I'm coming up toward the half-way mark or thereabouts in Our Mutual friend. Enjoying it very much. I have to keep checking the Dramatis Personae at the front to remind myself of the large cast, but that's fine. Its shaping up well anyway, and I like the use of dust as a symbol and feature of the books. Jenny Wren is terrific, and Sloppy reminds me of Toots from Dombey, in some ways. London is portrayed especially vividly in this book and it would be a good choice to read if you're a fan of Dickensian London; more so than some other novels perhaps.
