There are two possibilities here, neither of them good:
1) A woman with an unsavory past, who has done desperate things to get out of terrible economic conditions, was raped by a prominent figure, and he's going to get away with it because of her history.
2) A serial cad had consensual sex with a chambermaid, and she attempted to destroy him with a false rape allegation for personal gain. And because of the presumption that women don't lie about rape, she has succeeded in destroying him (and destabilizing the IMF at a very delicate moment), though not so much in the personal gain part. To quote Ray Donovan, "Where do I go to get my reputation back?"
Neither is very comforting. But that's all we have at this point. An official contacted by the Times sums it up perfectly: "It is a mess, a mess on both sides".
