I think I'd much prefer "Marta gets caught up in another mystery" to "Benoit Blanc solves another mystery"; I'd like to see more of her, and she's much more interesting when she's in over her head than Blanc is when he's swanning around being confident he's going to get to the bottom of everything.

Part of me is saying "Marta has a lot on her plate already, she deserves a break", but I can't decide whether that's an argument for or against the idea.
