Is Rowling's Incest 'Golden Thread' the Key to Her Cormoran Strike Finale?

Golden ThreadsLast July, Nick Jeffery and I put together a month long review of Rowling’s work in celebration of her 60th birthday, a Kanreki party. Every day we posted conversations about each of Rowling’s works with Nick discussing a ‘Lake’ point, something biographical or bibliographical, and me talking about a ‘Shed’ quality of the work, the author’s traditional tools, artistry, and meaning.That worked great for about twenty days. Then we ran out of books. What to do for the remaining days of the month?We decided to talk about Golden Threads, the plot points, themes, and twists that run through everything Rowling has written. We started out with a survey of the fifteen-plus already identified by Rowling Re-readers and Fourth Generation types (see here and here) and then with more in depth looks at the ones that were controversial or more difficult to see. We closed off the month with the ‘Lost Child’ Golden Thread and the possibility that Rowling’s inspiration for the Harry Potter series was the trauma of pre-natal infanticide (‘abortion’).As disturbing as that Golden Thread was to many Rowling fans and Feminist Gate Keepers, there was another third-rail string we didn’t discuss, namely, the plot point of incest that readers encounter again and again in the Potter and Strike series as well as the stand-alone stories.Incest as Golden ThreadNick and I discuss the Incest Golden Thread on the fly in the conversation above about Strike-Ellacott fandom theories about Sleep Tight, Evangeline and the series finale. Here are some written references if you want to review them by looking at the books in question on your shelf.* Harry PotterThe foundation crime of the Hogwarts Saga is the abuse of Merope Gaunt by her father Marvolo and her brother Morfin. The abuse in question in this children’s book series is not explicitly sexual. As with the abuse of Ariana Dumbledore by the Muggle boys, however, that Merope’s father and brother violated her is there between the lines; her trauma is so great that she loses her capacity for magic (as she does after her Riddle lover leaves her) and the family does not send her to Hogwarts lest their shameful secret be revealed. No broken Merope, no Lord Voldemort, no Potter family murder and orphan Harry — no series. Though the Saga’s foundation crime, the Gaunt family’s abuse of its only young woman, is not revealed until Order of the Phoenix, it is the tragedy on which all the core conflicts of the septology are built.* Casual VacancyStuart ‘Fats’ Wall is the adopted son of Tessa and Colin Wall. A teenager in Vacancy, he and Krystall Wheedon are the star-crossed lovers around whose choices and behaviors the ensemble drama largely turn. Fats at the end of the book claims responsibility for all the Ghost of Barry Fairbrother posts by means of which the secrets of Padford citizens are spilled.In the climax of the Wall family drama after Robbie’s drowning and Krystall’s suicide, Tessa reveals to Fats his personal history. His biological mother was only fourteen when he was born, an age that sadly means it is possible-to-likely that he is the fruit of incest. Tessa, a diabetic woman unlikely to carry a baby to term successfully, compelled her unwilling husband to agree to the adoption despite his mental fragility. Again, the foundation crime of this very involved story is incest, the abuse of a young woman by her family. * Lethal WhiteIn the first of only two Rowling books in which every epigraph was taken from a single work, the fourth Strike novel takes all of its headings from Henrik Ibsen’s Rosmersholm, a play in which suicide and incest go hand in hand, especially in the White Horse finale. The novel parallels its epigraph source in astonishing ways.The Chiswell family has its secrets. The Minister of Culture hires Strike’s agency to find ‘dirt’ on Jimmy Knight and Geraint Winn that can used as counter “bargaining chips” to end their capacity to blackmail him. He shares neither what information they have that they are holding over his head to extort money and revenge nor what Billy Knight witnessed years ago. If Jasper or Izzy Chiswell had told Strike this information in the beginning, it is likely the pater familias would not have been murdered. The biggest secrets, of course, are about the sexual relationship