A Conversation about Cormoran Strike, Literary Alchemy, and Structural Models for the Ten Book Series

Nick Jeffery and John Granger sat down last weekend to discuss John’s post, The Literary Alchemy of Hallmarked Man: What Do the Structural Models Tell Us? (hogwartsprofessor.substack.com/p/the-literary-…) They’d talked about this subject briefly (hogwartsprofessor.substack.com/p/wet-squibs-is…) before John had written it up and he came to rather different conclusions in the process of writing and preparing slides for the post, all of which are rolled out in this inquisition.
The questions Nick asked are below after the links in the post in case you want to follow up on what is said above about literary alchemy, the sequence of colors and symbols, and about the structural models for understanding the Strike series, especially Extended Play and Tetractys Theory.
Enjoy!

The Ten Questions and John’s Answers (notes!)
1. So, John, you finally got the alchemy post you promised an age ago; what was the hold-up?
· Tried to put too much into the posts…
· Changed my mind several times as I was writing them!
· had to relearn Tetractys ideas!
2. You start off this Alchemy of Hallmarked Man discussion with a review of the literary alchemy of the first three Harry Potter novels; why did you have to reach that far back?
· Because of the Parallel Series Idea, not alchemy at all, oddly enough.
· Rowling seems to be writing Strike decalogy in parallel with Potter to include its alchemical sequences so I reviewed the ‘Reverse Alchemy’ theory, how that worked for Strikes 1-3 but broke down at 6 and 7
· To get Hallmarked Man‘s alchemical stage right, I wanted to figure out why Ink Black Heart and Running Grave weren’t the alchemical stages we’d expect
3. Some of our listeners may not have the literary alchemy three stages firmly in mind; can you go over what they are and why they’re important in Rowling Studies?
· Black, White, Red stages: what each represents in metallurgical and literary alchemy;
· Rowling’s one interview comment about alchemy, her PotterMore notes about colors;
· Rowling’s use in Harry Potter‘s last three books, fourth book, and first three books;
· Galbraith’s use in Strike series’ first three books, fifth book, and six and seven;
· Ward on astrology in CSL’s Narniad (’Donegality (archive.nytimes.com/schott.blogs.nytimes.com/2…)’); similar use of alchemy in Rowling-Galbraith
4. So the alchemical parallelism seemed to stop at Ink Black Heart but the other correspondences continued?
· That’s right, the first seven books paralleled their Harry Potter apposite numbers in structure, plot points, and some symbolism but the last two broke from the alchemical pattern;
· I decided that the best place to look for a way that the new pattern could be explained would be looking at the seven theories about the Strike-Ellacott series structure;
· If a specific structure had a very clear idea about the alchemical stage sequencing in the books, then I’d have a real head-start in what to look for in Hallmarked Man.
5. The Seven theories -- last time we talked it was six! Remind me what they are and what each says about the alchemy...
· No structure, Big Ring/Double Wedding Band, Septology and trilogy combo, Extended Play, Corona Sonnet, Tetractys, and Celtic Cross (see links above!);
· Only Extended Play and Tetractys theories had clear theories about the alchemy; and
· …
