Recently I read The Seven Deaths of Evelyn Hardcastle by Stuart Turton which combines murder mystery and time loop. Was totally not trying to take my mind off The Running Grave's impending release >.> It's a bit confusing at first, since you know only as much as the main character does. It ended up being quite interesting, though some plot twists at the end felt a bit over the top.
One thing that stuck out to me was that, like in the Cormoran Strike series, there's a character named Madeline.
The Seven Deaths of Evelyn Hardcastle came out in 2018, while The Ink Black Heart was released in 2022.
Since Galbraith/Rowling loves her literary allusions, I took another look at Chapter 3 (same chapter where she name-drops Tannhäuser) and noticed two things that seem to point at a deliberate reference on her part:
Strike and Madeline meet at a club called Annabel's
Madeline is part of a "party of eight"
(This probably won't make any sense if you haven't read The Seven Deaths of Evelyn Hardcastle, or The 7 1/2 Deaths of Evelyn Hardcastle as it's called in the US).
On purpose or not, I find the reference somewhat fitting, considering what we later learn about Madeline. I'm not going to say more because I don't want to spoil anybody.