between Raphael and his step-mother and the step-son’s plans to murder father and eventually Kinvarra in order to be free to spend the millions he’ll make from sale of the Stubbs. Not quite incest, a step-mother in bed with her step-son, but something like it.Rosmersholm‘s family secrets are if anything more disturbing. Kroll reveals to Rebecca that Dr. West, her adoptive father, was very likely her biological father as well. It is implied heavily that after her mother’s death Rebecca’s relationship with Dr. West changed from filial to sexual; Kroll’s revelation about this is something of an Oedipus Rex moment. Rebecca realizes that she had been sleeping with her father and the incest taboo crushes her ability to accept Rosmer’s overdue marriage proposal, a proposal for which she had convinced the ailing Mrs Rosmer to commit suicide.* Troubled BloodThe psychopathic murderer and torturer of children that the police and public believe killed Margot Bamborough is Dennis Creed. We learn in chapter 8 of Strike 5 via the Peg-Legged PI reading The Demon of Paradise Park that Creed was the incestuous rape off-spring of Agnes Waite and her step-father Awdry, a man who wanted to kill the child at birth but which the mother prevented (to her eventual regret). Awdry abused the boy all through his childhood, especially after Agnes’ escape as a young woman (reminiscent of Peggy Nancarrow’s flight from St Mawes). Troubled Blood is haunted by the victims of Creed’s madness, all of whose deaths can be traced back to Awdry’s violent sexual violation of his step-daughter.* Hallmarked ManThe mystery Cormoran Strike agrees with no little hesitation to try to solve is ‘What happened to Rupert Fleetwood?’ Decima Longcaster Mullins, mother of Fleetwood’s son Lion, believes her baby-daddy was the unidentifiable murdered man in the Ramsey Silver Vault. We learn before that victim’s identity is revealed that Fleetwood fled the UK after he learned that the woman he loved was his half-sister and his son the product of unwitting incest. Rowling-Galbraith reveals only in the epilogue that Ian Griffiths murdered Tyler Powell because the young man was determined to rescue the young woman living with Griffith as his daughter who was pregnant with his child. Once again, the foundation crimes of a Rowling work turn on the intentional sexual abuse of a girl by a father-figure, here compounded by an Oedipus Rex like incest-in-ignorance episode. Incest Notes* Fantastic BeastsAs in the Harry Potter novels, there are no explicitly incestuous relationships in the Fantastic Beasts screenplays. The conception of Leta Lestrange, however, checks the ‘rape,’ ‘power abuse,’ and ‘inter-family’ boxes of father-daughter incest nightmare. Her mother, Laurena Kama, was desired by Corvus Lestrange III even though she was married to Mustafa and the mother of Yusof. Corvus compelled her by the Imperius Curse to join him and, while she was under his control, which is to say ‘unable to consent or resist his will,’ conceived Leta, who took his name as if her mother had been his wife. Leta unknowingly avenges the Kama family by her switching her younger half-brother Corvus IV with the Dumbledore baby that results in his death by drowning.* IckabogNick Jeffery points out in our conversation that there can be no more incestuous means of conceiving a child than the Ickabog species’ parthenogenic reproduction. If one accepts that as incest, the Ickabog’s death after delivery and the imprinted character of the Ickaboggle by its first contact post partum have to be read allegorically.* Cuckoo’s CallingThere is no mention made in the first Strike novel of John Bristow’s having sexually abused his younger also-adopted sibling-sister, Lula Landry. I’m going to include it in these ‘Incest Notes’ because I think it possible that the man who killed his brother Charlie and envied his sister Lula ‘played’ with her cruelly, which fostered her mental instability. I think this is more than imaginative free association head-canon because of Lula’s successful search for and planned meeting her real sibling brother Jonah Agyeman the night of her death. Bristow-Agyeman, the false and true brothers, are figures of erotic and anterotic love in her life, so much that I don’t think incest is a stretch for John Bristow, the unloved chick in the nest.Hogwarts Professor is a reader-supported publication.

