Really? I see all kinds of fascinating stuff about gender and identity in Bohemia - most foregrounded, that it's about Irene choosing to move between the class/gender roles of Bad Girl and Good Wife, and what she has to do, to manage that, and the way then men's preconceptions about those two categories keep them from seeing what she's actually doing. The identities she moves between are roles that are not nearly as distinct in the modern day as they were in the late 19th/early 20th century, but it's huge in the context of where the story was originally set.
