I must say I found JuliaMcKenzie one off putting. I do not watch much television and it was the first time I had come across the dramatisation of a book, where the script-writer had actually changed the plot, changing the killer and introducing a lesbian storyline, presumably to make it more 'woke'?
Plot changes are necessary when transferring from printed media to broadcast, and that is acceptable, but intrducing major changes in plot or characters just because you can, shows a sad lack of enterprise and originality.
