The Black Monday Murders would be an interesting TV series
Although thinking about it, the best candidate for a John Hickman TV series would probably be Pax Romana. It can be adapted to be a bit like Game of Thrones (including the politics, battles, sex, etc), but with a dash of sci-fi, historically recognizable settings, and a religious pseudo-philosophical background issue. Plus it *is* essentially a huge conspiracy theory, and would let you plug in pretty much any shadowy group as you might as the thing progresses.