The reason I’ve written up these thumbnail etchings of incest occurrences through Rowling’s work is because several of the theories Nick and I are seeing in the comment boxes here and on the YouTube HogwartsProfessor channel are incest driven.To get that, a Serious Striker, beyond grasping that incest is a ‘thing’ to expect in a Rowling piece like Bad Dad, Divine Mother, Violence Against Women, and at least one Lost Child, has to have in sight at all times three ideas that act as premises:* Closing Trilogy Theory: Hallmarked Man the first of a three book finale which introduces the main characters;There’s a real split in Strike fandom about what to think of Hallmarked Man. The great mass of readers on Reddit I’m told and at least one Substack Sage believe it is “the worst book of the series,” a real stinker. Nick and I — and most of the Hogwarts Professor readers who comment on our posts and conversations — in contrast think it is a brilliant book, one that may eventually be considered one of the best in the Strellacott decalogy.The difference is that the one group reads Strike 8 as if it were just like the first seven books in the series, i.e., a stand alone mystery whose cast of characters will in large part disappear from the stage before the next book begins. That working assumption makes the extraordinarily large cast of players in Hallmarked Man and the five different story-lines just with respect to whom the silver vault corpse might be, not to mention the Strike-Ellacott romance and over arching mysteries clues seem a confusing pile-up of plot points and people, few of which made this book fun-to-read. The author seems like she just lost control of the story and threw everything that occurred to her into the story and cut none of it out.Our working theory disagrees with that Just-Like-All-the-Others assumption and finds the possibility that Rowling has just lost her way very unlikely. Having just finished charting each of Strike 8’s chapter sets or ‘Parts’ and found that each is an intricate ring, as well as those Parts working as a ring, too, believing that the author is asleep at the wheel seems borderline preposterous.We think that the first seven books, each written playfully on the model of its Harry Potter numeric counterpart, are a closed set — and that the last three books in the ten book series are being written as a trilogy in which the Great Mysteries introduced in the first seven will be resolved.Hallmarked Man, as the first book in this three part series, is burdened with introducing all the principal players of this extended finale inside a book whose mystery allows their appearance and character reveal without pointing too obviously to their part in the upcoming drama. Hence Tara, Dino, Valentine, Ralph Lawrence, Sacha, and at long last Rokeby playing the roles they do in this book.* Trilogy will resolve at last the Leda Margaret, Charlotte, and Strike/Ellacott story line mysteries; The end of Strike 10 seems to be a hard stop according to Rowling. She is obliged, consequently, in the next two books to give her readers satisfaction on the many hanging threads in the series, most notably:* The story of Strike’s conception, the IED explosion, and his SIB medal;* Peggy Nancarrow, a.k.a., Leda Strike, why she left St Mawes as she did, why she raised her children as she did, and all the circumstances of her seeming suicide (Where’s Switch?); and* Charlotte Campbell-Ross, sometimes referred to as the Honorable Milady Bezerko, and the baby she claims to have conceived with Strike, her backstage efforts to upend Strike’s relationship with Robin, her break-up with the hotelier billionaire, her suicide note, and, echoing Leda, the circumstances of her seeming suicide.That’s the shortest of lists obviously with nothing about Murphy or Robin or the host of other key players in the series. Given the ending of Hallmarked Man, I’m very much inclined to think that Sleep Tight, Evangeline’s mystery will turn on where Robin went after Strike’s proposal on the stairs which will necessarily involve Murphy, and, forgive me, many of the players from Strike 8 as Rowling-Galbraith begins rolling out the stunning twists hidden beneath the surface of Strike 8. All those fun confrontations with Charlotte’s bizarro family, from Emilia at the end of Grave to Tara, Dino, Valentine, and Sacha? My bet is we’ll learn in the next books how much Strike and Ellacott missed in their meetings with each.* Serious Strikers think incest is at the heart of the Strike, Nancarrow, and Campbell mysteries.Leda’s Conception* Ted’s Daughter with an Unknown WomenA real stretch, I know, but Ted, per the invaluable Cormoran Strike Timeline, was fourteen years older than his younger sister Peggy. If you think it inconceivable that Ted was Leda’s father, you either imagine that just-barely-teenage boys cannot sire children (see George Hamilton’s life for his sexcapades at age twelve with his stepmother) or you make nothing of the fact that Trevik gave up his daughter for his mother’s upbringing when his wife died. Perhaps the cause of the Nancarrow house nightmare and Ted’s departure for the Army “lest murder be done” was because, a la Hamilton, Leda’s mother was not a young lass with whom Ted met outside The Victory but Trevik’s abused wife, Ted’s own mother. Which is to say he was both Leda’s brother and biological father. Hence the otherwise almost inexplicable relationship of Ted, his barren wife, and Peggy-Leda. Just sayin’!Strike’s conception:* Son of Leda and Ted;Leda is 23, give or take a year, at Strike’s conception early in 1974 and her older brother is 37 and married to Joan who cannot have children. It’s possible that Ted is Cormoran’s dad, just as Joan is delighted to hear Strike say he is in Troubled Blood, the only barrier being our being told repeatedly that Ted was a “proper man.” Perhaps that repeated telling is a marker that he wasn’t always that proper but did his best to set his sister (daughter?) up well with the Rokeby paternity evidence. See ‘Uncle Ted It’ for more speculation along these lines.