Rowling had the above twixter conversation with journalist and friend Janet Murray (no known relation to husband Neil Murray) about both women’s struggles to maintain iron levels in their blood. Rowling mentions as an aside her being “diagnosed with von Willebrand’s disease” (VWD) by a haemotologist. VWD is “the most common hereditary coagulopathy in humans, affecting 1% of the population” per Wikipedia.
This was not a revelation, though her discussion of her daily concern with absorbing iron certainly was (imagine writing the haemotologist Roy Phipps scenes in Troubled Blood while surviving on a diet of 90% kale…). She had tweeted about being “born with a bleeding disorder” in December 2025 and Nick Jeffery noted at the time that it was probably VWD because of its prevalence in the population and its appearance in Strike 5. Rowling’s 9/11 tweet confirmed Nick’s Best Guess.
Nick went on from his first post to catalogue in his ‘The Troubled Blood of J. K. Rowling‘ the Blood Golden Thread’s appearances and meaning throughout Rowling’s work. That brilliant exposition was followed up by a Rowling Studies conversation on the same subject, ‘Blood: The Crimson Thread.’ If you were unaware of that strand or commonplace in nearly everything Rowling has written, it’s a fascinating study in the intersection of Rowling’s biographical Lake inspiration and her Shed artistry by which she elevates blood to a social, psychological, and spiritual metaphor.
I confess, though, I’m most interested in Rowling’s ideas about blood because of a twitter header she posted when writing Troubled Blood: [Read more…]


Having just finished the month-long Lake and Shed celebration of J. K. Rowling’s opera omnia, my dominant feeling is one of pride. Recording somewhat over 31 hours of video, mastering (or at least becoming competent) in video editing for the intro and getting to grips with the technicalities of rendering and uploading the content to Substack and You Tube, all within a month, was a challenge that I wasn’t sure I could pull off. Twenty-five episodes were dedicated to individual works of Rowling, and in each episode only a single example of lake inspiration or shed artistry was explored. The mine is so rich that we could easily produce another hundred and twenty-five episodes and still not exhaust what J. K. Rowling has achieved.
