In the years before Tom was shot, Catherine solicited three men to kill her husband. Like Jean Daddow who arranged my father's murder, Catherine saw herself as the General in the war, others could be the cannon-fodder, taking the hit (literally) for her. Her first solicitation was to Willie McClean, who was offered £20,000 to dispose of Tom in 1990 (p126). The second solicitation was to John Jones, over the course of 1989-90, where she leveraged the nationalist narrative: “I want you to get the IRA to shoot my husband…in what would look like a robbery” (over £20,000). Catherine revisited that proposition with Jones six or seven times over the next year and a half, all to no avail (pp131-2). The closest she got to a successful solicitation was via Gerry Heapes. He was offered £35,000: £10,000 up front and £25,000 in the takings they would make off with during the supposed ‘robbery’ (p145). Heapes – a confessed IRA man and convicted armed robber – put out some feelers to ‘the right people’, but was, bluntly, told the IRA did not get involved in domestic disputes. 

Frustrated that she kept getting knoocked back by the designated cannon-fodder, Catherine decided to act, it seems, on the belief that she had exhausted all credible options to make Tom disappear: “She was at her most dangerous when she was losing. And nobody knew where the next strike would come from” (p69). But why did the pair not simply divorce? Even though they were living in a toxic relationship that made them both incredibly unhappy, Catherine did not want to separate from Tom “because she wouldn’t settle for half the pub and property. She believed she was entitled to all of it” (p252). Tom was equally steadfast in his belief that he would not give up what he had worked hard for, and was desperate to avoid disappointing his mother with the failure of a second marriage (Catholic ‘shame’ surely played a role in Tom's thinking).

Tom’s principles would be the death of him because, “One single theme continuously recurs throughout Catherine Nevin’s life. When she could not control something, she destroyed it” (p36). Significantly, Tom died without a valid will, meaning Catherine stood to inherit everything. He also had a life assurance policy worth over £70,000 (p181). In a brazen move that shocked Tom’s family, the first thing Catherine did after his murder, in fact, was to fill out the paperwork to take sole proprietorship of Jack White’s, channelling her request via a judge with whom she had had a long-standing affair. The conflict of interest, or the idea of corruption, clearly did not matter to the judge, who signed the pub over to Catherine despite her having been charged with murder. Within three months Nevin had sold the pub at a huge profit, although the money was frozen after the guilty verdict (p114). Later, the State undertook a full-scale inquiry into the judge’s actions in relation to Catherin Nevin’s post-murder licensing request (p115).

There was rumour of a possible accomplice or assassin who might have fired the shot on Catherine Nevin’s behalf (p240ff), but the jury agreed with the prosecution barrister that Tom’s own wife had pulled the trigger herself. Under cross-examination, her stories about her life with Tom, and the night of the murder, were proven to have more holes in them than the average colander. Her stint on the witness stand shows, firstly, that “a good liar needs a good memory” (p219), and secondly, that the Black Widow’s greed usually outweighs their intelligence. Catherine Nevin was convicted on all four charges laid at her door (one of murder, three of soliciting to murder) and was handed a mandatory life sentence.

The judge saw through Catherine's attempts to smear her husband's name to justify the murder, telling her: “You had your husband assassinated and you tried to assassinate his character as well” (p251). For, as with Jean Daddow, O’Connor reports that Catherine went on a one-woman campaign to make Tom look like the 'bad guy' in the relationship. For example, she falsely claimed Tom was homosexual, a severe negative in a strongly Catholic country. She would get an eyelift and then show the post-surgery black eyes to people, pretending Tom had hit her. She also insisted Tom get treatment for his alcoholism, which he undertook at the St John of God’s Hospital in March 1993. Together with the black eye claims, “After his death, his admission to hospital backed up her claim that she was the downtrodden wife of an abusive drunk” (p47). However, a patient who met Tom during his treatment said in court that Tom did not believe he had a drink problem. He may only have agreed to undertake it “to get Catherine off his back”. If anything, of the pair of them, Catherine was the alcoholic. Tom’s 'addiction' treatment, along with the rest of her domestic abuse stories, was all part of the lies wh wove to tarnish the character a defenceless victim (p199). 

As the close of the book vividly illustrates, even in death there is little respite from a Black Widow for a victim or their family. After Tom’s funeral, at which the 'grieving widow' was naturally front and centre, Catherine installed four elaborate, verbose, headstones over his grave. They combined highly insensitive wording (“murdered”) and a highfalutin religiosity that rubbed salt into the bloody wounds the Black Widow herself had caused. True to type, Catherine also “made discreet enquiries as to whether should could claim VAT back for the headstones” (p170). Her lack of remorse was further demonstrated when Catherine – unsuccessfully – appealed her conviction in 2003, putting the family through more needless suffering. What we learn from O’Connor’s fine book is that greed and a high sense of self-entitlement can make for a dangerous cocktail. In the hands of a narcissist with delusions of grandeur, the cocktail can be deadly. Ultimately, though, many Black Widows end up caught in webs of lies and deceit they themselves have spun, as hard as they try to mask their plotting behind lies and sob stories.