* Son of Leda and Trevik Nancarrow;I’m thinking that if Rowling is pointing to an incest relationship in the Nancarrow family it isn’t with “proper man” Ted, the long-suffering and ever vigilant older brother but to the “pure terror” and “hard-drinking” man despised by sister and brother. You’ll forgive for thinking that anything to which Rowling-Galbraith is clearly hopeful her readers will believe is not the surprise ending of her ten book series.* Rokeby deception If Strike’s or Leda’s conception was incestuous, especially if Ted was the father of either, then Rokeby was deceived about his parentage, I presume with Ted’s SIB-driven assistance. The best motivation I have read about why Leda was murdered and her death staged as a seeming suicide, beyond even the Mad Guillespie theories, is that she tired of this deception, hence her refusal to accept Rokeby’s child support, and intended to tell Cormoran who his father really was. So Ted killed her. Charlotte Conception and Abuse by Father, Relations with Half-Brother:* Tara and Dino’s DaughterFiona wrote to me privately to share her theory that Dino is not only the father of Valentine, Cosima, Decima, and Rupert, but also of Charlotte:In response to a post by Cheryl Rose Orrocks on 17 Feb 2026, my current theory is that Dino Longcaster is Charlotte’s father and that his son, Valentine Longcaster, will be revealed as her abuser and the possible biological father of Charlotte’s children. Hence the 2nd incest storyline will also involve the Longcaster family. This could be why Charlotte’s mother, Tara, despised Charlotte so much.If Jago Ross is somehow linked to the matter of the DNA test involving Bijou and Strike, it may be because he had Charlotte’s birth children DNA tested to confirm parentage. Maybe Jago discovers he is not the biological father and assumes Strike is, hence the reason he wants to obtain Strike’s DNA results.This would need a whole longish post to unfurl but the high points of Fiona’s idea is that, just as with the Fleetwoods, Dino impregnated Campbell’s wife Tara unknown to the father. When the Campbells divorced (he doesn’t seem to have found out?), Dino then became Charlotte’s stepfather in addition to being her biological father.And maybe even the father of her children that she claimed were Cormoran’s and Jago’s? Whew.* Dino’s Sexual AbuseRubes posted her theory on a thread here on 3 March that Dino Longcaster abused Charlotte his step-daughter after his marriage to her then mother, Tara Campbell Longcaster:I think Charlotte got involved with Dino as a teenager (whether willingly or not). That is why she ran away and attempted to kill herself. She told her mother who disbelieved her or knew and it is the source of their conflict. Dino was also maybe the stepfather that tried to have her committed.Dino and his daughter [Cosima] gave me Ivanka and Donald Trump vibes. Maybe he sublimated that incestuous desire with young Charlotte. He is also obsessed with looks and perfection and we know Charlotte as Venus is the epitome of beautyI think Charlotte either extorted him all these years or else continued the on-and-off affair so he would help support her lifestyle.He might even be the father of the twins. It would support both the false paternity and incest themes in THM. We also have multiple examples of (step)fathers grooming/abusing their stepdaughters throughout the series.* Valentine or Sacha relations; Strike child, Ross twinsBoth the ‘Dino Did Her’ theories suggest in turn that, a la the Brockbank twins Noel and Holly, the Longcaster and Legard half-siblings Valentine and Sacha had sexual relationships with their beloved swinging sis Charlotte. Either man could be the father of the mystery baby she told Strike was theirs and either one could also be the baby daddy of Jago Ross’ supposed twins.As Fiona suggests, if the results of Bijou’s DNA testing of Strike winds up in Ross’ hands — perhaps Rowling makes the whole effort Ross-inspired after he discovers the twins are not his? — he is the one who reveals to Strike that neither of them was the father of Charlotte’s only children. If so, I look forward to reading how Rowling has Strike or Robin connect the dots with the incestuous Campbell-Legard-Longcaster family love-pit.ConclusionsDoes incest tie up all the loose threads in this series? No way. I suppose incest or at least cousin-marriage is a way of life in Afghanistan but I don’t see how incest explains for us all the questions surrounding the IED blast.But with respect to the several conception questions we’ve been straddled with, incest definitely throws up some fascinating possibilities (and ‘throws up’ reflects the nausea inducing aspects of this viscerally felt taboo). If you accept the Finishing Trilogy Idea and its corollary that all the mysteries will be resolved in the last three books and that Hallmarked Man has given us our cast of characters, then the possibility that the soft-incest of Decima and Rupert with its sort of happy ending in Strike 8 was an introit to an inbreeding heavy finish in the last two books.Please share your thoughts in the comment boxes below about these theories and about my conversation with Nick in the video above!Hogwarts Professor is a reader-supported publication.
