I can't remember who said it first, but I 100% agree that Marian Halcombe should have been the main character of The Woman in White (@animate-mush you quoted someone else saying this? I think?). I get that a female character couldn't dart around the country investigating like Walter can, but she could, for instance, have been the one to collate all the documents and draw the conclusions. That didn't all have to be Walter.
What I find fascinating is... I think Bram Stoker came to the same conclusion? His capable, efficient female character with initials MH is at the centre of the narrative: she collates the documents, and she at least co-directs the energies of the men. Marian almost vanishes from the story in Epoch 3; Mina is there from start to finish. I genuinely wonder if the boys learn to regret excluding Mina because Walter never learned to regret excluding Marian.
If so, good work, Bram. You did do it better.
